D. Water changes state when it loses or gains energy.
Explanation:
When water gains energy, it turns from ice to water, or water to gas. When water loses energy, it turns from gas to water, or water to ice.
Particles in the water move faster and create more energy when heated, and this causes them to spread wider apart and change. Particles slow down and move closer together when they get cold.
<span>When naming compounds, the first thing you need to do is decide if the compound is ionic or molecular. *Ionic compounds
will contain both metals and non-metals, or at least one polyatomic

the name will include the word acid.</span>
Data:
<span>The logarithm of number 1 on any basis will always be equal to 0, therefore:
Log10 (1) = 0

Solving:
<span>Note: For pH greater than 7 indicates that the substance is basic (pH > 7)</span>
