A chemist neutralizes 25.0 ml of a solution of H2SO4 with 25.0 mL of a 0.300 M solution of KOH. what is the molarity of the H2SO4 solution? Hint: start with a balanced chemical equation! 0.150 M 0.600 M None of these answers is correct

2. Answer the following questions about the reaction shown below. 3 H2O2(aq) + CH3OH(aq) -> 5H20(1) + CO2(g) a. Is this reaction classified as combustion, acid-base or redox? Justify your answer. b. What observation would you expect to see in the lab when this chemical reaction takes place? c. If 100 mL of 0.50 M H2O, and 100 mL of 0.50 M CH3OH are combined... What is the limiting reactant? and How many grams of CO, will be produced?

if 25 ml of water was added to 125 ml of a 0.15 m naoh solution, what will the molarity of the dilutied solution be?

What is the concentration of F— ions when 266.640 mg of MgF2 (62.3018 g/mol) completely dissociates in 2.442 L of water? Enter the numeric answer only in the units of mM (millimolar). Do not enter the unit.
