Answer:
The correct answer is D) The volume of the gas will increase.
Explanation:
According to Charles's Law, at constant pressure, as the temperature (T) of a gas increases, the volume (V) increases and vice versa. This is observed according to the formula:
V1 / T1 = V2 / T2
Lidocaine is used as a local anesthetic and cardiac depressant. when lidocaine reacts with HCL, the tertiary amine reacts with HCL to form an amine salt of lidocaine hydrochloride. This reaction reaction can be represented as
Nitric acid is a corrosive acid and leaves the human skin stained yellow due to its reaction with keratin.
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
