Question

2. The experimental and theoretical volumes should be the same. Complete the following sentences, explaining the sources of error. a. If there is an air bubble in the top of the test tube, the volume of experimental theoretical hydrogen would be affected, and would it appear too The low/high volume would be experimental/theoretical too high/too low/unchanged b. If the copper anode was not dried, the change in mass would appear too low/high The volume of hydrogen would be affected, and would make it experimental theoretical appear too The volume would be low/high experimental theoretical too high/too low/unchanged c. If the copper anode and cathode were touching, the change in mass would appear too The volume of hydrogen would be affected, and would make it appear too The volume would be 292

Answer 1

a) of there is an air bubble in the top of the test tube, the experimental volume of hydrogen would be affected, and to ould it appear too low. The theoretical volume would be unchanged. b) of the copper anode was not dried, the change would appear too high experimental rolume of hydrogen would be affected, and would make it appear too low theoretical volume would unchanged. in mars The The be cathode were ere e) Y the coppen anode and touching, the change in mass would appear too low The experimental rolume of hydrogen would be affected, and would make it appear too high. The e theoretical volume would be unchanged ..
