You place air in a sealed can at standard temperature and pressure (STP). You double its absolute temperature (K) while leaving the volume constant.
What happens to the pressure?

It doubles.
It decreases by one-half.
It increases to four times the original pressure.
It stays the same.

Agas has a volume of 0.7 l at 300 mmhg. what would be the new volume at 900 mmhg

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?

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?
