Question

What does the symbol '∆' represent in a chemical equation ?

• A. Catalyst
• B. Precipitate
• C. Heating
• D. Physical state

Answer 1

The Correct Option is C

To solve the problem, we need to understand the meaning of the symbol "Δ" in a chemical equation.

1. Understanding the Symbol Δ:
In a chemical equation, the symbol "Δ" represents heating. It is used to indicate that the reaction occurs under the influence of heat.

2. Evaluate the Options:
- Option (A): Catalyst – The catalyst is typically written above or below the arrow, not represented by "Δ".
- Option (B): Precipitate – A precipitate is usually written as a product or reactant, not with "Δ".
- Option (C): Heating – This is correct, as "Δ" indicates that heat is applied during the reaction.
- Option (D): Physical state – Physical states of reactants/products are indicated by symbols like (s), (l), (g), or (aq), not "Δ".

Final Answer:
The correct answer is option (C): Heating.
