Which type of polymer is rna? a protein a nucleic acid a carbohydrate a starch

The correct answer is a nucleic acid.

Explanation:

Full form of RNA is ribonucleic acid. It is a nucleic acid which is present in all the living cells.

The role of RNA is basically to act as a messenger which carries instructions from DNA to control the synthesis of proteins.

It is a polymer of nucleic acid. There are 4 nucleic acids which combine to form RNA. The four nucleic acids are: Adenine (A), Guanine (G), Uracil (U) and Cytosine (C).

Adenine bonds with Uracil and Guanine bonds with Cytosine.

Hence, the correct answer is a nucleic acid.

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.
