Question

Name Worksheet E Page 5 of 5 57) Formation of ammonia (g) from its elements 58) Complete oxidation of methane (g) to produce carbon dioxide (g) and water 59) Complete oxidation of hydrogen sulfide (g) to produce sulfur dioxide (g) and water 60) Incomplete oxidation of hydrogen sulfide (g) to produce sulfur (s) and water 61) Potassium dichromate solution reacts with Irom (D sulfate solution in sulfturic acid to form chromium (I) sulfate solution iron(III) sulfate solution and water. 62) Copper metal reacts with nitric acid to provide copper (Il) nitrate solution nitrogen monoxide gas and water. 63) Potassium permanganate solution reacts with sodium oxalate solution in potassium hydroxide solution to generate manganese dioxide solid, potassium carbonate solution, sodium carbonate solution and water. 64) Sodium bismuthate solid reacts with manganese (I) nitrate solution in nitric acid to generate sodium permanganate solution, bismuthism (III) nitrate solution, sodium nitrate solution and water

Explanation / Answer

57

ammonia = NH3

elements = N,H

elemetnal states

N2(g) + H2(g) = NH3(g)

balance

N2(g) + 3/2H2(g) = NH3(g)

Q58

oxidation of methane

CH4(g) + O2(g) = CO2(g) + H2O(l)

balance H, O

CH4(g) + O2(g) = CO2(g) + 2H2O(l)

CH4(g) + 2O2(g) = CO2(g) + 2H2O(l)

Q59

oxidation of H2S(g)

H2S(g) + O2(g) = SO2(g) + H2O(l)

balance H, then O

H2S(g) + 3/2O2(g) = SO2(g) + H2O(l)

Q60

incopmlete ox. of H2S to S an dwater

H2S + O2 = S + H2O

balance O

H2S + 1/2O2 = S + H2O
