Answer:
Determining flammability can be as simple as holding a sample of the substance over a match. If it burns, it is flammable, leading to additional experiments to find more properties. Measuring the heat given off by the substance when it burns gives the heat of combustion.

A compound or a mixture.
If it is two or more elements are mixed, it is a mixture. If two or more elements are chemically reacted, it is a compound ( example FeS)

A. There is very little empty space in a gas in not part of the kinetic molecular theory of gases.
Explanation:
The kinetic molecular theory of gases follows following points:
Kinetic energy does not change or get dissipated when gas molecules collide with each other. No attraction or repulsion between gas particles is observed. Particles of gas are moving randomly in all directions. Temperature increase cause the rapid movement of gas particles.The gas particles are placed very far from each other as compared to liquid.
The empty space in a gas is large because gas gets compressed in the small volume of the container also.
