Question

For the reaction represented by the equation 2H2 + O2 2H2O, how many moles of water can be produced from 6.0 mol of oxygen?

a. 2.0 mol
b. 6.0 mol
c. 12 mol
d. 18 mol

Answer 1

Answer:

C. 12 mol H2O


Step-by-step explanation:

2 mol H20
6.0 mol O2 • ——————
1 mol O2

= 12 mol H2O

Answer 2

To produce moles of water from moles of oxygen in the given reaction, we can use the stoichiometry of the reaction and set up a ratio. By multiplying the given moles of oxygen by the appropriate ratio, we can calculate the moles of water produced. The correct answer is 12 mol.

Step-by-step explanation:

To determine the number of moles of water produced from 6.0 mol of oxygen in the reaction 2H2 + O2 → 2H2O, we can use the stoichiometry of the reaction.

The balanced equation shows that 1 mole of O2 reacts to produce 2 moles of H2O. Therefore, to calculate the number of moles of water produced, we can set up the following ratio:

1 mol O2 : 2 mol H2O.

Since we have 6.0 mol of oxygen, we can use the ratio to calculate the number of moles of water produced:

6.0 mol O2 × (2 mol H2O / 1 mol O2) = 12 mol H2O.

Therefore, the correct answer is option c. 12 mol.
