Question

sodium (NA) and water (H2O undergo a chemical reaction that produces sodium hydroxide (NaOH) and hydrogen gas (H2). Which equation represents this chemical reaction

Answer 1

There are no options in this question, however, the equation can be provided. The answer is:

2Na + 2H2O --> 2NaOH + H2

Step-by-step explanation:

This question is deacribing the equation between sodium (Na) and water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The equation originally is as follows:

Na + H2O --> NaOH + H2

From the above equation, one would notice that it is not balanced because the number of atoms of each element is not the same on both sides of the equation. Hence, to balance the equation, a coefficient is used to make sure the same number of atoms of each element are on both sides.

We have;

2Na + 2H2O --> 2NaOH + H2
