suppose your original tea happened to be a 10% solution of sucrose, and your pot contained 500 ml of tea. you diluted it with 200 ml of water. you now have 700 ml of tea. but what is the new concentration?

Answers

Answer 1

The new concentration of sucrose in the tea is 7.14%.

When a solution is diluted, the number of moles of solute (in this case, sucrose) remains constant, while the number of liters of solvent (in this case, water) increases. Therefore, the concentration of the solute decreases.

To calculate the new concentration, you would divide the number of moles of sucrose by the number of liters of the final solution (700 ml). In this case, the original solution was a 10% solution of sucrose, so it contained:

10/100 × 500 = 50 grams of sucrose.

After dilution with 200 ml of water, the new solution contains:

50/700 × 100% = 7.14%.

Therefore the new concentration is 7.14%

a fictitious element z has an average atomic mass of 223.13 u. element z has two naturally occuring isotopes. the more abundant isotope has an exact mass of 224.75 u and a relative abundance of 62.94%. calculate the exact mass of the second isotope.

Answers

The exact mass of the second isotope is  224.15 u

The following equation can be used to get the average atomic mass:

average atomic mass = (% of the first isotope/100) x mass of the first isotope+  (% of the second  isotope/100) x mass of the second isotope)

Due to this:

Initially isotope:

% = 62.94 %

Mass = 224.75 u

The second isotope is:

Since there are only two isotopes of the element, the second percentage is equal to 100 minus the first percentage.

% = 100 % - 62.94 % = 37.06 %

Assume Mass = x u.

Average Mass = 223.13 u, as stated

Thus,

average atomic mass = (% of the first isotope/100) x mass of the first isotope+  (% of the second  isotope/100) x mass of the second isotope)

223.13 = (62.94 % x 224.75) +( 37.06 % x 223.13 )

                   100                         100

When we solve for x, we obtain:

a certain hydrocarbon (a compound consisting of carbon and hydrogen) is carbon by mass and has a molar mass of . determine its molecular formula.

Answers

The molecular formula of the hydrocarbon having 82.76 % carbon and hydrogen is [tex]C_{4} H_{10}[/tex].

Hydrocarbon are defined as an organic compound consisting of hydrogen and carbon. These are the examples of group 14 hydrides. Hydrocarbons are colorless compounds and these are hydrophobic. The  odors of hydrocarbons are weak.

Suppose we have 100 g of the given compound. if there are 82.76 g of carbon then it should have 17.24 g of hydrogen in it.

The molar mass of carbon is 12.01 g/mol.

The molar mass of hydrogen is 1.01 g/mol.

We have to calculate the number of moles.

Number of moles of carbon = 82.76 g / 12.01g/ mole

                                                = 6.89 mole

Number of moles of Hydrogen = 17.24 g / 1.01g/ mole

                                                      = 17.07 mole

Now we have to divide the moles of carbon and hydrogen by the smallest value.

For carbon, 6.89 mole / 6.89 mole = 1

For Hydrogen, 17.07 mole / 6.89 mole = 2.5

Then the ratio becomes 2: 5. so the empirical formula is [tex]C_{2}H_{5}[/tex] having the weight of 29.07 g / mole.

n = molecular mass / weight of empirical

  = 58.1 g/ mole / 29.07 g / mole

  = 2

so the molecular formula becomes 2 * [tex]C_{2} H_{5}[/tex] = [tex]C_{4} H_{10}[/tex] .

What is the molecular formula for a compound that composed of 82.76% carbon having a molecular mass of 58.1 g/mole and is composed solely of carbon and hydrogen?

molecular formula is [tex]C{4H{10} }[/tex] for the hydrocarbon compound consisting of carbon and hydrogen.

An organic substance made up of hydrogen and carbon is referred to as a hydrocarbon. These group 14 hydride examples are shown. Hydrocarbons are invisible molecules that repel water. Hydrocarbons have hardly detectable smells. Consider that we have 100 g of the specified chemical. 17.24 g of hydrogen should be present if there are 82.76 g of carbon.

Carbon has a molar mass of 12.01 g/mol.

Hydrogen has a molar mass of 1.01 g/mol.

We must determine the amount of moles.

