Question 26 SHOW WORK Given the following reaction: CaC 2(s) + 2H 20 -C2H 2(g) + Ca(OH) 2(aq) Assume that you place 1.85 g of calcium carbide in excess water and collect the acetylene gas over water. Calculate the maximum amount of gas that should be produced in grams round answer to 3 decimal places omit trailing zeroes The actual volume of acetylene and water vapor collected is 810 ml at 30.5°C with a pressure of 557.524 mmHg. Calculate the actual amount of gas collected(in grams) round answer to 3 decimal places omit trailing zeroes The vapor pressure of water at 30.5°C is 32.35 mmHg. Calculate the percent yield of acetylene. round answer to 2 decimal places omit trailing zeros A Moving to another question will save this response.
Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
