Answer: The correct answer is francium, radium and hassium.

Explanation:

Elements are distributed in groups and periods in a periodic table.

Elements that belong to same groups will show similar chemical properties because they have same number of valence electrons.

For the given options:

Option 1: Carbon, Silicon, and Tin

All these elements belong to Group 14. Thus, they will show similar chemical properties.

Option 2: Helium, Neon and Argon

All these elements belong to Group 18. Thus, they will show similar chemical properties.

Option 3: Francium, Radium and Hassium

Francium belongs to Group 1, radium belongs to Group 2 and Hassium belongs to Group 8. Thus, they will not show similar chemical properties.

Option 4: Manganese, Rhenium and Technetium

All these elements belong to Group 7. Thus, they will show similar chemical properties.

Hence, the correct answer is francium, radium and hassium.

The PH of a solution of Hcl is 2.find out the amount of acid present in a litre of the solution

Scrat [10]

Answer:

The solution is 10^-2 or 0.01M in HCl.

Explanation:

meaning of pH is "power of hydrogen".

what is the molar concentration of a HCl solution with pH=2?

Let say pH=2

[H+]=10^-2M

HCL is a strong acid that dissociates completely:

[H+]=[HCL]

Therefore solution is 10^-2 or 0.01M in HCL.

Ap sublevel has 3 electrons. How should they be arranged

galina1969 [7]

Answer:

C.)One electron in each p orbital

Explanation:

In a P-sublevel with 3 electrons, they should be arranged with one electron going into each p-orbitals.

This is in accordance with the Hund's rule of maximum multiplicity.

The rule states that "electrons go into degenerate orbitals or sub-levels(p,d and f) singly before paring up".

Since the p-orbital is 3-fold degenerate with a capacity to accommodate a maximum number of 6 electrons, given 3 electrons, they will follow the Hund's rule in order to fill the orbitals.

So one electron will go in each p - orbitals easily.

You are on an alien planet where the names for substances and the units of measures are very unfamiliar.

enyata [817]

Given that

1 skvarnick = 45 quibs

3 quibs = 7 sleps

Now if we have 45 quibs it means we have you have one skvarnick

three quibs = 7 sleps

so one quib = 7/3 sleps

so 45 quibs = 7 X 45 / 3 = 105 sleps
