CaC2 (s) + 2 H2O (l) ----> C2H2 (g) + Ca(OH)2 (aq) When 44.5 g of calcium carbide is reacted with 100.0 g of water, how much acetylene is produced? 2. If 15.8 g of acetylene is produced, what is the percent yield?
arcording to the reaction below. 1. Calcium carbide (CaC2) reacts with water to produce acetylene (C2H2) according to the reaction below CaC2(s) + 2H20()Ca(OH)2(s) + C2H2(g) A certain mass of CaC2 reacts completely with water to give 64.5 L of acetylene at 50.0 °C and 1.00 atm. If the same mass of calcium carbide reacts completely at 400.0 °C and 1.00 atm, what volume of acetylene will be produced? a. 31.0 L b. 516 L c. 8.06 L d. 134...
In an experiment solid calcium carbide (CaC2) is combined with water (two hydrogens and one oxygen) in a balloon and tied off. Soon the balloon expands as gaseous acetylene (two carbons and two hydrogens) and solid calcium hydroxide (Ca(OH)2] form. OBSERVATIONS: . . . Mass of solid calcium carbide added to balloon: 0.800 g Mass of water added to balloon: 2.10 g Mass of balloon (by itself): 4.90 g Observations after initial mixing: The solid white calcium carbide seems to...

What is a balloon volume? View calculations 4) What is...
When a large amount of water was poured on 100. g of calcium carbide, 28.3g of acetylene was produced. Calculate the percent yield of acetylene in the reaction.
Acetylene may be produced from the reaction between calcium carbide and water. How many moles of acetylene are present in a 500.0 mL sample of gas collected over water at 20.0°C and a total pressure of 758 torr? The vapor pressure of water at 20.0 °C is 17.54 mm Hg. 0.0202 moles acetylene 0.0207 moles acetylene 0.297 moles acetylene 0.304 moles acetylene
Calcium carbide (CaC) is manufactured by the reaction of CaO with carbon at a high temperature (calcium carbide is then used to make acetylene): CaO (s)+3C (s) + CaC2 (s)+CO (g) AH =+464.8 kJ mol- Is this reaction endothermic or exothermic? If 10.0 g of CaO is allowed to react with an excess of carbon, how much heat is absorbed or evolved by the reaction?
