The recommended calcium intake for teenagers is 1300 mg per day. a glass of milk contains 305 mg of calcium. one glass contains a volume of 8 fluid ounces. how many liters of milk should a teenager drink per day to get the recommended amount of calcium? one fluid ounce equals 29.6 ml

the millers tale is the answer.

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.
