Acetylene is a very weak acid; however, it will react with moist silver(I) oxide and form water and a compound composed of silver and carbon. Addition of a solution of HCl to a 0.2352-g sample of the compound of silver and carbon produced acetylene and 0.2822 g of AgCl. (a) What is the empirical formula of the compound of silver and carbon? (b) The production of acetylene on addition of HCl to the compound of silver and carbon suggests that the carbon is present as the acetylide ion, C 2 2- . Write the formula of the compound showing the acetyl ide ion.

"Water gas" is an industrial fuel composed of a mixture of carbon monoxide and hydrogen gases. When this
fuel is burned, carbon dioxide and water result. From the information given below, write a balanced equation
and determine the enthalpy of this reaction:
CO(g) + O2(g) → CO₂(g) + 282.8 kJ
H2(g) + O2(g) → H₂O(g) + 241.8 kJ
