I think that it is D because the higher the molecular mass, the higher it's boiling point. I hope that helped:) Bye!
Solution. because the substances can't go back to their original form. like kool aid, when its mixed you cant separate the powder and the water again.
That is FALSE because neutrons have no charge and as their name suggest are neutral particles.
Answer:
B
101L
Explanation:
We use the ideal gas relation
PV = nRT
P = pressure = 101.3KPa
V = volume = ?
n = number of moles = 4.5moles
T = Temperature = 273.15K
R = molar gas constant = 8.314J/mol.k
Rearranging the equation to make V the subject of the formula yields :
V = nRT/P
= ( 4.5 × 8.314 × 273.15) ÷ 101.3
= 10,219.361 ÷ 101.3 = 100.88L which is apprx 101L
