The concentration of hydrogen peroxide in an antiseptic solution was determined by titration with 0.0200 M potassium permanganate solution. 20.00 mL of the peroxide
solution were acidified and titrated with the potassium permanganate solution. An
average titre of 18.93 mL was required. The concentration of the hydrogen peroxide in
the solution was ...

2 mole MnO2 : 5 mole H202
A) 0.2366 M
B) 0.5915 M
C) 0.04733 M
D) 0.1183 M

City a and city b had two different temperatures on a particular day. on that day, four times the temperature of city a was 8â° c more than 3 times the temperature of city b. the temperature of city a minus twice the temperature of city b was â’3â° c. what was the temperature of city a and city b on that day? city a was 5â° c, and city b was 4â° c. city a was 3â° c, and city b was â’1â° c. city a was 8â° c, and city b was â’3â° c. city a was 5â° c, and city b was â’5â° c.

What reaction is taking place? 02 + c3h8 = h20 + co2
