The percent of SO₂ in H₂SO₄ : 65.3%

Proust states the Comparative Law that compounds are formed from elements with the same Mass Comparison so that compounds have a fixed composition of elements

%Mass A in AxBy =  

[tex]\tt \dfrac{x.Ar~A}{MW~A_xB_y}\times 100\%[/tex]  

For SO₂ in H₂SO₄ :

MW SO₂ = 32 + 2.16=64 g/mol

MW H₂SO₄ =2.1+32+4.16=98 g/mol

The percent of SO₂ :

[tex]\tt \dfrac{64}{98}\times 100\%=65.3\%[/tex]

Answer: 2

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]

[tex]\text{Moles of} Fe_3O_4=\frac{275g}{233.5g/mol}=1.18moles[/tex]

[tex]3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)[/tex]  

According to stoichiometry :

1 mole of [tex]Fe_3O_4[/tex] are produced by = 4 moles of [tex]H_2O[/tex]

Thus 1.18 moles of [tex]Fe_3O_4[/tex] will be produced by=[tex]\frac{4}{1}\times 1.18=4.72moles[/tex]  of [tex]H_2O[/tex]

Mass of [tex]H_2O=moles\times {\text {Molar mass}}=4.72moles\times 18g/mol=85.0g[/tex]

Thus 85.0  g of [tex]H_2O[/tex] will be required and 2 steps are required to get the answer.

Answer:

Explanation:

conversion factor is used to make sure that all the units cancels with the other units and we only remain with the mass of Ag I which is 51.2g but since the number of moles can be calculated by dividing with the relative molecular mass therefore 51.2g/234.7gmol=0.22mol

1. solute is the substance that is being dissolve,while solvent is dissolving medium

2.saturated is solution that contain maximum amount of solut that capable of being dissolve and supersaturated is solution that contain less amount or medium of solut that capable being dissolve : example vinger

3. is a number placed in front of a chemical symbol or formula. It shows how many atoms or molecules of the substance are involved in the reaction. For example, two molecules of hydrogen would be written as 2 H2, and two molecules of water would be written 2 H2O . yes it's can be change only in caseWhen you balance an equation you can only change the coefficients

Answer:

Convection currents are a circular current caused by the difference in temperatures from the bottom to the top of the mantle. It is because of these currents that the plates of the Earth have moved in the past and are moving today. These plate movements cause earthquakes, mountain building, and volcanism.

Explanation:

When halogens react with metals,they form salts called metal halides according to their electronic configuration according to which reaction takes place.

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Answer:

130.5g

Explanation:

At the of the reaction, the combined mass of X and Y will be 130.5g.

The premise for this conclusion is based on the law of conservation of matter.

This law states that "in a chemical reaction, matter is neither created nor destroyed but changed from one form to another".

In essence, in a chemical reaction, there is no mass loss.

Explanation:

Given that acetylene gas reacts with oxygen to produce caobon dioxide, water and heat and the unbalnced equation is

[tex]C_2H_2(g)+O_2(g) \rightarrow CO_2(g) + H_2O(g)+ heat[/tex]

Gram-formula mass of [tex]C_2H_2= 26[/tex] g/mol

So, mass of 1 mole of acelylene is 26 grams

Therefore, mass of 25 moles of acelylene=25x26=650 grams

Hence, the mass of 25 moles of acelylene is 650 grams

The mass of 25 moles of acetylene has been 0.65 kg.

Moles are the count of a number of molecules in an entity and the mass based on the formula mass. 1 mole of a substance has [tex]\rm 6.023\;\times\;10^2^3[/tex] molecules.

The moles can be calculated as:

Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]

Given, mole of acetylene = 25 mol

molecular mass of acetylene = 26 g/mol

Mass of acetylene = moles [tex]\times[/tex] molecular weight

Mass of acetylene = 25 [tex]\times[/tex] 26

Mass of acetylene = 650 grams

1000 grams = 1 kg

650 grams = 0.65 kg.

The mass of 25 moles of acetylene has been 0.65 kg.

Explanation:

The classic rainbow is made of certain colors, so If a white light passed through a glass prism [and only glass] the rainbow would show because of the colors bending [the naked eye can't see that 0-0]

Also, you know the sky is blue right??  The color blue in that prism when the light shined over was the shortest and wavy color. each color has it's own wave. blue is just the shortest and waviest one.

Answer:

Stove → Pot = conduction, Pot → Egg = convection.

Explanation:

There are three ways in which heat is being transferred from one medium to the other and the means are; radiation, conduction and convection heat transfer.

Radiation is the process in which heat is being transferred through emission in form of electromagnetism. Conduction heat transfer Is the process in which heat is being transferred through contact that is two bodies touching each other. Convection heat transfer is the kind of heat that happens through gases.

Since the heat from the stove touching the pot is the conduction heat transfer.

After the water has been heated up, the gas from the water makes the convection heat transfer.
