URGENT Iron reacts with oxygen at high temperatures to form iron(III) oxide.

4Fe(s)+3O2(g)⟶2Fe2O3(s)

Suppose 19.6 g of iron (Fe) is reacted with 19.6 g of oxygen (O2).

1.) Calculate the theoretical yield of iron(III) oxide ( Fe2O3 ).
2.) The reaction produces 6.47 g of Fe2O3. What is the percent yield of the reaction?

yes

explanation:

search chemistry final b exam in google and a site called quizlet will pop up

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.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
