Suppose you mix Na2SO4 and KCl solutions according to the given equation. Na2SO4 (aq) + 2 KCl(aq) + 2 NaCl(aq) + K2SO4 (aq)
What evidence of a reaction do you expect to see?
Select one:
A precipitate should form.
A gas should form.
Water should form.
Ο Ο
No reaction should occur.

No reaction should occur

Explanation:

Water cannnot be made from the components

Nothing will be released as a gas

Both products are soluible in water therefore will not form a precipitate.

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.
