Question

What are the requirements before you can compare the energy for 2 compounds?

a) Equal mass
b) Same temperature
c) Similar molecular structure
d) Standardized pressure

Answer 1

Before comparing the energy of two compounds, several requirements need to be met: equal mass, same temperature, similar molecular structure, and standardized pressure.

Step-by-step explanation:

Before comparing the energy of two compounds, there are several requirements that need to be met:

1. Equal mass: The compounds should have the same mass in order to compare their energies accurately.
2. Same temperature: The compounds must be at the same temperature to ensure that the kinetic energy of their molecules is comparable.
3. Similar molecular structure: The compounds should have similar molecular structures so that their intermolecular forces and energy interactions can be properly compared.
4. Standardized pressure: The pressure conditions for both compounds should be standardized to eliminate the effect of pressure on their energy comparisons.
