Answer:

0.083 M

Explanation:

We'll begin by calculating the number of mole in 0.43 g of KHP (potassium hydrogen phthalate, C₈H₅O₄K). This is can be obtained as follow:

Mass of C₈H₅O₄K = 0.43 g

Molar mass of C₈H₅O₄K = (8×12) + (5×1) + (16× 4) + 39

= 96 + 5 + 64 + 39 = 204 g/mol

Mole of C₈H₅O₄K =?

Mole = mass / molar mass

Mole of C₈H₅O₄K = 0.43 / 204

Mole of C₈H₅O₄K = 0.002 mole

Next, we shall determine the number of mole of NaOH required to react with 0.43 g (i.e 0.002 mole) of KHP. This can be obtained as follow:

C₈H₅O₄K + NaOH → C₈H₄O₄KNa + H₂O

From the balanced equation above,

1 mole of KHP reacted with 1 mole of NaOH.

Therefore, 0.002 mole of KHP will also react with 0.002 mole of NaOH.

Next, we shall convert 24.11 cm³ to L. This can be obtained as follow:

1000 cm³ = 1 L

Therefore,

24.11 cm³ = 24.11 cm³ × 1 L / 1000 cm³

24.11 cm³ = 0.02411 L

Finally, we shall determine the molarity of NaOH. This can be obtained as follow:

Mole of NaOH = 0.00 2 mole

Volume = 0.02411 L

Molarity of NaOH =?

Molarity = mole /Volume

Molarity of NaOH = 0.002 / 0.02411

Molarity of NaOH = 0.083 M

Answer:

1

Explanation:

one volume of nitrogen to react

Explanation:

2,4-DNP is negative: aldehyde and ketone absent

Chromic acid is negative: alcohol absent.

KMnO4 test negative: alkene absent

The only positive result is for Fe(OH)2.

Nitro group-containing compounds react with ferrous hydroxide to give amine and ferric hydroxide red ppt. Hence given compound contains the nitro group (-NO2).

Answer:

0.95 L

Explanation:

Step 1: Given data

Concentration of the Mg(NO₃)₂ solution (C): 0.32 M (0.32 mol/L)

Mass of Mg(NO₃)₂ (solute): 45 g

Step 2: Calculate the moles corresponding to 45 g of Mg(NO₃)₂

The molar mass of Mg(NO₃)₂ is 148.33 g/mol.

45 g Mg(NO₃)₂ × 1 mol Mg(NO₃)₂ /148.33 g Mg(NO₃)₂ = 0.303 mol Mg(NO₃)₂

Step 3: Calculate the volume of solution that contains 0.303 moles of Mg(NO₃)₂

The concentration of the solution is 0.32 M, that is, there are 0.32 moles of Mg(NO₃)₂ per liter of solution.

0.303 mol Mg(NO₃)₂ × 1 L Solution / 0.32 mol Mg(NO₃)₂ = 0.95 L

Answer:

1.62x10⁻¹² M

Explanation:

HClO₃ is a strong acid, meaning that a 6.2x10⁻³ M solution has a molar concentration of H⁺ of 6.2x10⁻³.

With the above information in mind, we can calculate the pH of the solution:

Now we can calculate the pOH of the solution, using the pH:

Finally we calculate [OH⁻], using the definition of pOH:

Answer:

Your answer is D

Explanation:

Irregular galaxies do not have a regular structure.

Answer:

Li + ZnCO3

Explanation:

Li is higher than Zn on the activity series so Ln is more easily oxidized and prefers to be in a compound. For the rest of the reactions, the element that is higher on the activity series is already in the compound, so the reactions wouldn't happen.

Answer:

C. Li + ZnCO3

The more concentrated the buffer solution, the greater its buffer capacity.

An acid is any substance that in water solution tastes sour, changes blue litmus paper to red, reacts with some metals to liberate hydrogen, reacts with bases to form salts, and promotes chemical reactions.

The more concentrated the buffer solution, the greater its buffer capacity.

If the buffer capacity is 10 times larger, then the buffer solution can absorb 10 times more strong acid or base before undergoing a significant change in pH.

Hence, we need to take this into consideration when increasing either the acid or base concentration in order to increase the buffering capacity of a solution.

Answer: D Avogadro’s Number

Explanation:

Another name for a mole is Avogadro's number. option D) is correct.

What is a Mole?

A mole refers to the amount of a substance that contains as many elementary units as can be found in 12g of Carbon-12. It can also be a number of a substance /particles, such as atoms or ions. molecules or electrons.  The number of particles is approximately 6.02* 10²³ in magnitude and is called Avogadro's number of particles. it can be denoted with 'mol'.

Formula for calculating mole.

n = N/Nₐ

Where,

n = number of moles of the substance (or elementary entity)

N = total number of elementary entities in the sample

Nₐ= Avogadro constant.

Answer:

794 mmHg

Explanation:

We are going to be using the Combined Gas Law for this problem as well. Just to refresh out memory - the Combined Gas Law expresses the relationship between pressure, volume, and temperature (in KELVIN) of a fixed amount of gas. The equation itself? Right here: [tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]

Now, looking at the problem, let's assign the values to its corresponding variable:

P1 = 800mmHg; V1 = 5.0L; T1 = -50°C + 273 = 223K

V2 = 7.0L; T2 = 37°C + 273 = 310K; P2 = ?

We are looking to find the new pressure, a.k.a. P2. So, let's plug and chug the values into the equation.

Set up: [tex]\frac{(800 mmHg)(5.0L)}{223K} = \frac{(7.0L)(P_{2})}{310K}[/tex]

==> [tex]\frac{(800 mmHg)(5.0L)}{223K} * 310K = (7.0L)(P_{2})}[/tex]

==> [tex]P_{2} = \frac{(800 mmHg)(5.0L)}{223K} * \frac{310K}{7.0} }[/tex]

==> [tex]P_{2} =[/tex] 794.36 = 794 mmHg

Answer:

48 newtons

Explanation:

Answer:

The answer would be B. 1 joule/s.

Explanation:

The answer is B because the power in general is normally defined as energy over time. Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s.

Another reason why it's B is because I had the same exact question in class, I took a screenshot of it a day ago:
