Boyle's law gives the relationship between pressure of a gas and volume of gas.
It states that at constant temperature, pressure of gas is inversely proportional to volume of gas.PV = k
where P - pressure V- volume and k - constant
P1V1 = P2V2
since the gas occupies the volume of the container, volume of gas is taken as volume of container.
100kPa x 5.0 L = 50 kPa x V
V = 10.0 L

Answer: The enthalpy change for this reaction is 392 Joules
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
where,
n = number of moles
Now put all the given values in this expression, we get
Therefore, the enthalpy change for this reaction is 392 Joules
Answer:
The answer t your question is below:
Explanation:
When a salt is mixed with water, it will form ions, these ions are soluble in water.
Example: Ca(NO3)2 ⇒ Ca⁺² + 2 NO₃⁻¹
Both Ca⁺² and NO₃⁻¹ are soluble in water.
Then the answer to your question is:
<u>Soluble because all Ca+2 compounds are soluble in water
</u>
S<u>oluble because all NO3−1 compounds are soluble in water
</u>
