The correct answer is (a.) decomposition. The equation NaCl --> Na + Cl is a decomposition reaction. That is because the synthesis reaction looks like this Na + Cl = NaCl, and is the opposite of the decomposition. The decomposition reaction is the chemical reaction in which a single compound break into new compounds.
According to Boyle's Law, volume is inversely proportional to pressure. It means
if the volume of a gas goes up the pressure goes down and if the volume of the gas goes up the pressure goes down. When the pressure of air inside the inflated balloon is more than the atmospheric pressure outside the balloon. And also when the density inside is greater than the density outside. The molecules inside the balloon move and bang around the inner walls which produces force, which provides the pressure of an enclosed air.
