1)
Magnesium reacts with oxygen gas to form magnesium oxide
according to the reaction below:
2 Mg (s) + O2 (g)
⟶ 2
MgO (s)
How many grams of MgO will be produced from 4.79 L of oxygen at
STP?
2)
A solution is made by diluting 254 mL of a 2.27 M KCl stock
solution with water to a final volume of 1.16 L. What is the molar
concentration of the diluted solution?
3)
2 LiOH (aq) +
H2SO4 (aq) ⟶ 2 H2O
(l) + Li2SO4 (aq)
How many mL of a 0.286 M lithium hydroxide solution will be
required to completely react with 64.7 mL of 1.3 M sulfuric acid
solution?
4)
What is the pOH of a 0.02 M solution of HCl?
5)
125 mL of a Ca(OH)2 solution is neutralized by
33.6 mL of 1.50 M HCl. What the the molarity of the titrated
Ca(OH)2 solution?
Ca(OH)2 (aq) + 2 HCl ⟶ 2
H2O (l) + CaCl2 (aq)
