Question

question 2 of 4 < points possible: 1.00 which of the following is true about the reaction between calcium and water? select one. a. calcium accepts two electrons from water. b. metal hydroxide obtained is an acid. c. the amount of hydroxide produced is determined by weighing the products. d. calcium hydroxide is produced.

Explanation:

When calcium reacts with water, the chemical reaction is $Ca + 2H_2O=Ca(OH)_2 + H_2$. Calcium is oxidized and accepts electrons from water to form calcium hydroxide and hydrogen gas. Metal hydroxides like calcium hydroxide are bases, not acids. The amount of hydroxide produced is determined by stoichiometry, not just by weighing products. And calcium hydroxide is the product formed.

Answer:

d. Calcium hydroxide is produced.
