Answer 1

Answer:

1. Hence, the growth of nationalism in the colonies is linked to an anti-colonial movement. ... In the process of their struggle with colonialism people began discovering their unity. Anti-colonial movement gave a strong issue to the people with which they could identify and could come on a common platform.Mar 5,20g of Al = 20/26.98 mol = 0.74 mol
2. 30g of S = 30/32.07 mol = 0.94 mol
4. so, only min(.74/2,.94/3) = 0.31333 mol of Al2S3 can be formed:
6. .31333 mol Al2S3 = .61667*26.98g Al + .94*32.07 g S = 16.64g Al + 30g S
8. That leaves 3.36g Al unreactedrfgd the first one is the
