Calculating Limiting Reactant & Theoretical Yield of NaCl2

[amrisha16]

if there is 53.2g of Na and 65.8g of Cl, what is the limiting reactant and Theoretical Yield of NaCl2?

what is the maximum amount of Ammoniac that can be synthesized from 25.2g of Nitrogen and 8.42g of Hydrogen?

need help in that... please...

The specie of NaCl₂ for your first reaction is unlikely.

In both reactions which you ask, the MOLE ratios of each reactant is necessary for you to find the limiting reactant. You find the number of moles using the atomic weight of the reacting element.

For "ammoniac", did you mean "ammonia"? How many moles Nitrogen in 25.2 grams? How many moles of Hydrogen in 8.42 grams of Hydrogen? What ratio of one to the other is necessary for a mole of ammonia?
