CrO2 + n2 + H2 + H2O = no reaction: no such compound CrO2

CrO3 + NH3 + H2O = Cr(OH)3-precipitate +N2 + H2O

Cr2O3 + N2 + H2O = no reaction

Answer the following:
How many mols in 52 g of C2H2? - divide by mol weight
How many mols of CO2 will form? look at the equation
How many grams of CO2 will be produced? multiply mols of CO2 to molecular weight (44)

surface, I understand, sodium hydroxide is the most common, but not very good in this case. It's not so much about NaOH, but water that is not a good solvent in this case. Hydroxy groups of dextran will be "lost" in water. I'd recommend non-aqueous polar solvent such as DMF and soluble str...
