Determine the total moles of N, (g) + 6 HCI (g) gas in the container after the reaction has gone to completion.Calculate the theoretical yield of NaOH when 4.0 g of Na2O2 reacts with excess water according to the expression: Na2O2 + 2H2O ---> H2O2 + 2NaOH
- Give the empirical formula of an oxide of lead that contains 90.65% Pb.The goal of the first part of the experiment is to determine the value of n in the formula for sodium percarbonate, Na2CO3·n H2O2. This will not be a whole number as sodium percarbonate is a non-stoichiometric compound. Titration of a 25.0 mg sample of sodium percarbonate revealed that it contains 0.224 millimoles of hydrogen peroxide. Using this amount, the molar masses of hydrogen peroxide and sodium carbonate, and the law of conservation of mass, determine the value of n implied by this data.Silver carbonate is an essential substance used in microelectronics. Calculate the percent by mass of silver (Ag) found in silver carbonate (Ag2CO3).
