Answer:
The answer to your question is Energy = 36.036 J
Explanation:
Data
mass of Copper = 39 g
ΔT = 24°C
C = 0.0385 J/g°C
Q = ?
To calculate the energy absorbed just substitute the values given in the specific heat formula.
Q = mCΔT
Substitution
Q = (39)(0.0385)(24)
Simplification
Q = 36.036 J
This is an incomplete question, here is a complete question.
Consider the second-order decomposition of nitroysl chloride:
At 450 K the rate constant is 15.4 atm⁻¹s⁻¹. How much time (in s) is needed for NOCl originally at a partial pressure of 53 torr to decay to 10.6 torr?
Answer : The time needed for NOCl is, 2.52 seconds.
Explanation : Given,
Rate constant =
Initial partial pressure of NOCl = 56 torr = 0.0737 atm
final partial pressure of NOCl = 14.5 torr = 0.0191 atm
The expression used for second order kinetics is:
where,
k = rate constant
t = time
= concentration at time 't'
= initial concentration
As we know that,
Thus, the expression of second order kinetics will be:
As,
So, ............(1)
Now put all the given values in the above expression 1, we get:
Therefore, the time needed for NOCl is, 2.52 seconds.
Answer:
The molecular formula of mono sodium glutamate is
Explanation:

let the molecular formula be
Percentage of carbon in the M.S.G. =35.52 %
a = 5
Percentage of Hydrogen in the M.S.G. = 4.77 %
b = 8
Percentage of oxygen in the M.S.G. =37.85 %
c = 3.99 ≈ 4
Percentage of nitrogen in the M.S.G. = 8.29 %
d = 1
Percentage of sodium in the M.S.G. =13.60 %
e = 0.99 ≈ 1
The molecular formula be :
