# Producing H_{2} Gas: Na + H_{2}O Reaction

• Punkyc7
In summary, a reaction between 1.74 mol of Na and excess water will produce 1.74 mol of H2 gas at 280 K and 96 kPa. However, stoichiometric coefficients must be taken into account for accurate calculations.

1. How many liters of hydrogen gas will be produced at 280 K and 96 kPa if 1.74 of Na reacts with excess water according to the following equation.

2Na + 2H$_{2}$O $\rightarrow$2NaOH + H$_{2}$

Im gussing I am going to have to find the number of moles of H$_{2}$ before I can do anything.

So I am thinking that since there is 1.74 mol of Na that is going to be the number of moles of H$_{2}$. Is that right?

Use [noparse] and [/noparse] tags to format subscripts and superscripts (so [noparse]H3O+[/noparse] yields H3O+) - don't use inline LaTeX for formatting single characters.

You are wrong, but not far from the correct answer. You forgot to take stoichiometric coefficients into account. Please read about stoichiometric calculations.

## 1. How does the reaction between Na and H2O produce H2 gas?

The reaction between Na and H2O produces H2 gas through a process called electrolysis. This involves the breaking of bonds between the sodium (Na) and oxygen (O) atoms in water (H2O), resulting in the release of hydrogen (H2) gas.

## 2. What are the other products of the Na + H2O reaction?

In addition to H2 gas, the Na + H2O reaction also produces sodium hydroxide (NaOH) and heat. The heat is a result of the exothermic nature of the reaction, meaning that it releases energy in the form of heat.

## 3. How can I control the production of H2 gas in this reaction?

The production of H2 gas in the Na + H2O reaction can be controlled by adjusting the amount of sodium (Na) and water (H2O) used. The more sodium present, the more H2 gas will be produced. Additionally, the reaction can be sped up by using a conductive material, such as a graphite rod, to help facilitate the flow of electricity.

## 4. Is the Na + H2O reaction safe to perform at home?

The Na + H2O reaction can be dangerous if not performed properly, as it involves the use of electricity and produces flammable hydrogen gas. It is recommended to only perform this reaction under the supervision of an experienced scientist or in a controlled laboratory setting.

## 5. What are some practical applications of the Na + H2O reaction?

The Na + H2O reaction has many practical applications, such as in the production of hydrogen gas for fuel cells, in the manufacturing of sodium hydroxide (NaOH) for industrial processes, and in the purification of metals through the process of electrolysis.
