Be sure to answer all parts. Ammonia is a principal nitrogen fertilizer. It is prepared by the reaction between hydrogen and nitrogen. 3H2(g) + N2(g) → 2NH3(g) In a particular reaction, 4.00 moles of NH3 were produced. How many moles of H2 and how many moles of N2 were reacted to produce this amount of NH3?

moles of H2

Mole ratio of H2 to NH3 is 3: 2

if 3: 2

? 4

= 4*3/2= 6

6moles of H2

moles of N2

mole ratio of N2 to NH3 is 1: 2

if 1 : 2

? 4

4*1/2 = 2

2 moles of N2

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.
