H+ ions increase in concentration at lower pH values. What is the concentration of H+ ions at a pH = 2?
Calculate how many more H+ ions there are in a solution
mol/L
at a pH = 2 than in a solution at a pH = 6. Find the
What is the concentration of H+ ions at a pH = 6?
concentration of Hions at a pH = 2 and at a pH = 6 in
Table B. Then divide the concentration of H+ ions at a
mol/L
pH = 2 by the of H+ ions at a pH = 6. Record your answer How many more H+ ions are there in a solution at a
in Table C.
pH = 2 than in a solution at a pH = 6?

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
