Don’t understand

Concept: Chemical Analysis

You need to start by graphing the data and then analyzing it.We can see that the horse has a distance in meters of 980 at the end of the 10 seconds hence it is the fastest.The horse line has a linearly representation, while the alternate line has parabolic tendencies towards the end. The steeper line indicates a faster change in time or velocity which results in a greater distance traveled indicating that the horse is faster.*I have confidence you can graph that*

(no3)⁻n has oxidation number x,o has oxidation number -2.(x*1 -2*3) charge of the nitrate ion, and we know that charge of the nitrate ion =-1.so,(x*1 -2*3) =-1x-6=-1x=+5answer a. +5.
