Chapter 8: Problem 2

\(\mathrm{CaH}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{Ca}(\mathrm{OH})_{2}+\mathrm{H}_{2}\)

Short Answer

Expert verified
In the given balanced chemical equation, calcium hydride (\(\mathrm{CaH}_{2}\)) reacts with water (\(\mathrm{H}_{2} \mathrm{O}\)) to form calcium hydroxide (\(\mathrm{Ca}(\mathrm{OH})_{2}\)) and hydrogen gas (\(\mathrm{H}_{2}\)). This is an acid-base reaction, where calcium hydride acts as a strong base and water as a weak acid. The overall process involves the transfer of protons from water to calcium hydride, releasing hydrogen gas. This reaction has practical applications such as using calcium hydride as a drying agent for gases and solvents.

Step by step solution

01

Identify the reactants

The reactants in this balanced chemical equation are calcium hydride (\(\mathrm{CaH}_{2}\)) and water (\(\mathrm{H}_{2}\mathrm{O}\)). These are the compounds that will react with each other to form new products.
02

Identify the products

After the reaction takes place, we have two products: calcium hydroxide (\(\mathrm{Ca}(\mathrm{OH})_{2}\)) and hydrogen gas (\(\mathrm{H}_{2}\)). Calcium hydroxide is a strong base while hydrogen gas is a highly reactive element.
03

Analyze the reaction

This chemical equation represents an acid-base reaction. Calcium hydride is a strong base that reacts with water (which acts as a weak acid in this case) to form calcium hydroxide (a strong base) and hydrogen gas. The overall process of this reaction can be understood as the transfer of protons (\(\mathrm{H}^{+}\)) from water to the calcium hydride, releasing the hydrogen gas.
04

Understand the practical applications

This reaction is important in various practical applications. For instance, calcium hydride is used as a drying agent for gases and solvents, as it reacts with water to produce hydrogen gas, which can then be easily removed. Additionally, this reaction demonstrates the basic properties of metal hydrides and their ability to react with water or other acids.
