A student tested a sample of carbon (C) by combining it with water. There was no reaction between the carbon and water. The student concluded that carbon must be a
group 18 element, since it was unreactive is this conclusion correct? Why or why not?
(2 points)
O Yes Water would react with almost every element, except Group 18 elements
No. The carbon probably did react, but did not give off any signs or indications of a chemical
change
No. Just because carbon did not react with water, does not mean it wouldn't react with a
different compound
Yes. The student can make a reasonable conclusion based on one experiment.
