H_{2} O_{2} symbolizes a molecule of a compound

Answer: Option A

<u>Explanation: </u>

A molecule contains one or more atoms which exists free in nature. It can be monoatomic (single atom), Na, Cu, C, N, H, O, etc. and diatomic (containing 2 atoms), are of two types

  • Homo-diatomic- same atoms (H_{2}, O_{2}, F_{2}, B r_{2}, C l_{2}, etc.)
  • Hetero-diatomic- different atoms (HCl, HF, NO, NaCl, etc.)
  • Tri-atomic (containing 3 atoms) \mathrm{H}_{2} \mathrm{O}, \mathrm{N}_{2} \mathrm{O}, \mathrm{Na}_{2} \mathrm{O}, etc.
  • Polyatomic (containing many atoms) H_{2} S O_{4}, P_{2} O_{5}, H N O_{3}, etc.

A compound consists of more one atom which are chemically combined in a fixed composition. So, here we see H_{2} O_{2} is the molecule which symbolizes a compound since it contains more than one element, H and O present in it.

What is the entropy change in the environment when 5.0 MJ of energy is transferred thermally from a reservoir at 1000 K to one a
Leni [432]

Answer:

The entropy change in the environment is 3.62x10²⁶.

Explanation:

The entropy change can be calculated using the following equation:

\Delta S = \frac{Q}{k_{B}}(\frac{1}{T_{f}} - \frac{1}{T_{i}})

Where:

Q: is the energy transferred = 5.0 MJ

k_{B}: is the Boltzmann constant = 1.38x10⁻²³ J/K  

T_{i}: is the initial temperature = 1000 K

T_{f}: is the final temperature = 500 K

Hence, the entropy change is:

\Delta S = \frac{5.0 \cdot 10^{6} J}{1.38 \cdot 10^{-23} J/K}(\frac{1}{500 K} - \frac{1}{1000 K}) = 3.62 \cdot 10^{26}                                    

Therefore, the entropy change in the environment is 3.62x10²⁶.

I hope it helps you!
