Melting point is dependent on the intermolecular forces which means the bonds between the molecules of bromine as it is a simple molecular structure
Heat energy. The heat allows air to expand allowing more space for molecules to move around.
Answer: The freezing point of 3.46 gram of a compound X in 160 gram of benzene is 
Explanation:
The relation of density and molar mass is:
where
d = density = 3.27 g/ L
P = pressure of the gas = 773 torr = 1.02 atm (760 torr = 1atm)
M = molar mass of the gas = ?
T = temperature of the gas = 
R = gas constant = 
The relation of depression in freezing point with molality:
= depression in freezing point = 
= 
= freezing point constant = 5.1
m = molality = 
Thus the freezing point of 3.46 gram of a compound X in 160 gram of benzene is
Answer:
A Bunsen bumper,named after Robert Bunsen, is a kind of gas burner used as laboratory equipment;it produces a single open gas flame ,and used for heating ,sterilization,and combustion. The gas can be natural gas (which is mainly methane) or a liquefied petroleum gas,such as propane,butane,or a mixture
Explanation:
B. A mixture of flour, sugar, eggs, and butter is baked to become a cake. Remember chemical change is when a substance combines with another to form a new substance. The answer wouldn't be A because the flour and sugar are mixing together, but they could be separated to their original forms. It wouldn't be C because the egg is only broken not chemically changed or formed with anything else. It wouldn't be D because the chocolate squares could be frozen or hardened to change it from icing. B is the best answer. Hope this helps!
