Consider the balanced equation below.

wolverine [178]

Answer:

a) H2S:SO2 = 2:2 and O2:H2O = 3:2

Explanation:

2H2S + 3O2 → 2SO2 + 2H2O

⇒ H2S:SO2 = 2 mol H2S / 2 mol SO2 ≡ 2 : 2

⇒ O2:H2O = 3 mol O2 / 2 mol H2O ≡ 3 : 2

Azurite, 2 CuCO3 * Cu(OH)2 is blue and malachite, CuCO3 * Cu(OH)2 is green. Which contains the higher percentage of copper? Each

blagie [28]

Answer:

Malachite green has highest percentage of copper.

Explanation:

Azurite: $2CuCO_3.Cu(OH)_2$

Molar mass of Azurite = M = 344.67 g/mol

Atomic mass of copper = 63.55 g/mol

Percentage of copper in Azurite :

$Cu\%=\frac{3\times 63.55 g/mol}{344.67 g/mol}\times 100=55.31\%$

The percentage of copper in an azurite is 55.31%.

Malachite: $CuCO_3.Cu(OH)_2$

Molar mass of Malachite = M = 221.12 g/mol

Atomic mass of copper = 63.55 g/mol

Percentage of copper in Malachite:

$Cu\%=\frac{2\times 63.55 g/mol}{221.12 g/mol}\times 100=57.48\%$

The percentage of copper in an malachite is 57.48%.
