When 0.5 moles of Zn react with 0.4 moles of HCL the limiting reactant will be HCL and excess reactant is Zn 0.3 moles excess and 0.2 moles Zn will be consumed in the reaction.

<h3>What is the limiting reactant in the given equation ?</h3>

STEP1- Write the balanced equation

            Zn +   2HCL   →  ZnCl₂  + H₂

STEP2- calculate the moles according to the reaction

             1mol of Zn requires  →  2moles of HCL

              0.5 moles of Zn requires→ 1mol of HCL

              Given moles of HCL is 0.4

STEP3- Apply unitary method

            0.5/x=1/0.4

             0.5×0.4= x

              0.2=x

STEP4- excess reagent left 0.5-0.2=0.3

Hence, the 0.3mole of excess Zn is left

Answer 1) Cl_{2} + H_{2} ----> 2 HCl 
This is a pure chemical reaction that is taking place.

In this reaction the two chemical species which are Chlorine and Hydrogen undergo addition reaction and form two moles of hydrochloric acid. No new species is formed except the combination of reactants which gives the product.

Answer 2) H + H ----> He + n
This is a nuclear reaction.

As the reactant species is undergoing a reaction which is resulting in formation of new species completely different than the elements in reactants. 

Also there is a neutron which is generated after the reaction this is clear indication of nuclear fusion reaction. Hence, it can be called as nuclear reaction.
