In this simulation, you will be exploring the relationship between temperature and pressure while keeping volume
constant. Click here to begin. Select the Explore box. Answer the questions as you perform the steps.
1. Raise and push down the pressure pump handle to add gas molecules to the container. The initial temperature is
300 K (27º) and the pressure has a range of 5.4-6.2 atm. Notice the pressure values change as the particles
collide with the wall.
2. Click on the bucket to raise the temperature of the container to approximately 400 K (127°C). What happened to
the pressure?
Approximately what pressure range did you observe?
3. Click on the bucket to reduce the temperature to approximately 200 K (-73°C). What happened to the pressure?
Approximately what pressure did you observe?
4. What gas law mathematically shows the relationships between temperature and pressure?

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

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?
