A sample of gas occupies 50.0 L at 15.0 Celsius and 640.0 mmHg pressure. What is the volume at STP?
acid base equllibrium
What is the pH of a solution, given that it has a [OH]- = 4.3 x 10^-8. Describe whether you think this material is a strong acid, weak acid, neutral, weak base, or a strong base.
A solution containing water has a .[H3O]+ = 1.57 x 10^-13a.) What is the [OH]-b.) Justify whether the solution is acidic, basic, or neutral.
