The answer is Na < Cl
Chlorine is more electronegative than sodium because this follows the trend of the periodic table. The trend states that an element's electronegativity increases from left to right of a period and bottom to up of a group. Since sodium and chlorine are from the same period, and chlorine is at the right of sodium, chlorine is more electronegative.
The formation of hydrogen cyanide, HCN is formed by reacting hydrogen gas, carbon and nitrogen gas, expressed in the following expression below:
<span>½ H2 (g) + C (s) + ½ N2 (g) → HCN (g) ΔHof = 135 kJ
</span>
At standard conditions, hydrogen and nitrogen exist as gases while carbon is solid. This is also an endothermic reaction due to the positive <span>ΔHof</span>

Explanation:
An object at rest has no acceleration. An object wishes to maintain its current acceleration. Basically all objects wish to not experience inertia. They want to keep the acceleration they're currently at.
