Nitrogen and hydrogen react together to form ammonia according to the equation: (g) + (g) → (g) (unbalanced)balance the equation, and determine how many grams of hydrogen would be required to form 50.0 g of ammonia, assuming there is sufficient nitrogen available.4.46 g5.94 g4.81 g8.91 gnot enough information

Explanation:

To balance the equation:

1) Asume 1 mol of N2 :

2) Balance the nitrogen:

3) Balance the hydrogen:

To calculate the hydrogen:

Due to the equation you need 3 mol of hydrogen per 2 mol of ammonia:

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.
