What is the product of (structural formula):
methyl acrylate ch2=chcooch3 with hcl
methyl acrylate with h2/pt

Structural formula of reactions is in the picture

Explanation:

The reaction of a alkene with HCl is called "alkene hydrohalogenation". The alkene "attacks" hydrogen. The hydrogen occurs following Markovnikov rule:

" Hydrogen takes place at the less substituted carbon atom of the double bond".

Then, Cl⁻ attacks the other position of the initial double bond giving as result the blue structure,

The second reaction is the alkene hydrogenation that gives as result the respective alkane (Red structure).

I hope it helps!
