ch3ch2ch2ch2ch2oh + h2so4 --> ch3ch2ch2ch=ch2 + h2o

It is a dehydration reaction.

Explanation:

Dehydration reaction is a type of reaction to yield unsaturated compounds. In the process a water molecule (H2O) is released and a double or triple bonds between two carbon atoms is formed.

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

cu2o
