Hey there!
Compounds with ionic bonds have higher melting points because of the forces needed to break through the strong forces of attraction holding it together.
Compounds with covalent bonds have lower melting points because less energy is needed to break the weaker forces of attraction.
So, your answer is C. Compound 1 is ionic, and compound 2 is molecular.
Hope this helps!
The correct Answer Is : D
Answer:
V2 gas = 2.33 L
Explanation:
assuming ideal gas:
∴ n gas = 1 mol
∴ P1 standard = 1 atm
∴ V1 gas = 3.5 L
∴ P2 = 1.5 atm ⇒ V2 = ?
state 1:
∴ P1V1 = nRT1
⇒ P1V1/T1 = nR
state 2:
⇒ P2V2/T2 = nR
(1) = (2)
⇒ P1V1/T1 = P2V2/T2
assiming: T1 = T2
⇒ P1V1 = P2V2
⇒ V2 = P1V1/P2
⇒ V2 = ((1 atm)(3.5 L))/(1.5 atm)
⇒ V2 = 2.33 L
It true I jus answered it and got it right
