In summary, the conversation discusses finding the limiting reactant and theoretical yield for two reactions, one involving Na and Cl and the other involving Nitrogen and Hydrogen. The mole ratios of each reactant are necessary to find the limiting reactant. The question also clarifies the necessary information for finding the maximum amount of ammonia that can be synthesized.

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?
 

1. What is a limiting reactant?

A limiting reactant is the substance that is completely consumed in a chemical reaction, thus limiting the amount of product that can be formed.

2. How do I determine the limiting reactant?

To determine the limiting reactant, you must compare the amount of each reactant present in the reaction to the coefficients in the balanced chemical equation. The reactant with the smallest ratio of moles to coefficient is the limiting reactant.

3. What is theoretical yield?

The theoretical yield is the maximum amount of product that can be formed in a chemical reaction, assuming all of the limiting reactant is consumed and the reaction proceeds to completion.

4. How do I calculate the theoretical yield?

To calculate the theoretical yield, you must first determine the limiting reactant. Then, use the molar ratio from the balanced chemical equation to convert the moles of the limiting reactant to moles of product. Finally, multiply the moles of product by its molar mass to determine the theoretical yield in grams.

5. What is the purpose of calculating the limiting reactant and theoretical yield?

Calculating the limiting reactant and theoretical yield allows scientists to predict the maximum amount of product that can be formed in a reaction and helps them determine the most efficient way to carry out the reaction to achieve the desired amount of product.
