Which of the following is the correct word equation for the reaction described below? calcium hydroxide and hydrogen gas are produced by the reaction of calcium hydride and water. a.) calcium hydride + hydrogen → calcium hydroxide + water b.) calcium hydride + water → calcium hydroxide + hydrogen c.) calcium hydroxide + hydrogen → calcium hydride + water d.) calcium hydroxide + water → calcium hydride + hydrogen

Option B

Step-by-step explanation:

Given that Calcium hydroxide and hydrogen gas are produced by the reaction of calcium hydride and water.

This gives that the two substances calcium hydride and water are the inputs and they react to produce the outputs Calcium hydroxide and hydrogen gas

Inputs must appear in the chemical equation on the left side and the outputs on the right side

Hence we get the correct answer to be one which has calcium hydride and water  on left sid and Calcium hydroxide and hydrogen on the right side.

Out of 4 options only option B satisfies this fully

Hence

B.) calcium hydride + water → calcium hydroxide + hydrogen

is the right answer.
