Given the reaction: P4 + 5 O2
2 P205

What is the mole ratio between P4 and O2? What about between P4 and P2O5?

How many grams of P4 would be needed to fully react with 2.5 moles of O2?

You need to create 82.2g of P2O5. What mass (grams) of P4 would be required?

Please show work.

Can someone me with questions 15 to 17 plz.

Which fact represents evidence for the big bang theory?

What are the first two quantum numbers for the electrons located in subshell 4d? what are the first three quantum numbers for the electrons located in subshell 2s? how many electrons can be held in a sublevel l = 3? how many electrons can be held in the energy level n = 4? how many electrons in an atom can share the quantum numbers n = 4 and l = 3?
