Answer : 42.3 ml of a 0.266 M solution are required.
Solution : Given,
Molarity of solution 1 = 0.266 M
Molarity of solution 2 = 0.075 M
Volume of solution 2 = 150 ml = 0.150 L (1 L = 1000 ml)
Formula used :
where,
= Molarity of
solution 1
= Molarity of
solution 2
= Volume of
solution 1
= Volume of
solution 2
Now put all the given values in above formula, we get
(1 L = 1000 ml)
Therefore, 42.3 ml of a 0.266 M solution are required.
Answer : The correct option is, (D)
Explanation :
Option A reaction :
It is a combustion reaction. A reaction in which a hydrocarbon react with the oxygen to give product as carbon dioxide and water.
Option B reaction :
It is a combination reaction. A reaction in which the two or more reactants react to give a product.
Option C reaction :
It is a decomposition reaction. A reaction in which a reactant decomposes to form two or more products.
Option D reaction :
It is a single displacement reaction. It is a reaction in which the more reactive element displace the less reactive element. In this reaction, most reactive element chlorine displaces the less reactive element bromine.
Hence, the correct option is, (D)
