The gas will expand as it is heated.
The gas expands.
the mass of the balloon increases because the size of the balloon has increased. :)
Because the gas inside expands with the heat
it becomes low

The molecules of a gas move faster when heated so the pressure increases.

A chemical reaction in a hot air balloon can be when the propane is heated up. That is a chemical reaction because something has heated up.

No. A hot air balloon is a solid object. That is, the basket, the ropes, the burner and the envelope itself are not gasses. The air within the envelope is a gas, of course; heated atmospheric gasses in fact. But the balloon itself is not a gas.
