Equation with state symbols
WebQuestion: 1. Write a balanced chemical equation, including physical state symbols, for the combustion of liquid nonane into gaseous carbon dioxide and gaseous water. 2. Suppose 0.160 kg of nonane are burned in air at a pressure of exactly 1 atm and a temperature of 16.0 °C. Calculate the volume of carbon dioxide gas that is produced. WebThings to notice about the equation. The state symbols - (g) - are essential. When you are talking about ionisation energies, everything must be present in the gas state. Ionisation energies are measured in kJ mol-1 (kilojoules per mole). They vary in size from 381 (which you would consider very low) up to 2370 (which is very high).
