Chemistry

1. Some commercial drain cleaners contain a mixture of sodiumhydroxide and aluminum powder. When the mixture is poured down aclogged drain, the following reaction occurs: 2NaOH(aq) + 2Al(s) +6H2O(l) → 2NaAl(OH)4(aq) + 3H2(g) The heat generated in thisreaction helps melt away obstructions such as grease, and thehydrogen gas released stirs up the solids clogging the drain.Calculate the volume of H2 formed at 25.5°C and 1.00 atm if 3.75 gof Al is treated with an excess of NaOH.

2. When ammonium nitrite (NH4NO2) is heated, it decomposes toliquid water and nitrogen gas. This property is used to inflatesome tennis balls. (a) Write a balanced equation for the reaction.Include phase symbols. NH4NO2(s) → ___ (b) Calculate the quantity(in grams) of NH4NO2 needed to inflate a tennis ball to a volume of74.59 mL at 1.63 atm and 22°C. Assume the volume of water producedis negligible.
