How many grams of HCl, are needed to produce 125 ml of carbon dioxide gas at STP in the following reaction? CaCO3(s) + 2 HCl(aq) - -> CaCl(aq) + CO2(g) + H20(1) In a reaction similar to this laboratory experiment, 0.625 g of aluminum metal was completely consumed and the H, gas collected over water at 55.0°C and atmospheric pressure of 759 mm Hg. What was the volume of H, gas produced? (Be sure to correct H2...
How many moles of H2 can be produced from x grams of Mg in magnesium-aluminum alloy?
A 0.250-g sample of a magnesium-aluminum alloy dissolves completely in an excess of HCl(aq). When the liberated H2(g) is collected over water at 29 degrees Celsius and752 torr, the volume is found to be 301 mL. The vapor pressure of water at 29 degrees Celsius is 30.0 torr.How many moles of H2 can be produced from x grams of Mg in magnesium-aluminum alloy? The molar mass of Mg is 24.31 g/mol.Express your answer in terms of x to four decimal...
