1) Explain what is the mass of the solid NH4Cl formed when 76.0 g of NH3 are mixed with an equal mass of HCl?
2) A piece of sodium metal reacts entirely with water as follows.
2 Na(s) + 2 H2O(l) 2 NaOH(aq) + H2(g)
If the hydrogen gas generated is collected over water at 25.0°C. The volume of the gas is 420mL measured at 1.00atm. Compute the number of grams of sodium used in the reaction. Vapor pressure of water at 25°C = 0.0313atm.
