Answer: Boyle's Law
Explanation:
Boyle's Law which is also called Mariotte's law was formulated by physicist Robert Boyle in 1662.
It posits that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature.
As the Scuba Diver went deeper, the volume of air dropped so the pressure increased.

The atoms undergo chemical changes.
New substances may be a product of the reaction.
Answer:
All substances that are made up of the same kind of mole ules are called pure substances.
So what do you mean ?
Explanation:
Answer:
⇒ We have Na2O + H2O --> NaOH. We have 2 sodiums and 2 oxygens and 2 hydrogens on the left side, but only one of each on the right side.
Sodium Oxide + Water → Sodium Hydroxide
⇒ Na2O + H2O → 2NaOH .
Sodium oxide is used in ceramics and glasses. Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution.
The correct option is B. To increase the production of ammonia, you have to increase the pressure of the system. Increase in pressure will result in increased production of ammonia because this will drive the chemical reaction forward.
