These statements describe three different reactions.
2 answers:
Answer: Option (b) is the correct answer.
Explanation:
When an atom shares electrons with another atom then it results in the formation of covalent bond.
Whereas when an atom transfer electrons from one atom to another then it results in the formation of ionic bond.
When nucleus of an atom splits then it represents nuclear fission reaction and energy is released during this process.
For example,
Therefore, we can conclude that out of the given options, the nucleus of an atom is split apart most likely release the greatest amount of energy.

Answer:
Pressure, P = 67.57 atm
Explanation:
<u>Given the following data;</u>
- Volume = 0.245 L
- Number of moles = 0.467 moles
- Temperature = 159°C
- Ideal gas constant, R = 0.08206 L·atm/mol·K
<u>Conversion:</u>
We would convert the value of the temperature in Celsius to Kelvin.
T = 273 + °C
T = 273 + 159
T = 432 Kelvin
To find the pressure of the gas, we would use the ideal gas law;
PV = nRT
Where;
- P is the pressure.
- V is the volume.
- n is the number of moles of substance.
- R is the ideal gas constant.
- T is the temperature.
Making P the subject of formula, we have;
Substituting into the formula, we have;
<em>Pressure, P = 67.57 atm</em>