Number of moles of carbon = 82.76 g / 12.01g/ mol = 6.89 mole

Number of moles of Hydrogen = 17.24 g / 1.01g/ mol = 17.07 mole

The next step is to divide the moles of hydrogen and carbon by the least number. 6.89 mole / 6.89 mole equals one for carbon.

17.07 moles / 6.89 moles of hydrogen equal 2.5

Then, the ratio changes to 2 to 5. Therefore, the empirical formula weighs 29.07 g per mole.

n = empirical weight / molecular mass

29.07 g/mole / 58.1 g/mole = 2

Answers

According to law of definite proportion, the ratio of elements in calcium carbonate is always fixed. Thus on mole of calcium carbonate is 100 g which contains one Ca atom weighs 40 g. Thus,200 g of CaCO₃ contains 80 g of Ca.

What is law of definite proportion ?

Law of definite proportion states that, every compound will maintain a definite proportion of its constituent elements always irrespective of the source and method of preparation.

Therefore, all the elements in a compound will be in a fixed ratio with total mass of the compound. There is only one Ca in one formula unit of CaCO₃.

atomic mass of Ca = 40 g/mol

molar mass of CaCO₃ = 100 g/mol/

Answers

the specific heat capacity of the metal is  0.3427 J/g°C.

Water mass is 140.0 g.

Water started out at a temperature of 20.0 °C.

100 g is the mass of a specific metal.

Metal's initial temperature is 95.0°C.

Water and metal's combined final temperature is 24.6°C.

The water will gain heat because its initial temperature is lower than that of the metal, which will lose heat because it is at a greater initial temperature. Therefore, heat obtained by water equals heat lost by metal.

formula: (mass water)(finalT- initalT) = (mass metal)(initialT- finalT)(Cp metal) ( Cp water)

after entering the provided info we obtain,

(100g )(95°C -24.6°C)

(140.0g)(24.6°C–20.0°C) = (Cp metal) (4.184 J/g°C)

The formula is (100g)(70.4°C)(Cp metal)=(140.0g)(4.6°C)(4.184 J/g°C)

7863.7 g°C = 2694.5 J (Cp metal)

what volume of 6 m acetic acid is required to fully react with 0.5 g of sodium bicarbonate (nahco3)?

Answers

The volume of 6 M acetic acid required to fully react with 0.5 g of sodium bicarbonate is 0.099167 mL.

To determine the volume of 6 M acetic acid required to fully react with 0.5 g of sodium bicarbonate (NaHCO3), we need to use the balanced equation for the reaction between acetic acid and sodium bicarbonate.

The balanced equation is:

CH3COOH(aq) + NaHCO3(aq) → CH3COONa(aq) + H2O(l) + CO2(g)

From the balanced equation, we know that one mole of acetic acid reacts with one mole of sodium bicarbonate.

we know that the molarity is moles of solute per liters of solvent, so the number of moles in 0.5 g of sodium bicarbonate is 0.5/84 = 0.00595 mol

And since one mole of acetic acid reacts with one mole of sodium bicarbonate, we know that we need 0.00595 mole of acetic acid to fully react with 0.5 g of sodium bicarbonate.

If we know the molarity of acetic acid, we can calculate the volume of acetic acid required to react with 0.5 g of sodium bicarbonate. we have

K+ and NO3- spectators 2NO3- for each K+

Pb and K+ are equal but some Pb precipitate

Hence, giving the concentration order as,

[ NO3-] > [K+] > [Pb2+] and the concentration of the chloride ion becomes very small and hence it is negligible.

Basalt is an ingenious salt which is found near the surface. Limestone fossils are found in sedimentary sequences and they are old by 2.7 billion years. Sand stones with trilobites are old about 500 million years.

What are rock types?

Rocks are the major parts of the tectonic plates of earth, There are broadly three classes of rocks namely, sedimentary rocks, igneous rocks and metamorphic rocks.

Basalt is a type of well grained igneous rocks found near the surface of earth. Rapid cooling of lava rich in Mg and Ca composes Basalt rock

Limestone, a form of carbonate sedimentary rock composed primarily of calcium carbonate (CaCO3). The minerals calcite and aragonite, which are various crystal forms of CaCO3, make up the majority of its material. When these minerals separate from water that has dissolved calcium, limestone is created.

