Suppose you take a piece of hard wax from an unlit candle. after you roll the wax between your fingers for a while, it becomes soft. what state of matter is the softer wax ? is it possible for wax to change without changing state

the candle is still solidin this case, yes!

Explanation:

it is still solid because the molecules are packed together tighter than the molecules in a liquid or gas.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
