Solution :
<u>Explanation 1 </u>:
Spontaneity of the reaction is based on two factors :
-- the tendency to acquire a state of minimum energy
-- the energy of a system to acquire a maximum randomness.
Now, since there isn't much difference in the bond enthalpies of B-F and B-Cl. So, we can say the major driving factor is tendency to acquire a state of maximum randomness.
<u>Explanation 2 </u>:
A system containing the B halides has a than a system of and .
It has the same number of , but more distinguishable kinds of , hence, more microstates and higher entropy.
Answer:
The answer to your question is Volume = 600 ml
Explanation:
Data
Volume 1 = 810 ml
Temperature 1 = 270°K
Pressure 1 = 1 atm
Volume 2 = ?
Pressure = 2 atm
Temperature 2 = 400°K
Process
1.- To solve this problem, use the Combine gas law.
P1V1 / T1 = P2V2 / T2
- Solve for V2
V2 = P1V1T2 / T1P2
2.- Substitution
V2 = (1)(810)(400) / (270)(2)
3.- Simplification
V2 = 324000 / 540
4.- Result
V2 = 600 ml
Explanation:
mole of acid/mole of base=(concentration of acid×volume of acid)/(concentration of base×volume of base)
Na/Nb=CaVa/CbVb
1/2=(Ca×16.7)/(0.2×25)
0.2×25=2×Ca×16.7
Ca=(0.2×25)/(2×16.7)
Ca=0.15mol/dm³
mole of acid=Concentration×volume
mole of acid=0.15×(16.7/1000)
mole of acid=2.5×10^-3moles
Answer: Combustion
Explanation:
Methane gas or natural gas is the hydrocarbon that reacts with oxygen as shown below: CH4 + 2O2 → CO2 + 2H2O There are two types of combustion reactions: complete and incomplete combustion. Therefore there are four products, carbon dioxide, water, carbon, and carbon monoxide.
