because that would take long... i did because u guyz can see this...
how come there is no C in first blank because it is metane
the formula for methanoic acid is HCOOH
meth ---> 1
when you use "meth" you should have 1 Carbon atom in the chain
and there is already 1 carbon atom in the COOH
if you have 2 carbon atoms in the chain, it will be ethanoic acid then ---the formula will be CH3COOH
the blank before HCOOH is for balancing the equation
Please make it sure with someone

How come i am again out of questions?
