Yes.
Exothermic reaction.
Yes, if it occurs as the result of a chemical reaction. For example, if two clear colorless solutions form a white precipitate (solid) when mixed, that would be an example of a chemical change. The formation of a solid from freezing is a physical change.
When copper sulfate is heated the observation is that it turns white as the water which is driven off by the heat. It is also stated that the white solid will remain and if water is added to the anhydrous copper sulfate a reaction will occur.
it turns into a redish/orange type liquid. i think its because the white colour of the baking soda making the iodine lighter is making a type of chemical reaction.
white :)

Protein becomes denatured at high temps- ie:egg turns to a solid white from clear
The solution becomes cloudy due to the formation of calcium carbonate, a white solid.

the reaction between 2Al(s) +6HCL(aq) >>>> 2AlCl3( insoluble chloride) and 3H2(g) also a solid precipitate is formed by the bubbling of carbon dioxide into lime water
Frying an egg is a chemical change. The egg white turns white and solid as it is denatured, which cannot be reversed by physical means.
If you fry an egg it turns white and goes solid is it a chemical reaction? well no it isn't a chemical reaction cos it can not be reversed back to what it was in the first place. it can also be known as physical reaction xx hope that helped xx happy to help xx
It has a chemical reaction and the antacid starts to dissolve. or When you do the white vinegar with the antacid tablets together the tube/bottle explodes and causes a chemical reaction.
Potassium bromide (KBr) is a white solid formed by the reaction of potassium hydroxide and bromine.
When zinc sulphate and lithium react together, they form lithium sulphate and zinc as products. Zinc is a grayish-white metal, while lithium sulphate is a white solid. Therefore, after the reaction, you would observe a greyish-white solid and a white solid.
Phenolsulfonate is a colorless to white crystalline solid which turns pink on exposure to air.
