Answer:
When it seemed a truly dark sky at night is one of the most magical experiences one can have.
Explanation:
an opinion is what someone thinks is true but someone else might thing a different way. In this case, the speaker thinks tha a truly dark sky at night is one of the most magical experiances someone can have. someone else might contradict this opinion by saying that its not a magical experiance. The first sentance isn't an opinion because it states that light pollution is an overuse of artificial light and it can cause bad consequences. this is a fact because it's true. The last sentance is a fact because it states something that is happening in the world as well.
I hope this helps you!
Given the reaction equation; ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l), the cell notation is Cu/Cu2+//ClO3-/Cl/Pt.
<h3>What is an electrochemical cell?</h3>
A electrochemical cell is one in which electrical energy is produced by chemical processess. In this case, the cell reaction equation is; ClO3−(aq)+3Cu(s)+6H+(aq)→Cl−(aq)+3Cu2+(aq)+3H2O(l).The electrode used here is Pt.
Looking at the equation, we can write the notation for the cell reaction as;Cu/Cu2+//ClO3-/Cl/Pt.

Inequalities are used to represent unequal expressions.
The solution set to
is: 
The inequality is given as:

From the inequality above, we have the following observation.
- The value of variable x starts from 7/16 (inclusive)
- The value of variable x has no end (i.e. infinity)
Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [
We treat
, as an exclusive value. So, we make use of the close parenthesis i.e. )
Hence, the solution set is:
