Answer:
Pb(s) ---> Pb+2 + 2e- is the anode
Cu+2(aq) + 2e- ---> Cu(s) is the cathode
Answer:
2 M
Explanation:
mole weight of CaBr2 = 40 + 2 * 79.9 = 199.8 gm
20 gm is then 20/199.8 =.1 mole
.1 mole / .50 liter = 2 M
This is how you convert gallons to liters.
- Gallon is a volumetric unit.
- 1 gallon equals 3.785 liters
- So, you create this conversion factor: 1 gal = 3.785 liter ⇒ 1 = 3.785 liter / 1 gallon.
- Therefore, you can multiply any amount in gallons by the conversion factor and get the equivalent amoun in liters.
- Examples:
- 1 gallon = 1 gallon × 3.785 liter / gallon = 3.785 liter
- 3 gallon = 3 gallon × 3.785 liter / gallon = 11.355 liter
- 15.25 gallon = 14.25 gallon × 3.785 liter / gallon = 53.936 liter
Entropy is a measure of chaos or disorder in a system. For the first one, the system with the highest entropy is a cup of water at 0 degress centigrade. For the second question, the system with the lowest entropy is sugar crystals in 95 degrees centigrade cup of coffee.
