Balance the following equations (show you process): (a) Cu(s)+HNO₂(aq) → Cu(NO)2(aq) + H2O(l) +NO(g) (b) (NH) Cr₂O(s) → Сг₂O̟(s) + N2(g) + H₂O(g) (c) HPO (aq)+ Ca(OH)2(s) Ca (PO)₂(s) + H₂O(1)

The carbon dioxide exhaled in the breath of astronauts is often removed from the spacecraft by reaction with lithium hydroxide 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) Estimate the grams of lithium hydroxide required per astronaut per day. Assume that each astronaut requires 2.50 103 kcal of energy per day. Further assume that this energy can be equated to the heat of combustion of a quantity of glucose, C6H12O6, to CO2(g) and H2O(l). From the amount of glucose required to give 2.50 103 kcal of heat, calculate the amount of CO2 produced and hence the amount of LiOH required. The H for glucose(s) is 1273 kJ/mol.

Write a balanced equation for the reaction of hydroiodic acid, HI, with calcium hydroxide, Ca(OH)2. Then, write the balanced complete ionic equation and the net ionic equation for this neutralization reaction.
