In an experiment, a student measured the maximum mass of sugar in grams that can dissolve in 100 mL of water at five different temperatures. (You will answer the questions below using this experiment and graph. Hint: Use Units) I'm not really understanding, so any type of tips would really help. Thank you!

Given sno2 + 2h2 - sn + 2h20 tin oxide reacts with hydrogen to produce tin and water. how many moles of sno2 are needed to produce 500.0 grams of sn?

Which of the following electromagnetic waves can create ions?

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?
