How do limiting reactants work vs excess reactants?
Limiting reactants restrict the amount of products that can be formed and excess reactants does not restrict/ limit the amount of products that can be formed.
What is the difference between non-polar covalent bonds and polar covalent bonds?
Non-polar is when 2 atoms of the same element from CB and polar is when 2 atoms of different elements form CB
What is the difference between density and conductivity?
Density is the amount of Mass for volume of substance and conductivity is the measure of the measure of electricity.
