Gnoma [55]3 years ago

Answer:

5

Explanation:

The maximum numbers of d orbitals are 5. These are named as dz², dxy, dyz, dzx, dx² - y².

The number of maximum electrons accommodate in d orbitals are,

l = 2

2 ( 2(2) + 1)

2( 4 + 1)

10

so maximum electrons in d subshell are 10.

The 1st and second energy level do not have d orbitals. Third energy level in addition to s and p orbitals contain d orbitals.

Energy level           sublevel              N of orbitals                  No of electrons

   1                               s                            1                                     2    

  2                               s                             1                                    2

                                   p                            3                                  6 (total=8)

  3                                s                            1                                     2

                                    p                           3                                    6

                                   d                             5                                10 (total=18)

What is the volume of 0.410 moles of co2 at STP​
inna [77]

Answer: 9.18 Litres

Standard Temperature and Pressure (STP). Think of this as the perfect environment where the Temp. is 0°C or 273 Kelvin and Pressure is always 1 atm. This is only true in STP.

This question uses the Ideal Gas Equation:

PV=nRT

P= 1 atm

V = ??

T = 273 K (always convert to Kelvin unless told otherwise)

n = 0.410 mol

R = 0.0821 L.atm/mol.K

What R constant to use depends on the units of the other values. (look at the attachments) The units cancel out and only Litres is left. You simply multiply the values.
