<span>Most living things on Earth are made of carbon.
Living things need carbon in order to live, grow, and reproduce.
Carbon is a finite resource that cycles through the Earth in many forms.
This makes carbon available to living organisms and remains in balance with other chemical reactions in the atmosphere and in bodies of water like ponds and oceans.</span>
Answer: B2H6 (g) + 3O2 (g) → B2O3 (s) + 3H2O (g) (ΔH = -2035 kJ/mol) 3H2O (g) → 3H2O (l) (ΔH = -132 kJ/mol) 3H2O (l) → 3H2 (g) + (3/2) O2 (g) (ΔH = 858 kJ/mol)
Explanation: ??
Change of state occurs when heat is supplied or removed from a substance.
<h3>What is change of state?</h3>
Change of state refers to the changes that occur when a substance changes from one physical state to another due to changes in its temperature.
It is also known as phase change.
Phase Change can also be defined as change from one state to another without a change in chemical composition.
Some of the phase changes include:
- Freezing: when liquid changes to solid
- Condensation: when gas changes to liquid
- Melting: when solid changes to liquid
- Evaporation: when liquid changes to gas
The other terms associated with phase change include:
- Boiling point: the temperature at which vapor pressure becomes high that causes bubbles to form inside the body of the liquid
- Freezing point: temperature wherein a liquid solidifies
- Melting point: the temperature at which solid turns into a liquid.
