How many grams of nitric acid, HNO3, are required to neutralize (completely react with) 4.30g of Ca(OH)2 according to the acid-base reaction: 2HNO3(aq) + Ca(OH)2(aq) → 2H2O(l) + Ca(NO3)2(aq)
A 3.00- g sample of an alloy of Pb Lead was dissolved in nitric acid (HNO). Sulfuric acid was added to this solution, which precipitated 1.69 g of lead sulfate (PbSO.). What is the percentage of lead (Pb) in the sample? (Given the atomic mass of Pb - 207, S =32,0 - 16 gram/mole)
Concentrated nitric acid reacts with solid copper to give nitrogen dioxide gas and dissolved copper ions according to the equation: Cu(s) + 4 H+(aq) + 2 NO3 - (aq) → 2 NO2(g) + Cu2+(aq) + 2 H2O(l) Suppose that 6.80 g of copper is consumed in this reaction and that the NO2 is collected at a pressure of 0.970 atm and a temperature of 45 oC. What volume of NO2 is produced?
