WATER, WATER EVERYWHERE: It takes approximately 120 L of water to produce one 1.3-L can of fruit juice. It takes about 450 L of water to place one fried egg on your breakfast plate. Think of possible explanations for these two facts by listing the steps involved in producing and delivering to your home the fruit juice and the egg. Then review each step and consider where water use would occur.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
