Answer:

C. One mole of water was produced from this reaction.

Explanation:

  • From the balanced equation:

<em>2H₂ + O₂ → 2H₂O,</em>

It is clear that 2 mol of H₂ react with 1 mol of O₂ to produce 2 mol of H₂O.

  • So, if one mole of hydrogen was used in this reaction:

1/2 mol of O₂ was used in the reaction, and

1 mol of water was produced from this reaction.

  • So, the correct statement is:

<em>C. One mole of water was produced from this reaction. </em>

Answer:

The correct answer is option C.

Explanation:

2H_2+O_2\rightarrow 2H_2O

If 1 mole of hydrogen is used. For that divide the whole equation with '2'.

\frac{2}{2}H_2+\frac{1}{2}O_2\rightarrow \frac{2}{2}H_2O

H_2+\frac{1}{2}O_2\rightarrow H_2O

When 1 mole of hydrogen reacts with half mole of oxygen it gives 1 mol of water.

So, from the given options the correct answer is option C.

How is an exothermic reaction identified on a potential energy diagram?
Alla [95]
Energy diagrams are use to depict the energy changes that occur during a chemical reaction. There are two types of reaction based on the energy change, these are exothermic and endothermic reactions. In endothermic reactions energy are gained while in exothermic reactions energy are lost to the environment. To identify an exothermic reaction on a potential energy diagram, one has to compare the potential energy of the reactants and the products. If the potential energy of the product is less than that of the reactants, the reaction is exothermic.
