Using the balanced equation
3Ba+Al2(SO4)3-->2A1+3BaSO)
if 1 g of Ba reacts with 1.8 g Al2(SO4)3, what is the excess reactant?

you should just be yourself and not let any body tell you other wise.

explanation:

why?

because if they don't love you for your self then they don't deserve you.

b) nuclear ive learned that in a pedtrodic table

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
