CHCH4 change to compounds CH4
<span>When you have to balance an equation it means that you have to balance both parts of equation so that the numbers of each elements will have the same amount. According to this rule, it is quite easy to distinguish unbalanced reaction, and the answer is a) HBr + Ca(OH)2 → CaBr2 + H2O as you can see that amount of oxygen on both sides is not the same.</span>
Answer:Cl2
Explanation:
Diatomic gases always possess dispersion forces as their strongest intermolecular force. Dispersion forces are the primary intermolecular interaction existing between gases containing homonuclear covalent bonds. The other substances mentioned either possess a permanent dipole, or are purely ionic in nature. Hence the answer!
