Wax melts when it is heated. Which most likely describes what is true of the result of this reaction? The bonding of the atoms is not the same before and after the change. The wax has the same density before and after the change. The same amount of wax exists before and after the change. The wax cannot be changed back into a solid.

The same amount of wax exists before and after the change.

Explanation:

The melting of wax is a physical change and not a chemical change. During a physical change, no new substance is formed as chemical reactions do not take place. In a chemical change, however, new substances are formed because chemical reactions do take place.

In addition to that, both physical and chemical changes obey the law of conservation of matter which states that matter can neither be created nor destroyed but can be transformed from one form to another. It also entails that the mass of a substance present before a reaction should be equal to the mass obtained after the reaction.

In this case, the candle just simply changed its state from solid to liquid. This means that the total mass of the candle that existed as a solid will be the same as that of the liquid state.

The answer is C). The same amount of wax exists before and after the change.

Explanation:

The reason for this is simple. If you put a block of wax in a pan, and put it on the scale, (lets say it weighs 2 pounds) it will way two pounds. If you stick it on a stove, and it melts, does it weigh the same amount? Yes, it does. This is because none of the wax left the pan. It just moved around. The only difference is that it is a liquid. It still has the same amount of wax.

Hope this helps!
