Answer:
3.91 × 10⁴ J/mol
Explanation:
We can calculate the heat of solution using the following expression.
Q = c × m × ΔT
where,
c is the specific heat capacity of the solution
m is the mass of the solution
ΔT is the change in the temperature
The mass of LiCl is:
The mass of the solution is:
m = mLiCl + mH₂O = 10.6 g + 200.0 g = 210.6 g
Q = c × m × ΔT = (4.184 J g⁻¹ °C⁻¹) × 210.6 g × 11.08 °C = 9763 J
In a constant pressure calorimeter, the molar enthalpy of solution for LiCl is:
Answer:
The answer is "As 
, at high-temperature 
and When
."
Explanation:
The equation for the reaction is:
At equilibrium,
When k=5.8(>1), the value of 
would be positive
So, 
is negative (< 0)
So if K > l, 
If the reaction is not in equilibrium so the equation is :
=
Substituting the expression:
It is the positive value for all temperatures.
So, As Q = 336, at the high temperature .
Astronauts brought back 500 lb of rock samples from the moon. How many kilograms did they bring back? (1 kg = 2.20 lb)
A. 500 kg
B. 1,100 kg
C. 498 kg
D. 227 kg
I believe it is D.
It should have 10 electrons