Sileous sandstone is a typical component of nearshore deposits about 500-600 million years of age. This often grades into siltstone and shale as it moves into the sea, with finer-grained sediment accumulating in deeper water to create these rocks.

Shale rocks with ammonites have an age of about 70 million years. Ammonites are spiral shaped fossilized shells of marine animals.

HNO3 + H3PO3 → NO + H₂PO4+H₂O (Acidic)
What is the complete step by step oxidation reduction reaction?

Answers

Answer:

The reaction provided is not a redox reaction. The equation shows the neutralization reaction between Nitric acid (HNO3) and Phosphoric acid (H3PO3) to produce Nitrogen monoxide (NO), Dihydrogen Phosphate (H2PO4) and water (H2O).

When two or more acids are mixed together, they can neutralize each other. This is called a neutralization reaction. The acid and the base will react to form a salt and water. In this case, Nitric acid is the acid and Phosphoric acid is the base.

The equation for this neutralization reaction can be balanced as follows:

HNO3 + H3PO3 → NO + H2PO4 + H2O

Where HNO3 = Nitric acid

H3PO3 = Phosphoric acid

NO = Nitrogen monoxide

H2PO4 = Dihydrogen Phosphate

H2O = water

The reaction is acidic in nature due to the presence of H+ ions in the products.

In summary, the reaction provided is a neutralization reaction, not a redox reaction. The equation shows that Nitric acid and Phosphoric acid neutralize each other to form Nitrogen monoxide, Dihydrogen Phosphate and water. The reaction is

Everyone was expected to show skill in using words well. Early Heian writers composed artful poems in Chinese, but as time passed, distinctly Japanese ways of writing developed both in daily life and in the creation of works of literature.Writing in Daily Life Poetry was part of daily life in Heian-kyo, and people were expected to compose poetry in public. If they could not think up a few clever lines to fit an occasion, others noticed the failure. Men and women carefully created poems to charm each other. When someone received a poem from a friend, family member, or acquaintance, he or she was expected to write one in response. The responding poem was supposed to be written in the same style and mood, and have the same imagery, as the original.In earlier times, the Japanese had used kana, which was based on simplified Chinese characters, to write the syllables of their language. In Heian times, there were two ways of writing, much like we have cursive and print letters in English. One, katakana, was more formal. Men used katakana when they wrote anything important. The second form of writing was hiragana. Characters in hiragana are formed with simple strokes that make writing and reading easier and faster. Hiragana was mostly seen as women's writing. Court women favored hiragana for personal writing, such as diaries, and some of them used it to create lasting works of literature. Over time, hiragana took its place alongside katakana as part of Japan's written language.Heian writers took care to present their work in a beautiful manner, since calligraphy skills were viewed as important as the ability to create poetry. People believed that handwriting revealed their character and goodness better than the words they used. Calligraphy was often displayed on colorful, handmade paper, and sometimes the paper was even perfumed.Women Become Japan's Leading Writers The female companions to the courtiers of Heian-kyo were usually selected for their intelligence. They often took a great interest in literature, and as a result, women led in the flowering of Japanese literature in the golden age of the 10th and 11th centuries.The best-known Heian writer was Murasaki Shikibu, often referred to as Lady Murasaki. Born into the Fujiwara family, she served as a lady-in-waiting to one of the daughters of Fujiwara Michinaga. Her novel, the Tale of Genji (GEN-jee), is a Heian masterpiece and is today considered one of the great works of world literature.The Tale of Genji is often called the world's first novel. The book follows the life of Genji, a fictional prince, and paints a vivid picture of life in the Heian court. Much of the book focuses on the thoughts and feelings of the characters, particularly the women. For this reason, the Tale of Genji has served as a model for the modern romance novel.Murasaki also kept a diary about her life in the court. Like her novel, her diary offers a close look at court life in the period.The other leading writer of the time was Sei Shonagon. Like the Tale of Genji, Shonagon's Pillow Book presents a detailed picture of life in Heian-kyo. Pillow Book is a collection of clever stories, character sketches, conversations, descriptions of art and nature, and various lists. Here is Shonagon's list of Things That Should Be Short:a piece of thread when one wants to sew something in a hurrya lamp standthe hair of a woman of the lower classesthe speech of a young girlLike Sei Shonagon, many Heian women wrote their thoughts and experiences in diaries.
