What is the pH of a 1L buffer containing 1.5M Acetic Acid and 1.0M Sodium Acetate? What is the pH of the buffer when 0.5 moles of NaOH is added to solution? Assume no change in volume.
condensed form in order of increasing orbital energy as a string without blank space between orbitals.
Determine the molar mass of each of the following gases: a) 2.90 g of a gas that occupies 0.500 L at 0 degrees C and 1.00 atm (STP); b) 1.43 g of gas that occupies 2.00 L at 0 degrees C and 760 mmHg (STP); c) 0.726 g of a gas that occupies 855 mL ..
determine the molecular formula. Enter your formula as plain text, with carbon first, then hydrogen, the chlorine. So if the formula were C10H21Cl, you would enter C10H21Cl.
