I'm sure it will help.
Answer:
C. slightly basic
Explanation:
0-7 = acidic
7 = neutral
7-14 = basic
- Since the pH is just over 7, the answer would be slightly basic.
- Hope this helps! Please let me know if you need a further explanation.
True is the answer as at 100 Celsius water boils
The following are the answers:
=oxygen equals to a charge of 2-
number of atoms is -24
=Mn equals to the charge of +3
Mn= 3+3x-24=0
let x be the charge of Cl, so:
23-3=3x
20/3=x
=6.67 or 7
x= 7
= Cl has a charge of +7
You are right about your answers
Answer:
1=hydroxyl of phosphate
2=hydroxyl
Explanation:
Nucleic acid is the condensation polymer of nucleotide. Nucleotides are link together through ester bond. The hydroxyl group of phosphate on one nucleotide goes to condensation reaction with the hydroxyl group of another nucleotide. This is chain process, a large molecule of nucleic acid is formed. It is also called polynucleotide.
RNA and DNA are formed by the nucleic acid. The building block of nucleic acid made up of three chemicals.
- Pentose sugar
- Base
- Phosphate
Pentose sugar:
The sugars present in DNA and RNA is pentose. In DNA this sugar is deoxyribose while in case of RNA this is ribose sugar. The hydroxyl groups are present on these sugars. Ribose consist of four hydroxyl group while deoxyribose consist of three hyrdroxyl group. These react with phosphoric acid and carboxylic acid and form ester.
Base:
RNA and DNA are consist of four bases:
DNA= Adenine, guanine, thymine, cytosine
RNA= Adenine, guanine, uracil, cytosine
Phosphate:
The inorganic acid H3PO4 is present. The hydroxyl group present on it undergoes the reaction with amines and alcohol to form amide and ester respectively.
