What is the maximum number of orbitals in a p sublevel?
a. 2
b. 3
c. 4
d. 5

b. 3

Explanation:

Each level has its electrons distributed in different sub-levels, which can be of four types: s, p, d, f

In each sub-level, there is a certain number of orbitals that can contain a maximum of 2 electrons each.

For example, the sub-level s can only contain 2 electrons, therefore it has only one orbital.

The sub-level p can contain 6 electrons, and since each orbital can contain a maximum of 2 electrons it means that the sub-level p has 3 orbitals.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
