suppose you peform experiment 4.1 with a testtube that had a crack in it. gas could slowly leak out of the crack but not merely as quickly as it is being made in the experiment. suppose further that the crack was in the test tube that held hydrogen gas. which chemical formula might result from such a botched experiment/ HO or H4O?
HO because if the test tube had a leak there would be less hydrogen in the tube so we pick the formula that has the least hydrogen which is HO
