1. How many moles of sodium are required to produce 40. grams of NaOH?
2. How many grams of NaOH are produced with the reaction of 5.00 moles of water?
3. How many grams of H₂ are produced with the reaction of 36 grams of water?

Ans() ; the burning of them contributes to global warmingthey come from decayed organic material;

Answer is: hydrogen is being oxidized.chemical reaction: co₂ + h₂ → co + h₂o.oxidation half reaction: h₂ → 2h⁺ + 2e⁻.reduction half reaction: c⁺⁴ + 2e⁻ → c⁺².oxidation is increase of oxidation number, hydrogen change oxidation number from neutral charge (in molecule of hydrogen) to oxidation number +1 (in water).
