Hi, guys so basically me and my friend are stuck on this science homework. The homework is basically determining if an experiment is a physical or chemical change. The experiment that we chose is "sugar water" (dissolving sugar in water). So we know that this is a physical change (that's not the hard part ), the hard part is evidencing and reasoning for our choice. thank you, and best regards, stevemango (test question #4)

Sugar dissolution in water is a physical change and not a chemical change because, when sugar is mixed in water, the water molecules break down the sugar molecules so, as a result sugar changes it's shape and gets dissolved in the water attaching the chain bonding between them.

Explanation:

That is a physical change

Explanation:A chemical change produces new chemical products. something new would need to result For it to be a chemicl change. If you evaporate the water from a sugar-water solution, you're left with sugar.

answer: they produce more slow than unicellular organisms.
