If a closed "piston-container" of water and CO2 gas were warmed, and the volume were expanded, what would be the expected change in solubility of the gas?
How do you know when to draw a single/double/triple bond when drawing Lewis Structures? I need a good answer because I still don't understand Lewis Strucctures.
The flask was then shaken until the solution was uniform. A 40.0-mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100 mL. of the final solution?
