This is a photograph of an open textbook, likely taken in Jalingo, Nigeria. The book displays an illustration of an experiment involving hydrogen combustion, labeled "Fig. 17.4 Hydrogen burns in air to produce water." The illustration shows a retort flask generating hydrogen gas, which is then passed through a jet and ignited. Collected water droplets are visible in an evaporating dish below the flame, and anhydrous copper(II) sulfate is shown turning blue, indicating the presence of water. The accompanying text describes the experimental procedure, cautions, results, and conclusions of this experiment. Below this, another section is visible with the heading "Fig. 17.5 Open lattice structure of ice," accompanied by an illustration of the molecular structure of ice. The surrounding environment is dark, suggesting the photo was taken in low light conditions, possibly indoors. There is no visible indication of the city of Jalingo, Nigeria, other than your prompt.
