CHEMISTRY IN EVERYDAY LIFE QUIZ-7
Dear Readers,The one subject in NEET which is candidates who can easily attain good marks is Chemistry. That's the reason, often, one doesn’t pay notice and choose to compromise it. But if one wants to rank above others, the tip is to be thorough with NEET chemistry concepts. The understanding of reactions and definite basic understanding is what requires major attention in Chemistry but once done it only gets simpler from there. The main focus on the to-do list should be on getting a hang of the NCERT syllabus of NEET chemistry.
Q1. Chloroquine is an example of:
Solution
Q2.Acetoxy benzoic acid is:
Solution
(b) Acetyl salicylic acid is also called acetoxy benzoic acid (aspirin).
(b) Acetyl salicylic acid is also called acetoxy benzoic acid (aspirin).
Q3. Which of the following is an antipyretic?
Solution
Q4. An example of a liquid propellant is:
Solution
(a) Liquid propellants: These include fuels such as kerosene, alcohol, hydrazine or liquid hydrocarbon mixed with an oxidiser such as liquid oxygen, dinitrogen tetraoxide(N2O4) or nitric acid. These are also classified into two categories: (i) Monopropellants : The single liquid compounds used as propellants are those which decompose on heating to give out gases. (ii) Biliquid propellants: Biliquid propellant: A double base propellant is a high strength, high modulus gel of cellulose nitrate (gun cotton) in glyceryl trinitrate or a similar solvent. Following are the combinations of liquid propellants and oxidisers (supporter of combustion) usually used: (i) Synthetic rubber or cellulose based compounds and liquid oxygen. (ii) Liquid hydrogen and liquid oxygen. (iii) Kerosene and liquid oxygen. (iv) Hydrazine and nitric acid. (v) Methyl hydrazine and dinitrogen tetraoxide. 4CH4 NHNH2┬(Methyl hydrazine ) + 5N2 O4┬(Dinitrogen tetraoxide) ⟶4CO2+9N2+12H2 O. N2 H4+O2⟶N2+2H2 O; ∆H= ⎼Heat.
