Answer:

7.97 moles

Explanation:

The number of moles (n) of iron (Fe) in this question can be calculated by dividing its number of atoms by Avogadro's number (6.02 × 10²³ atoms).

That is;

n = number of molecule ÷ Avogadro's number

According to this question, the number of atoms of Fe is given as 4.8 x 10²⁴ atoms.

Hence,

n = 4.8 x 10²⁴ ÷ 6.02 × 10²³

n = 4.8/6.02 × 10^(24-23)

n = 0.797 × 10¹

n = 7.97 moles

the mercury would be lowest at location 4.

Explanation: this is because pressure and altitudes have inverse relationship at the troposphere. higher altitude has lower pressure. also pressure at location 4 contribute to pressure at location 1. but pressure at location 1 do not contribute to pressure at location 4.

Answer:

The compound with the correct formula is;

A. MNO₃

Explanation:

The number of oxidation states in the metal, M = One oxidation state

The formula of the compound formed by the metal, M = MHCO₃

We note that the ion HCO₃⁻, known as hydrogen carbonate has an oxidation number of -1

Similarly nitrate, NO₃⁻ has an oxidation number of -1, therefore, the metal M can form similar compound formed with HCO₃⁻ with nitrate, and we have;

The possible compounds formed by the metal 'M' includes MHCO₃ and MNO₃.

Answer:

You can make 149.1g of KCl

Explanation:

1 mole of potassium chloride, KCl, contains 1 mole of potassium, K. That means, with 2.000 moles of K we can make 2.000 moles of KCl. To solve this question we must convert these moles of KCl to mass in grams using its molar mass (Molar mass KCl = 74.5513g/mol):

Mass KCl:

2.000 moles KCl * (74.5513g / mol) =

Answer: The  volume is 57.52 mL if the temperature if raised to 343K.

Explanation:

Given: [tex]V_{1}[/tex] = 27 mL,       [tex]T_{1}[/tex] = 161 K

[tex]V_{2}[/tex] = ?,        [tex]T_{2}[/tex] = 343 K

According to Charles law, at constant pressure the volume of an ideal gas is directly proportional to temperature.

Formula used is as follows.

[tex]\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}\\\frac{27 mL}{161 K} = \frac{V_{2}}{343 K}\\V_{2} = 57.52 mL[/tex]

Thus, we can conclude that volume is 57.52 mL if the temperature if raised to 343K.

Answer:

Solution A is 1,000 times more acidic than Sol. B

Explanation:

for pH values we use scientific notation:

-log10 c (where c is the hydrogen ion concentration) is used to notate pH value (think of it as a unit)

ie:

10^-2 is sol A 10^-5 is sol B

5-2 is 3

10^-3 = 1000

there's a diff of 1,000 between the solutions.

The acidity or alkalinity of a solution depends on the hydronium ion concentration and hydroxide ion concentration. Here the solution A of pH 2.0 is more acidic than the solution of pH 5.0.

The pH of a solution is defined as the negative logarithm to the base 10 of the value of the hydronium ion concentration in moles per litre. When the pH of the solution is less than 7 it is acidic whereas when pH is greater than 7, it will be basic.

The pH of the solution is calculated by the equation:

pH = - log [H₃O⁺]

Then the concentration of H₃O⁺ is:

[H₃O⁺] = 10⁻pH

At pH = 2.0, [H₃O⁺] = 10⁻² = 0.01

At pH = 5.0, [H₃O⁺] = 10⁻⁵ = 0.00001

Thus here the Solution A is 1,000 times more acidic than Solution B.

Answer:

3.36 dm³

Explanation:

STP: Means Standard temperature and pressure.

According to Avogadro's Law, it states that the molar volume of every gas is the volume occupied by one mole of that gas at stp and is equal to 22.4 dm³

From the question,

1 mole of Nitrogen gas (N₂)  occupies a volume of 22.4 dm³

But,

1 mole of nitrogen gas has a mass of 28 g

Therefore,

28 g of nitrogen gas occupies a volume of 22.4 dm³,

Then,

4.2 g will occupy a volume of X dm³

X = (22.4×4.2)/28

X = 3.36 dm³

Answer:

10.1 M

Explanation:

Applying,

pH = -log(H⁺).................... Equation 1

But,

[H⁺][OH⁻] = 1×10⁻¹⁴................ Equation 2

Where [H⁺] = Hydrogen ion concentration, [OH⁻] = Hydroxyl ion concentration.

From the question,

Given: [OH⁻] = 1.25×10⁻⁴ M

Substitute into equation 2

[H⁺][1.25×10⁻⁴] = 1×10⁻¹⁴

[H⁺] = 1×10⁻¹⁴/1.25×10⁻⁴

[H⁺] = 0.8×10⁻¹⁰ M

[H⁺] = 8×10⁻¹¹ M

Also, Substitute the value of [H⁺] into equation 1

pH = -log[8×10⁻¹¹]

pH = 10.1 M

Answer: The pH of given solution is 2.3

Explanation:

It is given that the concentration of HCl solution is 0.005 M.

pH is the negative logarithm of concentration of hydrogen ions.

[tex]pH = -log [H^{+}][/tex]

Substitute values into the above formula as follows.

[tex]pH = -log [H^{+}]\\= - log (0.005)\\= 2.3[/tex]

Thus, we can conclude that the pH of given solution is 2.3

Answer:

A

Explanation:

A catalyst speeds up a reaction by lowering the required activation energy, so it's not B. Like previously stated, the catalyst lowers the activation energy required, so it's not C either. This leaves us with A. Just to double check, does a catalyst speeds up a reaction? Yes! So like it says in A, a catalyst causes the equilibrium to be reached faster. Have a nice day! :)

Catalysts speed up a chemical reaction by causing equilibrium to reach quickly while maintaining the equilibrium's position. Thus, option A is true.

A catalyst increases the reaction rate by decreasing the activation energy of the reaction. As the minimum energy required by the reactants for the reaction is decreased the rate of the formation of products increases.

During the reaction, the catalyst remains unchanged and does not undergo any chemical change. It can increase the reaction rate of both irreversible and reversible reactions.

In an equilibrium reaction, the catalyst can increase the rate of both forward and reverse reaction by reaching the reaction equilibrium at a faster rate and can move the reaction toward the products as well as a reactant.

Therefore, the catalyst causes equilibrium to be reached faster.

Answer: The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides

Explanation:

The moon's gravity affects the oceans nearest the moon because the moon's gravity pulls water into a tidal bulge is a true statement.

The tidal force is the result of the moon's gravitational pull.

The tidal force causes Earth—and its water—to bulge out on its closest and furthest sides from the moon. High tides cause these water bulges.

Thus, the statement is correct.
