Why do some compounds form double or triple bonds?
2 answers:
Answer:
Some compounds form double or triple bonds so they can become more stable.
Explanation:
A Lewis structure for CO₂ that obeys the octet rule and has only single bonds would be the first formula below.
The molecule can become more stable if the single electrons move into the regions between the nuclei to form double bonds as in the second formula below.
The electrons can then hold the nuclei more tightly together and make the molecule more stable.

Answer: molecules of water are produced.
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
2 moles of produce = 3 moles of
Thus 0.707 moles of will produce=
of
According to avogadro's law, 1 mole of every substance contains avogadro's number of particles.
Thus 1.06 moles of contains =
