- Feb 24, 2020 · Enthalpy is the thermodynamic function that describes heat flow. The calculation of the heat that is gained or lost can be determined by using the formula q = nCΔT. A negative result indicates that heat is lost when the reaction takes place, and a positive result indicates that heat is gained.

Jan 13, 2012 · 2C2H2 + 5O2 → 4CO2 + 2H2O. Gas problems are very easy - when you have a balanced equation, call everything litres: 2litres of C2H2 react with 5 litres O2 to produce 4 litres CO2 and 2 litres H2O vapour. The question deals with 75L of CO2. multiply throughout by 75/4 = 18.75 Question 3 3 pts For the reaction 2C2H2() + 5O2(g) → 4CO2(g) + 2H2O(1) 3.0 L of C2H2 reacts with 4.0 L of O2. What is the total volume, in L, of all gases present after the reaction goes to completion? 4.6 L 7.0L 3.1 L 4.0L U Question 4 3 pts A sample of gas has an initial volume of 5.6 L at a pressure of 2.0 atm.
