We pull up stakes also test starch amounts with kinsperson foods and observe the chemical changes. In addition to the foods, we are to handle some kinsperson chemicals (which will be listed) and test them with some of the samples that we have in the Observation of Chemical Changes lab kit. info Table 1: Reactions Expected |Well #/Question |Chemicals |Reaction | |A |NaHCO3 and HCI - C0 2 |A1: W: No color change.
