3. Color is a chemical property of a pure substance. From your observations of the color changes in the permanganate oxidation of benzaldehyde, make some deductions about the number of chemical species involved and if the organic compounds or the inorganic compounds are responsible for the colors observed.

See explanation

Explanation:

We know that in the presence of strong oxidizing agents such as permanganate , aldehydes are oxidized. This oxidation is often accompanied by a colour change.

The colour change in the permanganate oxidation of benzaldehyde is caused by the inorganic permangate. The colour changes from purple to colourless because Mn^7+ is reduced to Mn^2+.

The benzaldehyde is readily oxidized to benzoic acid in the presence of permanganate.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
