To make a smore, 2 graham crackers, a piece of chocolate, and a marshmallow are needed. you have 5 graham crackers, 7 pieces of chocolate, and 5 marshmallows. using smores as your example, explain the concepts of limiting reactant, excess reactant, and theoretical yield.

Limiting reactant: graham crackers

Excess reactants: chocolate and marshmallows

Theoretical yield: 5/2 smores

Explanation:

When 2 graham crackers, a piece of chocolate, and a marshmallow are combined a smore is made.

You have 5 graham crackers, the following proportions must be satisfied:

2 graham crackers/5 graham crackers = 1 piece of chocolate/x piece of chocolate

x = 1*5/2 = 5/2 pieces of chocolate reacts

2 graham crackers/5 graham crackers = 1 marshmallow/y marshmallow

x = 1*5/2 = 5/2 marshmallows reacts

But you have 7 pieces of chocolate and 5 marshmallows, then the graham crackers are the limiting reactant, that is, when all crackers react, the reaction is finished. As a consequence the excess reactants are the pieces of chocolate and the marshmallows,  because at the time the reactant is completely consumed, there are still chocolate and marshmallow.

To compute the theoretical yield,  the following proportion must be satisfied (the limiting reactant is used):

2 graham crackers/5 graham crackers = 1 smore/z smore

z = 1*5/2 = 5/2 smores are made

1.consider the following balanced equation and answer parts a through. show calculations for each part.  

3 ag(s) + 4 hno3(aq) → 3 agno3(aq) + no(g) + 2 h2o(l)  

a. calculate the number of moles of agno3 produced by the reaction of 3 moles of ag with excess hno3. if the number to the left of the compound represents the number of moles of the compound which are present, then 3 moles of ag react with 4 moles hno3 to produce 3 moles agno3 (aq).

so the answer to a would be 3 moles.

b. calculate the number of moles of agno3 produced by the reaction of 108 grams of ag with excess hno3.  

i'm not sure how to plug in the grams of silver into an equation using moles to find how many moles are produced.

c. calculate the number of grams of agno3 produced by the reaction of 108 grams of ag with excess hno3  

d. calculate the number of moles of no produced as a byproduct of the reaction of 108 grams of ag with excess hno3.  

e. calculate the number of grams of no produced as a byproduct starting with 108 grams of ag and excess hno3.
