(AKS 6a) A chemist performs an experiment according to the following chemical
reaction
2M 0,2MgO +861 K)
The chemist believes the graph to the right accurately represents the reaction. Construct an argument
as to why or why not the graph could represent this chemical reaction. (DOK 2)
Reaction Progress

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.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
