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:
D
Explanation:
We can use the mole ratio to calculate the partial pressure. The total number of moles is 0.2 + 0.2 + 0.1 = 0.5 moles
Now, we know that the mole fraction of the argon gas would be 0.2/0.5
The partial pressure is as follows. To calculate this, we simple multiply the number of moles by the total pressure.
0.2/0.5 * 5 = 1.0/0.5 = 2.00atm
D
Answer:
no.
Explanation:
only one planet would be made gas
is earth. and for what you mean like when
planet would be made of gas my answer is no
because theirs so gravity but im not the one
who's deciding and god is the one who's deciding
if when is the other planet having a gas
i know im wrong
Answer:
i think protons and neutrons
Explanation:
im not sure tho
