Answer:
Option-B (2-methylpropene)
Explanation:
The reaction scheme is attached below,
In first step the alkene acts a nucleophile and adds H⁺ across double bond yielding a stable tertiary carbocation.
In the second step the oxygen atom of methanol acts as nucleophile and attacks the positive charge carrying carbon atom resulting in the formation of t-butyl methyl ether.
Boyle's Law
Pressure 1 × Volume 1 = Pressure 2 × Volume2
or P1×V1= P2×V2
Finding Volume 2
(5.75atm)(5.14L) = (2.49atm)(V2)
Then Multiply
29.55atm•L = 2.49atm(V2)
Divided by 2.49
29.56atm•L / 2.49atm = 2.49atm(V2) / 2.49atm
V2= 11.87 L
Answer:
46148 J
Explanation:
You need to calculate the heat associated with each of the following steps. You will need to know some specific heats (they are probably given to you somewhere).
Step #1: Condensation
Step #2: Cooling from 100 C to 0 C
Step #3: Freezing
Step #4: Cooling from 0 C to -32 C
Step #1:
q = mC
q = 15 g (-2256 J/g )
q = -33840 J
Step #2:
q = mcΔT
q = 15 g (4.19 J/g/C)(-100 C)
q = 6285
Step #3:
q = mC
q = 15 g (-334 J/g)
q = -5010
Step #4:
q = mcΔT
q = 15 g (2.11 J/g/C)(-32 C)
q = -1013
Keep in mind the - signs indicate heat is being released. To calculate the total heat released, add the individual heats calcualted at each step:
Total heat released = 33840 + 6285 + 5010 + 1013 = 46148 J
Some chemical properties of nitrogen are...Nitric acid salts, potassium nitrate, trinitrotoluene, ammonium nitrate, and nitro-glycerine.
