Answer 2

Ответ:

Ca + 2H2O = Ca(OH)2 + H2

Answer 3

It seems like there might be a typo in the chemical equation you provided. The correct balanced equation for the reaction between calcium (Ca) and water (H2O) to form calcium hydroxide (Ca(OH)2) and hydrogen gas (H2) is as follows:

Ca + 2H2O → Ca(OH)2 + H2

Here's how the equation is balanced:

1. Calcium (Ca) is already balanced on both sides.
2. Hydrogen (H) is balanced on both sides with 2 atoms on each side.
3. Oxygen (O) is balanced with 2 atoms on the left side (2 in water) and 2 atoms on the right side (1 in calcium hydroxide and 1 in hydrogen gas).

The balanced equation shows that one calcium atom reacts with two water molecules to produce one molecule of calcium hydroxide and one molecule of hydrogen gas.
