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!

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
