Question 1

Carbonic acid can form water and carbon dioxide upon heating. How much carbon dioxide is formed from 6.20 g of carbonic acid?

H2CO3 → H2O + CO2

◦ 2.20 g
◦ 8.80 g
◦ 6.20 g
◦ 4.40 g

Question 2

Determine the theoretical yield of H2S (in moles) if 4.0 mol Al2S3 and 4.0 mol H2O are reacted according to the following balanced reaction. A possibly useful molar mass is Al2S3 = 150.17 g mol-1.

Al2S3(s) + 6H2O(l) → 2Al(OH)3(s) + 3H2S(g)

◦ 6.0 mol H2S
◦ 18 mol H2S
◦ 4.0 mol H2S
◦ 12 mol H2S
◦ 2.0 mol H2S
