The reaction equation is already balanced. So the mole ration of reactants and production is the ratio of the coefficients. So the mole ratio of N2 to NO2 is 1:2.
Answer:
You should not use an open flame to heat the solvent and the solvent should be heat in a stoppered flask to vapour away from the open flame
Explanation:
Answer:
1.605cm = 4 significant figures
16.050cm = 4 significant figures
16.050cm = 4 significant figures
12 + 12.5 + 125 = 149.5 = 4 significant figures
1.62 × 10^3/2.8 × 10^-5 = 1620/0.000028 = 11 significant figures
