why bf3 behaves as a lewis acid? When one atom of boron combines with three atoms of fluorine, its octet remains incomplete. Hence, boron trifluoride remains electron-deficient and acts as a Lewis acid.
How do ice molecules behave? When water is in its solid state (ice), the water molecules are packed close together preventing it from changing shape. Ice has a very regular pattern with the molecules rigidly apart from one another connected by the hydrogen bonds that form a crystalline lattice.
How does ice behave in water? During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds. … Thus water expands as it freezes, and ice floats atop water.
How can ice be described? Ice is the solid state of water, a normally liquid substance that freezes to the solid state at temperatures of 0 °C (32 °F) or lower and expands to the gaseous state at temperatures of 100 °C (212 °F) or higher.

Is water small or large molecule?
For instance, water is a small molecule made up of two hydrogen atoms and one oxygen atom, so it is called H2O.

Single molecules can be made up of thousands and thousands of atoms.
