Which of the following correctly represents the decomposition of potassium chlorate to produce potassium chloride and oxygen gas? Which of the following correctly represents the decomposition of potassium chlorate to produce potassium chloride and oxygen gas?

2KClO3(s) + heat → 2KCl(s) + 3O2(g)

Explanation:

KClO3(s) + heat → KCl(s) + O2(g)

Adding coefficients so that there are 6 O atoms on both sides.

2KClO3(s) + heat → KCl(s) + 3O2(g)

Balancing K and Cl atoms, there are 2 of each on the left and 1 of each on the right.

2KClO3(s) + heat → 2KCl(s) + 3O2(g)

The equation is now balanced.

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.
