What do the observations for changes to volume and pressure show you about the relationship between the volume and pressure of a gas? Explain using the data! Does this demonstration support Boyle's Law or not?

(Hint: pressure is not being measured in this video, but think what would happen to a balloon if it was squeezed or compressed. Would it get larger or smaller?)

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.

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.
