The given chemical reaction is:
The standard heats of formation of are:
Δ) = -285.8kJ/mol[/tex]
Δ) = -187.6 kJ/mol[/tex]
Calculating the change in heat:
Δ=∑ΔH
-∑ΔH
= [{2 * (-285.8 kJ/mol)} -{2*(-187.6 kJ/mol)}]
= -196.4 kJ/mol
Therefore, the change in enthalpy for the given reaction is -196.4 kJ/mol
Answer:
Explanation:
I want to believe that your question is how to find an 8M carbon chloride solution using the given mass of the compound.
The problem clearly identifies with concentration of a substance. Molarity is one of the ways of expressing concentration. It is the amount of solute of a substance per volume of solution.
Molarity =
To find the right mix that will give us 8M carbon chloride solution, let's explore how to figure out the appropriate volume.
Clearly given is the mass of the compound, convert to number of moles.
Number of moles =
Molar mass of carbon chloride(CCl₄) = 12 + 4(35.5) = 154g/mol
Number of moles = = 0.57moles
To find the volume;
8 =
volume = 0.071L or 71mL
