GENERAL PRINCIPLES AND PROCESSES OF ISOLATION OF ELEMENTS Quiz-17

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. All ores are minerals, while all minerals are not ores because
  •  Minerals are complex compounds
  •  The minerals are obtained from mines
  •  The metal cannot be extracted economically from all the minerals
  •  All of the above are correct
Solution
Metals can not be extracted from all the minerals that is why all minerals are not ores.

Q2. The electrolytic method of reduction is employed for the preparation of metals that
  •  Are strongly electropositive
  •  Are weakly electropositive
  •  Are moderately electropositive
  •  From oxides
Solution
In electrolytic reduction, the oxides of highly electropositive metals are reduced at very high temperature

Q3. The lining in blast furnace are made up of:
  •  Graphite
  •  Silica
  •  Fireclay bricks
  •  CaCO3
Solution
It is a fact.

Q4. Chile salt petre is an ore of
  •  Magnesium
  •  Bromine
  •  Sodium
  •  Iodine
Solution
Chile salt petre(NaNO3) is the nitrate ore of sodium

Q5.Cassiterite is concentrated by
  •  Liquation
  •  Floatation
  •  Electromagnetic separation
  •  Levigation
Solution
 It is a fact.

Q6. Which of the following metal is sometimes found native in nature?
  •  Mg
  •  Cu
  • Al
  •  Fe
Solution
Copper is found in native as well as in combined state.

Q7.From which form of iron, other forms of iron can be produced?
  •  Cast iron
  •  Wrought iron
  •  Pig iron
  •  Steel
Solution
Cast iron, wrought iron and steel may be produced from pig iron.

Q8.Blister copper is obtained by:
  •  Bessemerisation
  •  Roasting
  •  Poling
  •  Refining
Solution
In Bessemerisation, the molten mass is run into sand moulds and allowed to solidify, when it gives out dissolved SO2 leaving blister type appearance on copper which is popularly known as blister copper.

Q9.The mass of carbon anode consumed (giving only carbon dioxide) in the production of 270 kg of aluminium metal from bauxite by the hall process is(Atomic mass of Al=27)
  •  180kg
  •  270 kg
  •  540 kg
  •  90 kg
Solution
In Hall and Heroult process, 2Al2 O3→4Al+3O2 4C+3O2→2CO2+2CO↑ 2Al2 O3+4C→4Al+2CO2+2CO Only for removal of CO2, following equation is possible 2Al2 O3+ 3C → 4Al+ 3CO2 3×12=36 4×27=108 ∵For 108 g of Al, required amount of C=36g ∴ For 270 g of required amount of C=36/108×270=90g

Q10. Formula of magnetite is
  •  Fe3 O4
  •  Fe2 O3
  •  FeS2
  • FeCO3
Solution
It is a fact.
