Convert/Calculate the following:
Determine the identity of an elemental gas if 4.55 L weighing 35.4g, under 5.0 atm is at 40oC
What is the pH scale? What is the range? What is an acidic solution? What is a basic solution? How is pH calculated? If the pH is 3.8, what is the pOH? What would be the [H+]?
A) Describe the process for preparing 400 mL of a 2.0 M NaOH solution from a 10.0 M bottle of NaOH. B) How would you make it from solid NaOH? C) Describe how to prepare 300g of a 5% NaCl solution.
Calculate the molarity of HCl if 18.5 mL of 2.8 M NaOH reached the end point when titrated with 5.0 mL of HCl. The reaction is HCl + NaOH à NaCl + H2O
