Explanation:

According to the Reaction,  1 mole of x reacts with 1 mole of y and 1 mole of z. 

⇒ Also, 1 atom of x reacts with 1 atoms of y and 1 molecules of the z. 

(a). 1 atom of x reacts with 1 atom of y and 1 molecules of z. 

∴ 200 atoms of x reacts with 200 atoms of y and 200 molecules of x. 

In this, Molecules of the z required is greater than the molecules of the z present. Hence, z is the limiting reactant and x and y is in the excess. 

(b). 1 mole of the x reacts with 1 mole of y and 1 mol of z.

In this, number of the moles of the y are present in the high amount as required by the Reaction, hence it is the Excess reagent. 

∴ x and y is the limiting reagent in the reaction. 

(c). 1 atoms of x reacts with the 1 atoms of y and 1 molecules of the z. 

∴ 50 atoms of the x reacts with the 50 atoms of the y and 50 molecules of the z. 

In this, numbers of the atoms of y required is greater than what is present.

∴ y is the limiting reagent.

(d). 1 mol of the x reacts with 1 mol of y and 1 mole of the z.

∴ 5 mol of x reacts with the 5 mol of y and 5 mol of the z. 

In this, numbers of the moles of the x required is greater than what is present, therefore x is the limiting reactant or reagent. 

Hope it helps.
