Question 1 (1 point) If PV = nRT, then if I increase the amount of moles of a gas in a glass jar,
and the temperature of the gas stays the same,
and volume of a jar obviously stays the same,
what will happen to pressure inside the jar?

The pressure also increases.

Explanation:

As we can see in this equation,

Pressure is directly proportional to the moles of a gas in the glass jar.

Temperature and Volume remains constant.

Hence, if number of moles of a gas increases, the pressure also increase "n" number of times.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
