The Earth consists of four concentric layers: inner core, outer core, mantle and crust. The crust is made up of tectonic plates, which are in constant motion. Divergent, convergent, and transform.
Answer:
280 mL
Explanation:
Given data:
Mass of CuSO₄ = 55.75 g
Molarity of CuSO₄ = 1.25 M
Volume of CuSO₄ = ?
Solution:
First of all we will calculate the number of moles.
Number of moles:
Number of moles = mass / molar mass
Number of moles = 55.75 g/ 159.6 g/mol
Number of moles = 0.35 mol
Volume of CuSO₄:
Molarity = number of moles / volume in litter
1.25 M = 0.35 mol / volume in litter
Volume in litter = 0.35 mol / 1.25 M
Volume in litter = 0.28 L
Volume in milliliter:
0.28 L × 1000 mL/ 1 L = 280 mL

Iron and Nickle can be found in the outer core.
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.
