So we did an experiement to test unknown gases that are produced when hyrdogen peroxide and manganese dioxide react, when HCl and magnesium react and when HCl and sodium bicarbonate react.
would the relevant control variables be like the amount of acid used...and things like that? im not sure ahh.
please help and explainn=) thank youuu so much!What are the relevant controlled variables in this experiment?
Controlled variables are anything that was the same between the two experiments. So the amount of acid used, time, or anything else that stayed the same between the two.What are the relevant controlled variables in this experiment?
Yes the Control are the things you always keep the same
Such as:
The amount of water/acid whatsoever
The same test tubes?
Same Time they were put in something like that* Think of all the things that related to each other
