a) Crystallization :- Crystallization is a chemical process in which the solid-liquid separation technique occurs. This process causes mass transfer of a solute from the liquid solution to a pure solid crystalline phase.

b) Radical :- A radical is an atom of an element or a group of atoms of different elements that behaves as a single unit with a positive or negative charge on it.

c) Mixture :- A mixture is a combination of two or more substances (elements or compounds) which is not done chemically.

Answer:

(a) Crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.

(b) A radical is an atom of an element or a group of atoms of different elements that behaves as a single unit with a positive or negative charge on it.

(c) Mixtures are constituted by more than 1 kind of pure form known as substance. There are 2 types of mixture:-

(i) homogeneous

A mixture in which the constituents are uniformly distributed throughout without any clear boundary of separation

(ii) Heterogeneous

A mixture in which constituents don't have uniform composition and has a visible boundary of separation.

6) A volume of 473 mL of oxygen was collected at 27°C. What volume would the oxygen occupy at
sertanlavr [38]

Answer : The volume of oxygen occupy at 173° would be, 703.2 mL

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=473mL\\T_1=27^oC=(27+273)K=300K\\V_2=?\\T_2=173^oC=(173+273)K=446K

Now put all the given values in above equation, we get:

\frac{473mL}{300K}=\frac{V_2}{446K}\\\\V_2=703.2mL

Therefore, the volume of oxygen occupy at 173° would be, 703.2 mL

The distance between particles______when the temperature increases and
LekaFEV [45]

Answer:

increases

decreases

Explanation:

The distance between particles increases when the temperature increases and decreases when temperature decreases.

  • Temperature changes in a system causes the particle of such system to behave in different ways.
  • When particles gain heat energy as their temperature increases, they begin to move further apart.
  • As their temperature reduces they tend to coalesce.
