The answer is A, because of the chemical reaction taking place color can change (as in this case). Hope it helps!
Salt dissolving in a glass of water, using electricity to break down water into hydrogen and oxygen, rust forming on an iron fence and gas burning on a stove.
Answer:
Boiling - when the liquid is heated to a gas.

Answer:
Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.
Answer:
92.6
Explanation:
6 mol x 18.02 g of H2o --> 3 mol x 58.33 g Mg(OH)2
108.12 g of h2o --> 174.99 of Mg(OH)2
g of H2O is 150 g of Mg(OH)2
150g x 108.12g / 174.99 =
92.67
