Multiple choice chemistry metals physical properties of metals and non-metals some physical properties of metals general characteristics and uses of metals

The concentration of matter in a material is:

  1. volume

  2. mass

  3. density

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

For a pure chemical, the mass concentration is equal to its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called density of a component in a mixture.

Multiple choice biology reproductive health stds and infertility gm crops biotechnology

Bull semen for the purpose of artificial insemination is stored in 

  1. Ice

  2. Liquid oxygen

  3. Liquid nitrogen
  4. Liquid CO$ _2$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Artificial insemination is a globally accepted method of breeding cattle and is also effective for other species. Semen can be stored deep-frozen in liquid nitrogen, in a chilled liquid form or at room temperature. Its low temperature of $-196^0$C and inert caracteristics prevent the deterioration of biological quality. Hence, option C is correct.

Multiple choice chemistry composition of matter physical properties of non-metals uses of metals and non metals physical properties of metals and non-metals

Compare metals and non-metals with particular emphasis on solubility:

  1. Both dissolve in solvent

  2. None of them dissolve in solvent

  3. Metal dissolve while non-metal do not dissolve in solvent

  4. Non-metal dissolve while metal do not dissolve in solvent
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
MetalsThey do not dissolve in solvents except by chemical action. Non-metalsThey dissolve in solvents and can be re-obtained by evaporation. Example: sulphur in carbon disulphide.

The non-metal which is liquid at room temperature is:

  1. chlorine

  2. fluorine

  3. bromine

  4. iodine
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bromine is the only non-metal which is liquid and diatomic molecule at room temperature. 

It is a dense, reddish-brown liquid evaporating at standard temperature and pressure to give an orange vapour. It is one of the only two elements on the periodic table that are liquids at room temperature other than mercury.

Hence, option $C$ is correct.

Non-metals are present in which state?

  1. Solid

  2. Liquid

  3. Gaseous

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Answer: all of the above 

Most of metal exist in two out of three states of matter at room temperature
Eg: gases- oxygen,  solid-carbon

Only bromine exist in liquid state at room temperature.

Which among the following non-metal is liquid at room temperature?

  1. Chlorine

  2. Bromine

  3. Mercury

  4. Phosphorous
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mercury and bromine both are present in liquid state at room temperature but mercury is metal and bromine is non-metal.

So, liquid non-metal at room temperature is bromine.

Multiple choice chemistry matter around us measurement of properties effect of temperature and pressure on states of matter general introduction: importance and scope of chemistry

Which of the following is not a basic physical quantity?

  1. Length

  2. Time

  3. Density

  4. Amount of substance
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Basic physical quantities are those that are physical fundamental units. There are seven basic fundamental quantities: Length, mass, time, electric current, amount of substance, luminous intensity & temperature. The quantities which are derived with the help of these basic physical quantities are called derived quantities. They are density, volume, pressure, force, etc.
