Draw a physical model that shows the reaction of in metal and hydrochloric acid (hydrogen chloride) Zinc Hydrochloric Acid - Zinc Chloride and Hydrogen Gas
Zn. 2HCI - ZnCI2
Be sure to label your model to clearly show how you are representing the stoms, how they are rearranged and that mass is conserved in the
reaction

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
