Answer:
The correct answer is (b)
Explanation:
Charles law describes the behavior of gases when heated. Charles law states that the volume of a given mass of gas would increase as its Kelvin temperature increases provided the pressure is held constant. That is the volume of a given mass of gas is directly proportional to its Kelvin temperature at constant pressure
The correct answer is option B. Dirty water is a mixture of solid particles and liquid. It is both a mixture and pure substance.
The dirty water sample has both gravel and liquid water in it. After filtration the gravel is removed so the water sample looks clearer than before filtration. Liquid water is a pure substance because it is a compound that is made up of elements hydrogen and oxygen. Now the gravel is only physically combined with the liquid water, thus giving the water sample properties of a mixture. And like any mixture, gravel is physically separated through filtration from the liquid water.
Thus the water sample of the chemists is both a mixture and pure substance.
Answer:
D.
Explanation:
The action of clearing a wide area of trees.
Yes. The model represents atoms rearranging to produce a new compound.
<h3>What chemical reactions?</h3>
They are reactions involving the breakage of bonds and rearrangement of atoms in reactants to form products.
In the model, the bonds between hydrogen and chlorine were broken. Thereafter, each hydrogen and chlorine molecule linked up to form hydrogen chloride.
Thus, the model shows atoms rearranging to produce a new compound.
