Balance the following redox equations. All occur in acid solution. (Type your answer using the format CO2 for CO2 and [NH4] for NH4 . Use the lowest possible coefficients.) (a) MnO4-(aq) (aq) HSO3-(aq) Mn2 (aq) (l) SO42-(aq)

Explanation:

Hello!

In this case, according to the given problem, we need to balance the following redox chemical equation in acidic solution:

Thus, the first step is to assign the oxidation states for both manganese and sulfur as that of oxygen is not changing from 2-:

Now, we realize that manganese is undergoing reduction from 7+ to 2+ and sulfur is undergoing oxidation from 4+ to 6+, so we write the half-reactions:

Next we insert the transferred electrons and the necessary hydrogen ions and water molecules to balance the half-reactions:

Then, we cross multiply the transferred electrons:

And we can add them up in the form of the initial reaction, by making sure we cancel out the transferred electrons at both sides and simply the common hydrogen ions and water molecules at both sides also:

Finally, the result is:

Best regards!

fire could start, buildings collapsing, and ash falling from the sky.

explanation:

this is because the buildings or plants could catch on fire and the buildings would most likely collapse. lastly ash would fall because all the burning would cause ash to fall from the sky.

hope this .
