15.00g of glucose is added to 250g of water at 293 k. if the vapour pressure of water at 293k is 17.535 mmHg. Calculate the lowering of vapour pressure at 293k.

Reducing agents  oxidized by the reaction 

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).
