Which of the following sets of oxidation numbers is not correct? kmno4 : k +2, mn +6, o -2 nacho2 : na +1, c +2, h +1, o -2 zn(oh)2 : zn +2, o -2, h +1 scl2 : s +2, cl -1

KMnO4 has the incorrect set of oxidation numbers. Whenever there is an alkali metal, it has an oxidation number of +1. As you can see, K is said to have an oxidation number of +2, so it is incorrect.

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
