I think u turn down the heat not to sure
Answer:
Explanation:
It is possible to answer this question knowing Hess's law that says you can sum half-reactions enthalpy cahnge to obtain enthalpy change of the total reaction. Using the reactions:
<em>(1) </em>2NO(g) → N₂(g)+O₂(g) ΔH = -180,6 kJ
<em>(2) </em>N₂(g) + O₂(g) + Cl₂(g) → 2NOCl(g) ΔH = +103,4 kJ
The reverse reactions of (1) and (2) are:
<u>N₂(g)+O₂(g)</u> → 2NO(g) ΔH = +180,6 kJ
2NOCl(g) → <u>N₂(g) + O₂(g)</u> + Cl₂(g) ΔH = -103,4 kJ
The sum of these reactions is:
2NOCl(g) → 2NO(g) + Cl₂(g) ΔH = +180,6 kJ -103,4 kJ = <em>77,2 kJ</em>

properties calculations are used for this type of problem. Calculations are as
follows:<span>
</span>Look up the freezing point of benzene, then delta T = f.p.=3.5 = Kf*m
<span>Solve for molality. </span>
<span>molality = moles/kg solvent </span>
<span>Solve for moles. </span>
<span>moles acetic acid = grams acetic acid/molar mass acetic acid </span>
<span>Solve for molar mass. You would expect to find 60 for the molar mass CH3COOH.</span>
