Plz answer asp the image shows the combustion of methane. which equation represents this chemical reaction?

a.
ch4 + o2 → co2 + h2o
b.
2ch4 + 2o2 → co2 + 2h2o
c.
ch4 + 2o2 → 2co2 + h2o
d.
ch4 + o2 → 2co2 + 2 h2o
e.
ch4 + 2o2 → co2 + 2h2o

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.
