number 2 because the curve demstrates the crest GOOD LUCK i hope i got you the correct answer if not sorry
Answer:
0.0619 m^3
Explanation
number of moles = n = 4.39 mol
pressure = P = 2.25 atm =2.25×1.01×10^5 Pa= 2.27×10^5 Pa
Molar gas constant =R = 8.31 J/(mol K)
Temperature T= 385K
volume of gas = V =?
BY GENERAL GAS LAW WE HAVE
PV = nRT
or V = nRT/P
or V = (4.39×8.31×385)/(2.27×10^5)
V = 0.0618728
V = 0.0619 m^3
It is incorrect, because the identity of the original product has changed. Ca3(OH)2 does not exist! It is no longer calcium hydroxide. To balance an equation, you must manipulate the coefficients, a.k.a. the big numbers that go before reactants or products. Subscripts, the little numbers inside the reactants or products, cannot be changed without completely changing the substance.
Answer:
-3.63 degree Celsius
Explanation:
We are given that
Boiling point of solution=
C
Boiling point water=100 degree Celsius
Where 
=Boiling point of solution
Boiling point of pure solvent
C
Using the formula
Molality,
m
Using the formula
We know that
Where 
=Freezing point of solvent
Freezing point of solution
Using the formula
Freezing point of water=0 degree Celsius
Hence, the freezing point of solution=-3.63 degree Celsius
