Answer: The shape of an orbital describes a surface that encompasses about 90% of the probability of finding an electron around a nucleus.
Explanation:
An orbital is described as a region in Space around which there is a high probability of finding an electron.
Orbitals possess various shapes. The shape of an orbital describes the region around the nucleus within which an electron in a given energy level may be found with a greater probability.
Answer:
Gay-Lussac's law states that in a closed system of fixed volume, as the temp and the pressure of the gas increases.
Explanation:
Temperature is a measure of the average kinetic energy of a substance. As the temp of a substance rises, its molecules are moving faster
Answer: The pressure of the gas is 0.225 atm.
Explanation: To calculate the pressure of the gas, we use Boyle's Law.
Boyle's Law states that pressure is inversely proportional to the volume of the gas at constant temperature.
Mathematically,
Or,
where,
are the initial pressure nd volume.
are the final pressure andvolume
Initial conditions:
Final conditions:
Conversion factor: 1L = 1000mL
Putting values in above equation, we get:
Answer:
What is the composition of air?
Explanation:
You would expect Na to have the larger ionic radius
