You have been given 0.5 grams of Cuso, and the balanced chemical equation above. Using this
information, complete the following calculations:
a) Find moles of Cu(SO) (n=m/M)

b) Use the mole ratio to find moles of Cu

c) Find mass of Cu
(m = nx M)

At stp, what is the volume of 1 mole of co2?

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?

An atomic nucleus is composed ofa)protons. b)protons and neutrons. c)protons and electrons. d)protons, neutrons, and electrons.
