Out of the given options, “It has varying properties” is the correct one about the characteristic of a mixture.
Answer: Option C
<u>Explanation:
</u>
A mixture usually formed when more than one elements get mixed. In the process of forming a mixture, the constituent elements don’t drop their individual property and hence, the product shows mixed characteristics.
The prime characteristics of the mixture are that they show varying properties according to its constituent elements. All states of matter can combine to form a mixture such as air, ink, gunpowder, etc.
It’s generally easy to separate the elements of a mixture through physical processes. There is no variation of energy during the mixture formation and the proportion of the elements may vary.
Yes, entropy increases during sublimation. This is because, there is a change of phase from a solid state to a gaseous state which causes an increase in the disorderliness of the particles in the solid matter.
Mass of a model car you measured = 230 grams
Actual mass = 218 grams
Percent error = ?
First subtract the actual value from the value
you measured,
230 grams – 218 grams = 12 grams
Now divide 12 grams by the actual mass that is
218 grams:
12 / 218 = 0.055
Now multiply 0.055 with 100 to get the percent
error;
0.055 x 100 = 5.5%
So, the Percent error is 5.5%.
