Help with science experiment: proving the law of conservation of mass?
Ok well for my homework in science class I am supposed to design an experiment that proves the law of conservation with these materials: triple beam balance; NaHCO3; vinegar; Erlenmeyer flask; balloon, water, scooplula, graduated cylinder.
The problem is, I don't know how to make an experiment with those materials lol... If anyone could help me out a little bit here and show me how to make an experiment with these materials or even just help me a little it would be greatly appreciated.
