When a block of steel at 90 degrees celsius is placed in a bucket of water at 30 degrees celsius, what happens? question 22 options: the temperature of the steel increases and the temperature of the water decreases. the temperature of the steel increases and the temperature of the water increases. the temperature of the steel decreases and the temperature of the water decreases. the temperature of the steel decreases and the temperature of the water increases.

catya that's not even a b or c

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
