Answer:
14g
Explanation:
N2 + 2O2 => 2 NO2
Molar mass of O2 = 32g/mol
No of mol= 16/32 = 0.5 mol
2 moles of Oxygen react with 1 mol of N2
1 mol of oxygen react with X mol of N2
X = 0.5mol
Molar mass of N2 = 28g/mol
No of mol = mass/molar mass
Mass = 0.5 × 28 = 14g.
Friction occurs when two surfaces come into contact. Excess friction hinders movement, and it wastes energy. Friction refers to a force that opposes motion. It is important because it is applied in almost all life processes.
Answer:
As proteins vary widely in structures than that of nucleic acid there will be greater structural and functional diversity of proteins than nucleic acid.
Explanation:
Proteins are the macromolecules which have more structural diversity than any other macromolecules such as carbohydrate,lipid,nucleic acid.
The are 4 types of protein structure primary structure,secondary structure,tertiary structure and Quaternary structure.Due the existence of many types of structure various protein exhibit various functions.
On the other hand nucleic acid such as DNA has widely accepted secondary structure discovered by watson and crick.As a result there is no such structural diversity exist in nucleic acid.
