The limiting reagent is Copper (Cu)
First, balance the reaction before determining the limiting reactant.
Cu + 2Ag
Cu(NO3)2 + 2Ag from NO3
Take the beginning material amount and calculate the number of moles of one of the products to identify the limiting reactant. The limiting reactant is the one that produces a product with the fewest moles.
5.50×1.00/2.00=2.75
The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be produced. Calculate how many moles of each reactant are present and contrast this ratio with the mole ratio of the reactants in the balanced chemical equation to get the limiting reactant.
Copper is the limiting reactant since there are only 2.50 mol of it and only 2.50 mol of AgNO3 will result from the reaction.

The reaction for formation of water vapour is as follows ;
2H2+ O2 —> 2H2O
Water vapour is in the gaseous form, at STP , 1 mol of any gas occupies 22.4 L volume
If 22.4 L occupied by 1 mol
Then amount of moles in 436 L - 1/22.4 x 436= 19.5 mol
Stoichiometry of O2 to H2O is 1:2
Amount of O2 moles reacted to formed H2O is -19.5 mol /2 = 9.75 mol
It is a combination reaction.
P + O₂ → P₂O₅
<h3 /><h3>What is a combination reaction?</h3>
Combination reactions are those in which two or more reactants combine to create a single product.
A synthesis reaction is another name for a combination reaction. The overall form of the reaction is as follows:
X + Y → XY
There can be a combination reaction between two elements, two compounds, or a compound and an element.
Examples:
H₂ + Cl₂ → 2HCl
P + O₂ → P₂O₅
C + O₂ → CO₂
