Which statement accurately describes the products of a reaction? A.)substance that do not participate in a reaction.
B.) substances that are used in a reaction.
C.) new substances that are present at the end of a reaction.
D.) substances that were not used up in a reaction.

C.) new substances that are present at the end of a reaction.

Explanation:

In a chemical reaction, substances are combined to form other substances. The substances, in a chemical reaction, that are combined or used up are called REACTANTS while those substances that are synthesised newly at the end of the reaction are called PRODUCTS.

For example, in the chemical reaction between carbon dioxide and water in photosynthesis to form glucose and oxygen as follows:

6CO2 + 6H2O --> C6H12O6 + 602

CO2 and H2O are the REACTANTS because they are the combined substances.

C6H12O6 and 02 are the PRODUCTS because they are new substances present at the end of the reaction.

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:

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
