Exercise 1 : (7pts) Aqueous Solution
The teacher prepared three solutions in beakers A, B and C. She dissolved sugar
cubes tin different volumes of water as shown in document I.
Beaker A
Beaker B
Beaker C 2 liters
1 liter
1 liter
Document 1
1- Identify the solvent and the solute.
2- Indicate the type of the above solutions
3- Calculate the concentration of the above three solutions. Knowing that each
sugar cube has a mass of 2 g
4- Compare the concentration of the solution found in beaker A to that found in
Beaker B.
5- Deduce the nature of solutions found in beaker A and that found in beaker B.
6- A student said that solution in beaker A has the same sweet taste as the
solution in beaker C.
explain if his opinion is correct
7- Suggest a method to double the concentration of solution found in beaker A.
8- Suggest a method to dilute the solution found in beaker B into its half.​

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

the answer would be a

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
