Answer: The correct answer is Option A.

Explanation:

Mole ratio is defined as the ratio between the stoichiometric coefficients of the molecules present in the chemical reaction.

For the given balanced chemical equation:

$3Fe+4H_2O\rightarrow Fe_3O_4+4H_2$

By Stoichiometry of the reaction:

3 moles of iron metal reacts with 4 moles of water to produce 1 mole of iron oxide and 4 moles of hydrogen gas.

The mole ratio of $Fe_3O_4:Fe=1:3$

Hence, the correct answer is Option A.

Answer:

A- 1:3

Explanation:

Mole ratio is the ratio between the amount (In moles) of two substances involved in a chemical reaction.

For the reaction:

3Fe + 4H₂O → Fe₃O₄ + 4 H₂

There is 1 mole of Fe₃O₄ per 3 moles of Fe. In other words, the mole ratio of Fe₃O₄ to Fe is 1:3. Thus, answer is:

A- 1:3

What is the maximum number of moles of Al2O3 that can be produced by the reaction of .4 mol of Al with .4 mol of O2

Darya [45]

Given:

Moles of Al = 0.4

Moles of O2 = 0.4

To determine:

Moles of Al2O3 produced

Explanation:

4Al + 3O2 → 2Al2O3

Based on the reaction stoichiometry:

4 moles of Al produces 2 moles of Al2O3

Therefore, 0.4 moles of Al will produce:

0.4 moles Al * 2 moles Al2O3/4 moles Al = 0.2 moles Al2O3

Similarly;

3 moles O2 produces 2 moles Al2O3

0.4 moles of O2 will yield: 0.4 *2/3 = 0.267 moles

Thus Al will be the limiting reactant.

Ans: Maximum moles of Al2O3 = 0.2 moles

If you had a 0.800 L solution containing 0.0240 M of Fe3+(aq), and you wished to add enough 1.38 M NaOH(aq) to precipitate all o

guapka [62]

Answer:

0.041 L = 41.3 mL

Explanation:

This problem we will solve by considering the stoichiometry of the reaction and the definition of molarity.

Number of moles in .800 L solution:

0.800 L x 0.0240 M = 0.800 L x .0240 mol/L = 0.0192 mol Fe³⁺

to form the precipitate Fe(OH)₃ we will need 3 times .0192

mol NaOH required = 0.057

given the concentration of 1.38 mol M NaOH we can calculate how many milliliters of NaOH will contain 0.057 mol:

1.L/1.38 mol NaOH x 0.057 mol NaOH = 0.041 L

0.041 L x 1000 mL/1L = 41.3 mL

The human activity creating water pollution and depletion are uses of fertilizers, detergents and chloro flouro carbon many other things.

<h3>What is water pollution?</h3>

Water pollution is defined as the contamination of water bodies, usually as a result of human activity, in such a way that their lawful uses are harmed.

The activities of human that creating water pollution are:

Uses of fertilizers
Harmful chemical in agriculture
Detergents for washing clothes
Wastes from industries

And depletion in the ozone layer are due to halogen source gases, which contain chlorine and bromine atoms, are produced by human activities. These emissions into the atmosphere eventually contribute to ozone depletion in the stratosphere.

Hence human activities are uses of fertilizers, detergents and many other things.
