Answer:
10 electrons
The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
The answer is A hopefully it is ok ✅
Solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. Solubility of a gas is inversely proportional to temperature.
So, the solubility of carbon dioxide gas in water is increased by increasing the partial pressure of carbon dioxide and by decreasing the temperature.
Answer : The energy change for the reaction is CsCl is, 95 KJ/mole
Explanation :
The steps involved in the formation of :
(1) Conversion of gaseous potassium atoms into gaseous potassium ions.
= ionization energy of potassium = 419 kJ/mol
(2) Conversion of gaseous bromine atoms into gaseous bromine ions.
= electron affinity energy of bromine = -324 kJ/mol
The overall reaction will be:
To calculate the overall energy change the expression used is:
Now put all the given values in this equation, we get:
Therefore, the energy change for the reaction is CsCl is, 95 KJ/mole
Particles are moving from regions of high concentration to low concentration. Hence, option A is correct.
<h3>What is diffusion?</h3>
Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration.
Diffusion results from the random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration.
This process can neither be stopped nor reversed. It occurs when the medium surrounding the cell has a higher water concentration than the cell.
Hence, option A is correct.
