Chemical equations show the ratio of reactants and products involved in a chemical reaction. For example, 2 H2 + O2 → 2 H2O. How do balanced equations
satisfy the Law of Conservation of Mass?*
A. The number of reactant molecules equals the number of product molecules.
B. Every atom present in the reactants is also present in the products.
O C. The number of reactant molecules adds up to the number of product molecules.
D. The energy stored in bonds before and after the reaction is the same.

The number of reactant molecules equal s to the number of product molecules is right one

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.  

explanation:

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
