1. A mixture of two oxides (barium oxide and calcium oxide -4.88 g total) was reacted with a quantity of carbon dioxide gas at 35 °C and 746 mmHg in a 1.46 Liter flask. At the reaction's end, the pressure in the flask fell to 252 mmHg. Calculate the percent composition of the mixture. Note: The combination of a metal oxide with carbon dioxide gas will form a carbonate salt as the only product. Lithium hydride (LiH) reacts with water...
