Answer:
The new volume of a gas at 750 mmhg and with a volume of 2. 00 l when allowed to change its volume at constant temperature until the pressure is 600 mmhg is 2.5 Liters.
Explanation:
Boyle's law states that the pressure of a given amount of gas is inversely proportional to it's volume at constant temperature. It is written as;
P ∝ V
P V = K
P1 V1 = P2 V2
Parameters :
P1 = Initial pressure of the gas = 750 mmHg
V1 = Initial pressure of the gas = 2. 00 Liters
P2 = Final pressure of the gas = 600 mmHg
V2 = Fimal volume of the gas = ? Liters
Calculations :
V2 = P1 V1 ÷ P2
V2= 750 × 2. 00 ÷ 600
V2 = 1500 ÷ 600
V2 = 2.5 Liters.
Therefore, the new volume of the gas is 2. 5 Liters.
I'm not 100% sure but I think it's false
Answer: -Ionic solids are brittle and hard because the electrostatic attractions in the solid again hold the ions in definite positions. Explanation; -Ionic solids are rigid because the multiple interactions between oppositely charged ions hold the charged particles in relatively fixed positions.

Siri answered that question but hope it helps
a gas exert a pressure of 6.20 atm in a container with a volume of 475.2 ml will exert a pressure of 9.150 atm when transferred to a container with a volume of 322 ml
Explanation
This is calculated using the Boyles law formula
that is P1V1= P2V2
P1=6.20 atm
V1=?
P2=9.150 atm
V2= 322 ml
by making V1 the subject of the formula
V1= P2V2/P1
V2 is therefore = (9.150 atm x322 ml) / (6.20 atm-) = 475.2 ml
