Greener Production Process of Acetylene and Calcium …

Calcium carbide (CaC2) is widely used for the production of various acetylene derivatives, accompanying with a huge amount of carbide slag waste. To develop a clean production process, we explored the reaction of CaC2 and glycerol at varying conditions for the first time. The products were characterized by various techniques. It is observed that …

Look at the equation:1 mol CaC2 and 2 mol H2O will participate in full. Or, 64 g/mol CaC2 and 36 g/mol H2O. That is like recepy when you bake a cake. You should follow this proportion, 64:36. But, in reality, it's given 128:1.8. You see, it's too little H2O and too much CaC2, which will be left over.

The heat of reaction for one mol of CaC2(s) CaC2 (s)+ 5H2O (l) = CaO (s) +2CO2 (g) + 5H2( g) is equal to 76.4 kJ. You charge 92.3 grams of CaC2 (molar mass of CaC2= 64.1 g/mol) and liquid water into a rigid container at 25°C, heat the container until the calcium carbide reacts completely, and cool the products back down to 25°C, condensing …

Limiting reactants step 4

The Balanced Equation: CaC2 + 2H20 --> Ca (OH)2 + C2H2 ; It's given that there is 100g of H20 and 100g of CaC2. 1) Divide 100g CaC2 by the molar mass of CaC2. The molar mass of CaC2 is 64.10 g/mol (found by adding Ca's mass of 40.08 to 2*12.01, where the 2 comes from the presence of 2 carbon atoms and 12.01 is carbon's mass).
