Assume you have a solution containing two volateile liquids. given the data for liquid a: mm = 13.45 g/mole, partial pressure = 1.055 atm and for liquid b: mm = 45.67 g/mole, partial pressure = 0.889 atm, what is the a: b ratio of the distillate? a. 0.35: 1 b. 3.5: 1 c. 7: 3 d. 5: 1 e. 2: 1

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.

idk what is it? is this a question that you know the answer or u dont
