Answer:
Q.1When a soda bottle is opened, the solubility of CO2 in the water decreases due to decrease in pressure in the bottle once it is opened. Thus the gas escapes out. Therefore it is not a physical change.
Q.2 An oxidizing agent may either add oxygen to a substance or remove hydrogen from it. It involves loss of electrons.
