3. What is the shape of 3p atomic orbital? (1 point)
sukhopar [10]

Option B

dumbbell is the shape of 3p atomic orbital

<u>Explanation:</u>

Atomic orbitals are three-dimensional places inside an atom where there is a tremendous chance of detecting electrons.  The p orbital, which develops in complexity and ought 2 spaces encompassing the atom core, or is defined as possessing a dumbbell pattern. The 3p atomic orbital is at energy level 3, as seen by the number 3 filed ere the character.

These orbitals have identical appearances but are arranged asymmetrically in location. p orbitals are wavefunctions with l=1. They ought an angular frequency that is ununiform at each angle. They have an appearance that is much defined as a "dumbbell".

A gas occupies 100.0 mL at a pressure of 780 mm ahh. What is the volume of the gas when it’s pressure is increased to 880 mm Hg
vlabodo [156]
Hello!

The volume of the gas when its pressure is increased to 880 mm Hg is 88,64 mL

This question can be easily answered using the Boyle's Law, which states that as pressure increases, the volume is lower. It can be expressed in a mathematical way as follows:

P_1*V_1=P_2*V_2

So, from this equation we can clear V₂ to find the volume at 880 mm Hg:

V_2= \frac{P_1*V_1}{P_2}= \frac{780 mmHg*100 mL}{880 mmHg}=88,64 mL

Have a nice day!
