Explanation / Answer
Using electricity to break apart a compound is called C. Electrolysis.
In electroplating, the C. Anode loses mass.
A sample of Argon gas has a volume of 735mL at a pressure of 1.20 atm and temperature of 300K. What is the pressure of the gas if its volume and temperature is changed to 900mL and 200K?
Answer is C. 0.653
P1V1 / T1 = P2V2 / T2
1.2 * 735 / 300 = P2 * 900 / 200
P2 = 0.653 atm
500mL of a gas at 25.0oC will have a volume of 1.20L at:
Answer is A. 4420C
V1 / T1 = V2 / T2
0.5L / 298K = 1.2 L / T2
T2 = 715.2 K - 273 = 4420C
When solid aluminum is placed in an aqueous solution of copper ions:
Answer is A. the aluminum will be oxidized and the Cu2+ reduced
