Answer:

electron configuration of carbon: 1s²2s²2p²

Explanation:

The electron configuration of atoms (or ions) is depicted based on the Aufbau principle according to which electrons are added to various orbitals such that the orbital with the lowest energy gets occupied first followed by the next higher orbital.

The energy ordering of orbitals from the lowest to the highest is:

1s < 2s < 2p < 3s < 3p < 4s  < 3d ....

s orbitals can accommodate a maximum of 2 electrons

p orbitals = 6 electrons

d orbitals = 10 electrons

Now, the atomic number of carbon = 6

Since it is neutral, the atomic number = number of electrons = 6

Based on the Aufbau principle the electron configuration of C would be

1s²2s²2p²

I think I have done a question like this before and i'm pretty sure your answer would be the 2nd one 1s22s22p4. I'm not 100% sure but try it at least.

what type of element can turn into both solid and liquid form depending on the temperature of its surroundings ?​
lorasvet [3.4K]

<em>Answer:</em>

<em>An Atom can turn into both solid and liquid form depending on the temperature of its surroundings </em>

<em>Explanation:</em>

<em>Scientists have discovered a new state of physical matter in which atoms can exist as both solid and liquid simultaneously. Researchers have found, however, that some elements can, when subjected to extreme conditions, take on the properties of both solid and liquid states.</em>

Determine the molar concentration of na+ and po4 3- in a 2.25 M Na3 PO4 solution
muminat

Answer:

A. The concentration of Na^+ in the solution is 6.75 M.

B. The concentration of PO4^3- in the solution is 2.25 M.

Explanation:

We'll begin by writing the balanced dissociation equation for Na3PO4.

This is illustrated below:

Na3PO4 will dissociate in solution as follow:

Na3PO4(aq) —> 3Na^+(aq) + PO4^3-(aq)

Thus, from the balanced equation above,

1 mole of Na3PO4 produce 3 moles of Na^+ and 1 mole of PO4^3-

A. Determination of the concentration of Na+ in 2.25 M Na3PO4 solution.

This can be obtained as follow:

From the balanced equation above,

1 mole of Na3PO4 produce 3 moles of Na^+.

Therefore, 2.25 M Na3PO4 solution will produce = (2.25 x 3) /1 = 6.75 M Na^+.

Therefore, the concentration of Na^+ in the solution is 6.75 M

B. Determination of the concentration of PO4^3- in 2.25 M Na3PO4 solution.

This can be obtained as follow:

From the balanced equation above,

1 mole of Na3PO4 produce 1 mole of PO4^3-

Therefore, 2.25 M Na3PO4 solution will also produce 2.25 M PO4^3-.

Therefore, the concentration of PO4^3- in the solution is 2.25 M.
