A solid white substance A is heated strongly in the absence of air. It decomposes to form a new white crystalline substance B and a gas C. The gas ignites readily when combined with hydrogen gas and a liquid uncolored substance resulted. Based on these observations, can we determine whether solids A and B and gas C, are elements or compounds?

A and B as well C are the compounds.

Explanation:

So that the above is the correct answer.

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.
