No, mixing sugar and chocolate is not a chemical change. It's a physical change.
No. Mixing salt and sugar is a physical process.
Yes, because a chemical change would mean that salt or sugar would have to change in chemical formula or state of matter
no it is a mixture not a compound
Organic SolventsBenzene and other solvents will dissolve sugar, but not salt. Salt is slightly soluble in ethanol, but this method can be used for experiments. Add the mixture to ethanol and strain out the salt with filter paper. Evaporating the ethanol will leave the sugar behind.Water Solution First in a large glass of cold water and mix the "Salt+Sugar" you have there.Then wait until some solid particles form on the bottom of the glass.Carefully take the water out of the glass.The solid particles are SUGARThen the water is SALT+WATERTake the "Salt+Water" and boil it until there is no more water.Then you will end with just SALT (hot salt...)In theory, if a water solution is cooled, sugar crystals should precipitate before the salt, but this is difficult to control experimentally.
To call it an physical or chemical change, we first need to describe both of them briefly. A physical change is the one which does not change the chemical properties of a substance. A chemical change is the one which changes the chemical properties of a substance. Whether they can be recovered or not is not of importance here. So if you mean to dissolve some powder in hot water such that it does not make any reaction with water, then its a physical change. (Mixing flour or salt or sugar powder are examples) However if you put some powder in hot water which creates a reaction and the molecules of that powder are no longer the same, then it would be a chemical change. (Adding tiny sodium or potassium pieces to water are examples)
yes.The chemical structure of salt(NaCl) is simpler than that of the sugar (C6H12O6)
salty plants..
sodium is a metal that is highly reactive with water while sugar is a sweetener you put in your tea. Sodium chloride which is sodium and chlorine makes table salt which is... well salty so your all in all answer in no
Among salt, sugar, water and lemonade, only lemonade is a mixture.
Sugar and Salt
Mixing salt and pepper is a physical change because no new substances are formed. The salt and pepper remain as separate entities even though they are combined.
Remove the sugar
That depends on what you are talking about. There will be no mixing of salt and sugar just as solids, but if they were in aqueous solution, you can force a chemical reaction.
Burning wood
Physical change as no new substance is formed and the properties have also not changed. Hope it helps!

Physical
Mixing salt and water is a physical change. This is because no new substances are formed during this process; the salt dissolves into individual ions in the water but can still be recovered by evaporating the water.
The dissolving of salt or sugar in water is a physical change because only the appearance of the substances is altered, not their chemical composition. The salt or sugar molecules remain the same; they are simply dispersed in the water at a molecular level.
