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.

Classify each of these reactions pb(no3)2+nicl2=pbcl2+ni(no3)2
maxonik [38]

The reaction Pb(NO3)2(aq) + NiCl2(aq)---------> PbCl2(s) + Ni(NO3)2(aq) is a precipitation reaction.

A chemical reaction is said to occur when two or more substances are combined to produce new substances. Chemical reactions are classified based on the kind of change taking place in the reaction.

In the reaction;

Pb(NO3)2(aq) + NiCl2(aq)---------> PbCl2(s) + Ni(NO3)2(aq)

We can see that a solid is formed when lead II nitrate reacts with nickel II chloride. This is a precipitation reaction.

An open manometer connected to a tank of argon has a mercury level of 83 mm higher in the atmospheric arm. If the atmospheric pr
disa [49]

Answer:- 88 kPa.

Solution:- The level of mercury in the atmospheric arm that is the open arm is 83 mm. It indicates the gas pressure is 83 mm higher than the atmospheric pressure.

gas pressure = height of mercury level in open tube in mm + atmospheric pressure

Let's convert this 83 mm pressure to kpa since the atmospheric pressure is given in kPa and the answer is also asked to report in kPa.

mmHg is converted to atm first and then atm is converted to kpa.

760 mmHg = 1 atm

and 1 atm = 101.325 kPa

83mmHg(\frac{1atm}{760mmHg})(\frac{101.325kPa}{atm})

= 11 kPa

Atmospheric pressure is 76.9 kPa.

gas pressure = 11 kPa + 76.9 kPa

gas pressure = 87.9 kPa

If we think about sig figs rule then 87.9 should be round to 88 as in addition we go with least number of decimal places. 11 kPa does not have any decimal places and so the gas pressure is 88 kPa.
