Transcribed Image Text:Aluminum reacts with aqueous sodium hydroxide to
produce hydrogen gas according to the following
equation:
2Al(s) + 2NAOH(aq) + 6H2O(1)2NAAI(OH)4(aq) +
3H2(g)
The product gas, H2, is collected over water at a
temperature of 20 °C and a pressure of 741 mm Hg. If the
wet H2 gas formed occupies a volume of 6.38 L, the
|mol. The
number of moles of Al reacted was |
vapor pressure of water is 17.5 mm Hg at 20 °C.
Transcribed Image Text:Oxygen gas can be prepared by heating potassium
chlorate according to the following equation:
2KCIO;(s)2KCI(s) + 302(g)
The product gas, O2, is collected over water at a
temperature of 20 °C and a pressure of 751 mm Hg. If the
wet O2 gas formed occupies a volume of 9.94 L, the
number of grams of O2 formed is [
g. The vapor
pressure of water is 17.5 mm Hg at 20 °C.
