Sorry it’s upside down but i really need with these 2 can someone explain

Explanation:

26)

n = 13.23 mol

Explanation:

Volume = 72 L

Pressure = 344.4 KPa (344.4/101 = 3.4 atm)

Temperature = 225 K

Moles of gas = ?

Solution:

PV = nRT

n = PV/RT

n = 3.4 atm . 72 L / 0.0821 atm. L /mol. K . 225 K

n = 244.8 mol /18.5

n = 13.23 mol

c) The balloon might pop due to increase in volume of gas by the heat.

Explanation:

It is known that every thing expend on heating. when balloon is inflated to its capacity in summer it will pop because gas inside it get warmer because of heat and gas molecules move faster because of high kinetic energy. Thus gas expand and put force on balloon which then get explode.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."
