Answer:
When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate.
Explanation:
. P.S. Evaporation to dryness cannot be use for solutions like sugar solution because the sugar will decompose upon heating.
The answer to this question would be: enzyme
<span>Enzyme is a kind of catalyst that </span>will take part in the chemical reaction but it won't be reacted. E<span>nzyme </span>only helps by reducing the energy needed to start the reaction.
Theoretically, the enzyme is not mandatory needed but if you have an enzyme the reaction will be easier, thus increasing reaction speed. But in most case, the reaction might be too slow without enzyme, making enzyme vital in living organism.
Answer
Do you think that the mole should be considered a base unit in the SI system?
The mole is not a base unit on a par with the six property base units; it cannot be used in significant physical–chemical comparisons until the subscript parameter p in mole-of-Ep has been given a certain “value”."
Explanation:
The answer would be c as the cart is not in motion therefor ruling out kinetic and it is completely at rest making all of it energy potential
Well. Depends.
You plan on doing a school project?
You should try baking soda and vinegar, almost everyone knows about this.
Orr you can use mentos and soda.
Or for fun, just get a watermelon or any fruit and use rubber bands all around it until it goes BOOM!
Hope this helps :D
