Complete the chemical combustion reaction of naphthalene, which demonstrates the conservation of mass.
C10H8 + 1202 >>

Explanation:

Hello,

In this case, since combustion reactions yield carbon dioxide and water via the following equation:

In such a way, for naphthalene, its combustion reaction is:

Whereas we see ten carbon atoms, eight hydrogen atoms and twenty four oxygen atoms at both reactants and products as a proof of the law conservation of mass.

Regards.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

12 is it do you think so
