Week 4 Discussion: Chemistry in the World Around Us Initial Post Instructions While we often do not realize it, acidic and basic solutions are a part of our daily lives. Pick a solution in your home, work, or even outside (be sure to check the label to make sure that whatever you are measuring is nonhazardous and water based). Some possible solutions are shampoos, beverages, still water in your backyard, contact solution, etc. Research a compound or compounds found in your chosen solution, c...

Solve these ideal gas law problems. Show all work for credit. 1. A gas occupies 250 mL at 739 mmHg. For a gas at constant temperature, determine the volume of gas at 514 mmHg. (1.5 points) 2. Use the molar volume of a gas, at STP, to determine the number of moles of CO2 in 4.00 L of CO2 gas. (1.5 points) 3. A sample of nitrogen (N2) has a volume of 50.0 L at a pressure of 2 ATM. What is the volume of gas at a pressure of 15 atm, if there is no change in temperature? (1.5 points) 4. A 0.6 L...
