Analysis/conclusions: 1. balance the equation for the reaction between magnesium sulfate and ammonia. (2 points) + → )2so4 + (oh)2 2. classify the reaction between magnesium sulfate and ammonia. 3. what evidence was there to indicate that the epsom salts and ammonia reacted?

electron microscopy and scanning tunneling microscopes gives us a greater understanding of atoms by being able to see the atom itself, and lets us see some atomic reactions.

explanation:

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.
