Question
Energy change in a chemical reaction is represented by the symbol __________________.
Question 4
Answer
A. H
B. ΔT
C. ΔH
D. ΔE
Solution
Determine the Correct Symbol
-
Review the Options
- A. H
- B. ΔT
- C. ΔH
- D. ΔE
-
Identify Relevant Concepts
- In thermodynamics and chemistry, energy changes during a chemical reaction are typically represented by the change in enthalpy (ΔH) or the change in energy (ΔE).
-
Evaluate Each Option
- A. H: This symbol usually represents enthalpy, but not the change.
- B. ΔT: This symbol refers to the change in temperature, not energy change.
- C. ΔH: This represents the change in enthalpy, which corresponds to energy change in a reaction.
- D. ΔE: This represents the change in energy, but is less commonly used than ΔH.
Conclusion
ΔH (the change in enthalpy) is the most widely accepted representation of energy change in a chemical reaction.
Final Answer
C. ΔH
