There is a textbook question thats asks whether the bond angle between two hybrid orbitals to increase or decrease as the s-character of the hybrids is increased? what is s-character?

When it says as you increase in energy levels, the energy increases. Does that mean energy of the electrons or of the whole atom?

This is probably a weird question to ask but Lavelle mentioned in class the concept of rainbows and how its the sunlight passing through the water droplets in the air that act like prisms to deflect light as a rainbow. But I was wondering why don't we see forms of rainbows more often like when we ca...

Could someone please explain molarity and what it means because for different problems in the book it explains it in different contexts like transferring a distinct molarity of something into a particular beaker? Just the wording of some of the problems is confusing.

I was confused with the differences of when to use the Avogadro's constant as I thought it was used to find atoms per mole, but in other cases it's used to find molecules per mole. Could someone please maybe explain the difference between or shed some light on what the constant really means?

Hi, I'm having trouble understanding the fundamental problem M11). It reads "A reaction vessel contains 5.77 g of white phosphorus and 5.77 g of oxygen. The first reaction to take place is the formation of phosphorus(III) oxide, P4O6: P4(s) 1 3 O2(g) S P4O6(s). If enough oxygen is present, the ...
