How can a half test tube of sugar and a half test tube of water add up to one full test tube?
When sugar dissolves in water, it occupies space within the water molecules, leading to an increase in volume. So, if you dissolve a half test tube of sugar into a half test tube of water, the volume of the mixture will be greater than the sum of the individual volumes of sugar and water, resulting in a full test tube.
Why did you test the hydrogen peroxide and sand in tube 4?
Tube 4 was used to test the reaction between hydrogen peroxide and sand to determine if any fizzing or bubbling occurred, indicating a possible chemical reaction. This test was performed to investigate the reactivity of hydrogen peroxide with sand and to observe any changes or reactions that may have occurred.

Mix clay and sand in a test tube what will happen?
Mixing clay and sand in a test tube will result in a heterogeneous mixture, as the clay particles will not dissolve in the sand. The two components can be physically separated by techniques such as filtration or sedimentation.
