Answer:

The 3p orbital of the element will be completely filled if it forms 3 bonds with other atoms.

Explanation:

Phosphorus is a element of 15 group and 3 period.

The electronic configuration of the phosphorous is:

1s²2s²2p⁶3s²3p³

<u>The 3p orbital of phosphorous is singly filled by 3 electrons and if it shares more 3 electrons with other atom, its valence shell will be completely filled which makes it more stable. Hence, phosphorus makes 3 bonds like in PH₃ and PCl₃ .</u>

The MO diagram of CN is similar to N2. Based on the molecular orbital energy-level diagram of CN, which of the following stateme
liubo4ka [24]

Answer:

Nitrogen molecule (N2)

The electronic configuration of nitrogen (Z=7) = 1s2 2s2 2px12py12pz1.

The total number of electrons present in the nitrogen molecule (N2) is 14.

In order to maximize energy, these 14 electrons can be accommodated in the different molecular orbitals.

N2: KK'(σ2s)2 (σ*2s)2 (π2Px)2 (π2py)2 (σ2pz)2

Here (σ1s)2 (σ*1s)2 part of the configuration is abbreviated as KK’, which denotes the K shells of the two atoms. In calculating bond order, we can ignore KK’, as it includes two bonding and two antibonding electrons.

The bond order of N2can be calculated as follows:

Here, Nb = 10 and Na = 4

Bond order = (Nb−Na) /2

B.O = (10−4)/2

B.O = 3

So your answer should be C3.

calculate the ph of the resulting solution if 17.0 ml of 0.170 m hcl(aq) is added to 22.0 ml of 0.170 m naoh(aq).
Natalka [10]

The pH of the finsl solution is equal to <u>2.93</u>

Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.

C₁ = 0.170 m

V₁ = 17 ml = 0.017 L

C₂ = 0.170 M

V₂ = 22 ml = 0.022 L

C₁V₁ =C₂V₂

0.170× 0.017 L = 2.89 × 10⁻³  ------------- HCl

0.170× 0.022 L = 3.74 × 10⁻³  ------------ NaOH

⇒ 3.74 × 10⁻³  -  2.89 × 10⁻³ = 0.85 × 10⁻³

⇒ 3 + log 0.85

⇒ 3 + -0.07

⇒ pH = <u>2.93</u>

The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.

The pressure and temperature inside a bike tires 10 ATM and 10 K receptively. What will the pressure be come in the tire when th
pishuonlain [190]

Answer:

P = 20atm

Explanation:

P1 = 10atm

T1 = 10K

P2 = ?

T2 = 20K

This question requires the use of pressure law which states that the pressure of a fixed mass of gas is directly proportional to its temperature provided its volume remains constant

Mathematically,

P = kT, k = P / T

P1 / T1 = P2 / T2 = P3 / T3=........=Pn / Tn

P1 / T1 = P2 / T2

P2 = (P1 × T2) / T1

P2 = (10 × 20) / 10

P2 = 20atm

The final pressure of the gas is 20atm
