What is the concentration of H+ ions at a pH = 2? mol/L
In Step 5, you will calculate HOH ratios for more
extreme pH solutions. Find the concentration of H+ ions
to OH-ions listed in Table B of your Student Guide for a
solution at a pH = 2. Then divide the Ht concentration by
the OH concentration. Record these concentrations and
ratio in Table C.
What is the concentration of OH-ions at a pH = 2?

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
