In part D of task 1, you identified at least two ways in which the reaction of nitrogen and hydrogen could be changed to alter the equilibrium. Use the simulation to test those changes. Describe how you used the simulation to model the changes and the results they produced. Use these methods if you find them helpful: Look at the pie graph to see how the system changes. Use the Temperature slider at the bottom to cool or heat the mixture. Click the pause button on the simulation to observe the number of particles at any point of time.

the role of the microscope world in creating new materials .

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
