When CO(g) reacts with H₂O(1) to form CO₂(g) and H₂(g), 0.669 kcal of energy are absorbed for each mole of CO(g) that reacts. Write a balanced equation for the reaction with an energy term in kcal as part of the equation. Use the SMALLEST INTEGER coefficients possible and put the energy term in an appropriate box.

25. An indlcation of the average formula weight of a fat is its saponification number, expressed asthe mlligrams KOH requlred to hydrolyze (saponify) 1 g of the fat: CH,CO,R CH,OH CHCO,R + 3KOH → CHOH + 3RCO,K CH;CO,R CH,OH where R can be variable. A 1.10-g sample of butter is treated with 25.0 mL of 0.250 M KOH solution. After the saponification is complete, the unreacted KOH is back-titrated with O.250 M HCI, requiring 9.26 mL. What is the saponification number of the fat and what is its average formula weight (assuming the butter is all fat)?
