The given reaction is exothermic,
X + Y ----> XY + Heat
Heat is a product. So, if the temperature is increased, the equilibrium is shifted towards the reactants. So, the <u>[X] increases</u>.
Answer:Molarity tells us the number of moles of solute in exactly one liter of a solution. (Note that molarity is spelled with an "r" and is represented by a capital M.) We need two pieces of information to calculate the molarity of a solute in a solution: The moles of solute present in the solution
Explanation:
Answer:
(a) Concentrated sulphuric acid is called the king of chemicals as it is a very strong acid and is highly corrosive. ... (c) If water is added to sulphuric acid, then a large amount of heat is evolved. This changes water to steam, which can splash the acid. Hence, it is dangerous

Answer:
The correct option is: A. 0.168 M
Explanation:
Chemical reaction involved:
5 Fe²⁺ (aq) + MnO₄⁻ (aq) + 8 H⁺ (aq) → 5 Fe³⁺ (aq) + Mn²⁺ (aq) + 4 H₂O
Given: <u>For MnO₄⁻ solution</u>-
Number of moles: n₁ = 1, Volume: V₁ = 20.2 mL, Concentration: M₁ = 0.0250 M;
<u>For Fe²⁺ solution</u>:
Number of moles: n₂ = 5, Volume: V₂ = 15 mL, Concentration: M₂ = ?M
<u><em>To find out the concentration of Fe²⁺ solution (M₂), we use the equation:</em></u>
<u>Therefore, the concentration or molarity of Fe²⁺ solution: </u><u>M₂ = 0.168 M</u>
