At STP, 37 L of acetylene (C2H2) reacts with excess oxygen (O2). What is the volume...
2) Oxyacetylene torches are fueled by the combustion of acetylene, C2H2 2 C2H2 + 5 O2 (g) 4 CO2 (g) + 2 H2O (g) If the enthalpy change for the reaction is -251 1.14 kJ/mol, a) How much heat can be produced by the reaction of 10 g of C2H2? b) Is it an endotherm ic or exothermic reaction? Molar mass of acetylene is 26.04 g/mol.
When a mixture of 13.0 g of acetylene (C2H2) and 13.0 g of oxygen (O2) is ignited, the resultant combustion reaction produces CO2 and H20. The unbalanced equation for this reaction is shown below: C2H2 + O2 +CO2 + H2O Part C How many grams of C2H, are present after the reaction is complete? VALO ? m = Бn Submit Request Answer

Write a balanced equation for the chemical reaction Acetylene gas (C2H2) burns in a welding torch with oxygen to form carbon dioxide gas and water vapor.C2H2(g) + O2(g) ==> CO2(g) + H2O(g) It isn't balanced. I will leave that for you.How do I balance it?trial and error. C2H2 + O2 ==> CO2 + H2O. I see 2 C on the left and only 1 on the right so I place a coefficient of 2 for CO2 on the right. And...
1. Acetylene (C2H2) undergoes combustion in excess oxygen to generate gaseous carbon dioxide and water. Given AH [CO2(g)] = -393.5 kJ/mol, AH [H20(8)] = -241.8 kJ/mol, and AH[C2H2(g) = 226.6 kJ/mol, how much energy is released (kJ) when 92.5L of CO2 gas are produced at 225atm and 785°C?
Calculate the standard enthalpy of formation of gaseous acetylene (C2H2) using the following thermochemical information: 2 C2H2(g) + 5 O2(g) 4 CO2(g) + 2 H2O(l) H = -2599.3 kJ CO2(g) C(s) + O2(g) H = +393.5 kJ 2 H2O(l) 2 H2(g) + O2(g) H = +571.7 kJ H = kJ
