The balanced equation that shows the reaction between oxalic acid and permanganate ion in an acidic medium is: 2MnO4- + 5H2C2O4 + 6H+ -> 2Mn(2+) + 10CO2 + 8H2O. Thus, 1 mole of oxalic acid reacts with 0.4 mole of permanganate ion. This was obtained using stoichiometry:

1 mol H2C2O4 x (2 mol MnO4-/ 5 mol H2C2O4) = 0.4 mol MnO4- 

In this redox reaction, the permanganate is reduced to manganese(II) ion.

Is this the correct procedure for cleaning volumetric glassware prior to making a measurement: first, rinse with tap water. Seco
Bogdan [553]

The steps to be followed while cleaning volumetric glassware are:

1. Remnants from the previous measurements are wiped off with the help of paper towel.

2. The glassware is then soaked overnight in warm soap solution.

3. Then before rinsing with tap water, the glassware are scrubbed with an appropriate brush.

4. After scrubbing, the glassware is rinsed thoroughly with tap water in order to make sure there are no traces of soap solution.

5. The glassware is then rinsed with de-ionized water and finally with the solution that would be used for the volumetric measurement.

In Europe, gasoline efficiency is measured in km/L. If your car’s gas mileage is 25.0 mi/gal, how many liters of gasoline would
Deffense [45]

Answer:

V=23.5L

Explanation:

Hello,

In this case, it is convenient to compute the car's mileage in km/L as follows:

25.0\frac{mi}{gal}*\frac{1km}{0.6214mi}*\frac{1gal}{3.78L}=10.64\frac{km}{L}

In such a way, since the distance is measured to be 250 km, the volume requirement is:

V=\frac{250km}{10.64kg/L}\\ \\V=23.5L

Regards.
