</span><span>In the activity "Drop it Like its "hot spot", it can be seen that the surface of the paper which is directly in contact with the test tube became wet considering that the paper represents the earth's crust and the water is the magma coming from the earth's . </span>
Colligative properties are usually used in relation to solutions.
Colligative properties are those properties of solutions, which depend on the concentration of the solutes [molecules, ions, etc.] in the solutions and not on the chemical nature of those chemical species. Examples of colligative properties include: vapour pressure depression, boiling point elevation, osmotic pressure, freezing point depression, etc.
For the question given above, the correct option is D. This is because the statement is talking about freezing point elevation, which is not part of colligative properties.
Answer : The number of moles of formed are, 0.69 moles.
Explanation : Given,
Moles of = 0.345 mol
Now we have to calculate the moles of
The balanced chemical equation is:
From the balanced reaction, we conclude that
As, 1 mole of react to give 2 moles of
So, 0.345 mole of react to give mole of
Therefore, the number of moles of formed are, 0.69 moles.
Answer:
Aufbau Principle: Electrons occupy orbitals of lower energy first.
Pauli Exclusion Principle: An orbital can hold only two electrons and they must have opposite spin.
Hund's Rule: Electrons fill each orbital singly before any orbital gets a second electron.
