<h2>Given reaction:
</h2><h2>C2H2 + 2H2 → C2H6
</h2><h2>This reaction represents: Combination reaction </h2>
Explanation:
When two or more substances react and form some new substance it is called as chemical reaction .
A + B --> C + D
(reactants ) (products )
Types of chemical reaction
we come across different types of reactions that occur in nature .
Out of them , combination is also one type
Combination reaction
It is a reaction ,when two or more reactants react to form single product .
i.e A+B-----AB(IN THIS ONE SINGLE PRODUCT IS FORMED )
- This reaction can be between element element , element compound or compound compound .
LIKE : H₂+Cl₂------HCL
(E) (E) (PRODUCT )
SO₂+O₂----SO₃
© (E) (PRODUCT )
CO₂+H₂O----H₂CO₃
In the above asked equation :
C₂H₂ + 2 H₂ --> C₂H₆
- The ethane is formed by combination reaction
- This reaction obeys law of conservation of mass as it is balanced .
<u>Answer: </u>The correct answer is Option A.
<u>Explanation:</u>
The molecule given in the question is HCl which forms a polar covalent bond.
A polar bond is defined as the bond present between two elements with different electronegativity value. The element which has higher electronegativity value, attracts the shared pair of electrons towards itself and forms a dipole. A polar molecule is dissolved more in a polar substance than in non-polar substance.
In the given compound, the electronegativity of chlorine is more than hydrogen and attracts the shared pair of electron more towards itself and hence is a polar molecule.
A non-polar bond is defined as the bond which is formed between the elements having same electronegativity value. No dipole is created in these type of bonds. Here, the electrons are shared equally.
From the above information, the correct answer is Option A.
Answer: Option (c) is the correct answer.
Explanation:
A binary mixture is defined as the mixture which contains two components in the aqueous medium. The two components are solute and solvent.
And, volatility is defined as the ability of a liquid solution or substance to readily change into vapors.
For a binary solution the expression for relative volatility is as follows.
= 
where, 
= relative volatility of more volatile component i
= vapor-liquid equilibrium concentration of component i in the vapor phase
= vapor-liquid equilibrium concentration of component i in the liquid phase
= vapor-liquid equilibrium concentration of component j in the vapor phase
= vapor-liquid equilibrium concentration of component j in the liquid phase
So, when > 1 then separation by distillation is easier in nature.
Thus, we can conclude that in order to separate the components of a binary mixture, the relative volatility should be greater than unity.
