Zinc reacts with water to produce zinc hydroxide and hydrogen gas. What is the equation for this reaction?
To get this chemical equation, all you have to do is reference the question because it already gives you all of the compounds you need.
To get the formula for zinc (II) hydroxide, you need to know that hydroxide has a 1- charge and you need 2 of them to cancel out zinc's 2+ charge.
Hydrogen gas is a diatomic molecule from the mnemonic Br I N Cl H O F.
