The chemical equation for the combustion of hydrogen is shown below. A scientist burns 6 g of H2 in excess oxygen
and collects 40 g of water. What is the percentage yield of
the reaction?
2H*2 + O*2 2H*2*0

Iwll give extra points to who gets this for ! what type of reaction is this? ?

In the millikan oil drop experiment they determined that every drop had a charge which was a while number multiple of -1.60x10^-19. if a drop has a total charge of -9.60x10^-19 then how many excess electrons are contained within the drop?

What are the first three quantum numbers for the electrons located in subshell 2s?
