Write a balanced chemical equation that shows the formation of 3-methylbutanoic acid from the elements carbon (C), hydrogen (H2 ) and oxygen (O2 ).

Explanation:

Hello there!

In this case, according to the given information, and considering that the molecular formula of 3-methylbutanoic acid is:

Thus, the formation reaction is:

However, it must be balanced because of the unequal number of carbon and hydrogen atoms yet those of oxygen seem to be balanced:

Regards!

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
