Which balanced equation represents a chemical change? a. h2o(l) → h2o(s) + energy b. 2 h2o(l) + energy → 2 h2(g) + o2(g) c. h2o(g) → h2o(l) + energy d. h2o(l) + energy → h2o(g)

Okay, so what you first do with this  type of question is think about what a chemical change is. A chemical change is a change that can not be reversed. A physical change is something that can be reversed or done using temperature. e.x. Water freezing into ice is a physical change, where as combining vinegar and baking soda together releases a gas, which is chemical, or iron rusting in the presence of oxygen.  Which one of these equations has one chemical molecule set that produces a different set?

yes

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.
