Answer:
use n=m/M (moles=mass/molar mass) to find out how many moles of C2H6 there are in 60g
Explanation:
Answer:
Metals
1) Sodium : It is used in the formation of table salt i. e. sodium chloride.
2) Copper : It is used in the wires of electricity due to better conduction.
3) Silver : It is used in wires and for making jewelry.
4) Aurum: It is used for making jewelry.
Non metals
1) Chlorine : It is used in the production of sodium chloride salt which is used in foods.
2) Flourine : It is used in making toothpaste.
3) Hydrogen : It is used in the formation of acids.
4) Oxygen : It is widely used in the production of steel and plastic.
Answer:
Colloidal dispersion or emulsion
Explanation:
The colloid of a liquid in liquid (both dispersed phase and dispersion medium are liquids) is known as emulsion or colloidal dispersion.
We know that oil and water are immiscible liquids. In order to make them miscible we have have add emulsifying agents.
An emulsifying agent has a long non polar hydrocarbon chain (in general) and a polar head.
For example salts of fatty acids.
The polar head is hydrophilic and non polar tail is hydrophobic.
It causes the miscibility of the two polar and non polar liquids
