m moles 120 40 – 80 – 40
Heat liberated from reaction
= 40 × 10–3× 57 × 103 J …(1)
Heat gained by solution =
Mass of solution
Heat gained by solution
From eq (1) and eq (2)
Heat liberated = Heat gained
10–2
(Rounded off to the nearest integer)
So, the answer is 54°C.
A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm.
For example, salt and sugar is a good illustration of a solution. A solution can be categorized into several components.
The solutions can be classified into three types:
On the basis of the amount of solute dissolved in a solvent, solutions are divided into the following types:
