### 2A + 1B ---> 3C

2A + 1B ---> 3C If one mole of A is mixed with one mole of B which is the limiting reactant? How much of B would be used? What is the maximum amount of product that can be produced? I'm having trouble understanding how A would end up being the limiting reactant if there are fewer moles of B. Could s...

### Module: Molarity and Dilution of a solution

5.00 g of KMnO4 is dissolved in a 150.00 mL flask of water. If 20.00 mL of this solution is removed and placed in a new 2nd 250.00 mL flask and filled with water, what is the concentration of the solution in the 2nd flask? Molar Masses: K (39.10 g/mol), Mn (54.94 g/mol), O (16.00 g/mol). I'm a bit c...

### E.15

The molar mass of the metal hydroxide M(OH)2 is 74.10 g.mol-1. What is the molar mass of the sulfide of this metal?
I don't see an S in M(OH)2 so I'm not exactly sure what sulfide they are talking about in this problem. Could someone walk me through it?

### Mass of AgCl produced?

According to the following equation, 0.750 g of C6H9Cl3 is mixed with 1.000 kg of AgNO3 in a flask of water. A white solid, AgCl, completely precipitates out. What is the mass of AgCl produced? C6H9Cl3 + 3AgNO3 ---> AgCl + C6H9(NO3)3. Molar Mass: C6H9Cl3 (187.50 g/mol), 3AgNO3 (169.88 g/mol), AgCl (...

### Reviewing High School Chem Tips

Hello, I was wondering if anyone knows of any good resources that they think would help with reviewing high school chem. I took honours chem in sophomore year of high school, so I'm pretty anxious, especially since it's been three years since I've done chemistry. Thanks!
