HELP ASAP REAL ANSWERS ONLY 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.

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
