Answer:
The empirical formula for propane is C3H8.
Answer:
I think option A is correct answer
Explanation:
option A
To solve this we need to have knowledge of differential rate law which relate the rate to the concentration and time. Therefore, the rate of overall reaction is 1x10⁻²M/s.
<h3>
What is differential rate law? </h3>
A differential rate law represents the rate of a reaction . According to this rate is directly proportional to changes in the concentration of reactants and inversely proportional to specific interval of time. There is another expression of rate law which is integrated rate law which is just opposite of differential rate law.
The given equation is
2NO + O 2NO
(1/2) Rate of disappearance of NO= rate of disappearance of C= (1/2)rate of appearance of NO= rate of overall reaction.
(1/2)rate of appearance of NO= rate of overall reaction.
rate of appearance of NO=2x10⁻²M/s.
Substituting the values in above equation
(1/2)×2x10⁻²M/s = rate of overall reaction.
rate of overall reaction= 1x10⁻²M/s
Therefore, the rate of overall reaction is 1x10⁻²M/s.

Answer:
The answer to your question is: Cp = 350.4 J/ kg°C
Explanation:
Data
mass = m = 4.7 g convert grams to kilograms 0.0047 kg
heat= Q = 52.7 J
Temperature = 25 - 57 °C
Formula
Q = mCpΔT solve for Cp
Cp = Q / mΔT
Process
Cp = 52.7 / [(0.0047)(57 - 25)] Substitution
Cp = 52.7 / 0.1504
Cp = 350.4 J/ kg°C
The answer to this question is C. Freezing, hope this helps :)
