As shown in the following diagram, 10 mL samples of HBr(aq) are added to different quantities of E(s) in a closed test tube. At the start of each trial, the gas-collecting tube is filled completely with distilled water. The samples of E(s) react with HBr(aq) , and the H2(g) produced is collected in the gas-collecting tube.
The enlarged view of the gas-collecting tube at the end of trial 3 is shown in the diagram.
What should the student record as the volume, in mL , of H2(g) collected in trial 3?
