Question 1 ( points)
how many orbitals are presentin pubshell

p - subshell contains three orbitals 2px, 2py and 2pz.

Explanation:

Each p - subshell consists of two section better known as lobes which lie on either side of the plane passing through the nucleus. The three p-orbitals differ in the way the lobes are oriented whereas they are identical in terms of size, shape and energy. As the lobes lie along one of the x, y and z axis, these three orbitals are given the designations 2px, 2py and 2pz. Thus, we can say that there are three p - subshells whose axes are mutually perpendicular.

distance, luminosity, brightness, radius, chemical composition, and temperature

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 :
