Answer:
T= 257.36 k
Explanation:
using the ideal gas law
pv=nRt
first, convert pressure from mmhg to kpa
312 x (101.3\760)= 41.58 kpa
R is constant= 8.31
to get n(number of moles)
n=m\M (m is mass, M is molar mass)
molar mass of argon is 39.948
n= 2.33\39.948
n=0.0583
substitute;
41.58 x 3 = 0.0583 x 8.31 x T
T= (41.58 x 3)\ (0.0583 x 8.31)
T= 257.36 k

Answer:
Molecular- compound B, Ionic - compound A
Explanation:
Molecular compounds are compounds containing two or more non-metal for example carbon dioxide and covalent in nature. They usually have low melting and boiling points and will vaporized faster. Compound A on the other hand is ionic; they usually have high melting and boiling points and when dissolved in water they dissociate into ions ( actions and anions)
