Why (if you are careful) are you able to float a needle on the surface of water? Select one: O Water has adhesive properties Don't use Ai for answering this O The surface tension that is a result of water's cohesive properties makes this possible The covalent bonds that hold a water molecule together make this possible A single needle is less dense than water

(b) Explain what hydrogels are as a group of material. Discuss and illustrate with examples the most important properties of hydrogels.
ge Bonds formed by equal sharing of a pair of covalent electrons are called bonds because there is a uniform charge across the molecule along all axes. Attractions between polarized molecules (intermolecular bonds and can also bonding) are called form between polarized regions of the same molecule (intramolecular bonding).
