Some more examples of chemical changes are: Souring of milk ; Formation of curd from milk; Cooking of food (like rice and chapatis); Spoilage of food ; Change in colour of cut apple (cut brinjal or cut potato) on keeping in air ; Photosynthesis ; Digestion of food ; Neutralisation reac...

If ice melts in a glass of iced tea, and the colour of the liquid changes due to that, is that a physical or chemical change and why? What is an endothermic phase change? Is dissolving a solid in water a chemical reaction? Is sublimation endothermic or exothermic?
Colour change in these polyphagous larvae is a continuous reaction norm in response to colour cues from the twigs in the larvae’s immediate surroundings rather than the leaves they eat20. The precision of this colour and pattern response is at odds with the simple larval ocelli21, and the ...
These examples suggest that corals may retain phenotypic plastic- ity in their adult life stage, which can itself be a trait affected by the corals' environment52. In tandem with high levels of intragen- erational plasticity, multigenerational exposure of corals to altered environmental conditions ...

My thanks to reader amethyst for reporting a typo on page 487 of PiHKAL, in the entry for #11 BEATRICE: the product of the reaction would be N-cyclopropylmethyl-2,5-dimethoxy-4-methylamphetamine rather than N-cyclopropyl-2,5-dimethoxy-4-methylamphetamine as stated. 2014-02-28 Roughly 90 ...
aUsually, completion of the reaction is indicated by a sudden, visible change in the reaction system that coincides with the stoichimetric relationship between moles or equivalents of the regent solution and the reactant in the test solution. A drop or two of an appropriate indicator solution ...
