A chemical reaction occurs when 2 white solids are stirred together. They turn into a slushy, white solid and the glass jar feels really cold. Energy is being by the solids, which means this is an reaction.

A) Released, exothermic
B) Absorbed, endothermic
C) Released, endothermic
D) Absorbed, exothermic

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. 

B. elliptical. as in oval. 0 (==
