Daltons atomic theory was accepted because

A sample of gas is held at constant pressure. Increasing the Kelvin temperature of this gas sample causes the average kinetic energy of its molecules to (1) decrease and the volume of the gas sample to decrease (2) decrease and the volume of the gas

When N2 (g) reacts with H2 (g) to form NH3 (g), 92.2 kJ of energy are evolved for each mole of N2 (g) that reacts. Write a balanced thermochemical equation for the reaction with an energy term in kJ as part of the equation.
