1. tnt, (c7h5n3o6) reacts explosively with oxygen gas (o2) to produce co2 gas, water vapor, and n2 gas. if james weighs out 0.853 g of tnt, answer the following question: how many mg of o2 will react with the tnt?

631.3 milligrams of oxygen gas will react with the TNT.

Explanation:

Moles of TNT =

According to reaction , 4 moles of tNT react with 21 moles of oxygen gas.

Then 0.003758  moles of TNT will react with:

Mass of 0.01973 moles of oxygen ;

( 1 g = 1000 mg)

631.3 milligrams of oxygen gas will react with the TNT.

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.
