If 100 g of Mg reacts with excess HCl, what volume of hydrogen gas at 25 degrees C and 1.0 atm pressure will be produced. balanced equation
When an ant bites you, the reason it stings is because of an injection of formic acid. What is the pH when 50.0 mL of 0.1480 M formic acid (HCOOH) is titrated with 40.2 mL of 0.1841 M NaOH? PKa formic acid = 3.745.
The rate constant for a certain reaction is K = 8.90×10^-3 . If the initial reactant concentration was 0.950 M, what will the concentration be after 14.0 minutes.
A certain weak base has a Kb of 7.80 × 10-7. What concentration of this base will produce a pH of 10.16
190 mL of an HCl solution with pH of 3.60 is added to 200 mL of an HNO3 solution. The resulting pH is 1.40. What was the pH of the original HNO3 solution?
Decide whether or not the metal K dissolves in 1 M HCl. For this metal, if it does dissolve, write a balanced redox reaction showing what happens when the metal dissolves.
