You have to use everything that is given since you have to know which is the limiting reactant. We find the limiting reactant by calculating the number of moles of each reactant and compare the number of moles. The limiting reactant would be the one that is consumed fully by the reaction.

The Environmental Protection Agency suggests using cold tap water for cooking instead of starting with warm tap water is because our drinking water is made out lead pipes, which is a serious risk to health.
Explanation:
- Lead is found throughout the environment in lead found in paint, air, soil, food and water.
- Lead can pose a significant risk to your health if too much of it enters your body.
- Lead enters drinking water primarily as a result of the corrosion.
- It also contains in materials containing lead like in the water distribution system and household plumbing.
- Lead in drinking rarely cause of lead poisoning can significantly increase a person’s total lead exposure.
- In particular the exposure of infants who drink baby formulas and concentrated juices that are mixed with water.
- EPA estimates that drinking water can make up to 20% or more of a person’s total exposure to lead which is dangerous.

Answer:
The phosphodiester connects the 3′ carbon of one nucleotide to the 5′ carbon of another nucleotide
Explanation:
The phosphodiester bond is a covalent bond where a phosphate group is attached to adjacent C through an ester bond, which is a consequence of a condensation reaction between the two sugar hydroxyl groups and the phosphate group.
The diester bond between phosphoric acid and two sugar molecules in the DNA and RNA skeleton binds two nucleotides forming polymers known as oligonucleotides.
The phosphodiester bond binds a C3` with a C5` in both DNA and RNA
(base)1-(sugar)-OH + HO-P(O)2-O-(sugar)-(base)2
------>
------> (base)1-(sugar)-O-P(O)2-O-(sugar)-(base)2
During the reaction of two of the hydroxyl groups in phosphoric acid with a hydroxyl group in two other molecules two ester bonds in a phosphodiester group are formed. A condensation reaction in which a water molecule is lost generates each ester bond.
