Answer:
by pumping blood throughout the body.
Explanation:
There are O-H bonds in H2O. They have the intramolecular force of polar covalent bond.
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>
