No, a gas formed by the reaction of n2 with o2 in internal combustion engines

Describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? )

The activation energy for the reaction no2(g)+co2(g)⟶no(g)+co(g) is ea = 300 kj/mol and the change in enthalpy for the reaction is δh = -100 kj/mol . what is the activation energy for the reverse reaction?

What happens in the particles of a gas when the gas is compressed
