Answer:
P is 5 ticks to the left of 0, so it would be -5/8
Q is 5 ticks to the right of 0, so it would be at 5/8
an absolute value turns a negative number into a positive number
so absolute value of P located at -5/8 = 5/8
this is the location of point Q
Jimmy said that the absolute values of the numbers represented by the two points are the same.
so Jimmy is correct

Answer:
Mg + 2H₂O —> Mg(OH)₂ + H₂
Explanation:
Mg + H₂O —> Mg(OH)₂ + H₂
The above equation can be balance as illustrated below:
Mg + H₂O —> Mg(OH)₂ + H₂
There are 2 atoms of H on the left side and a total of 4 atoms on the right side. It can be balance by writing 2 before H₂O as shown below:
Mg + 2H₂O —> Mg(OH)₂ + H₂
Now, the equation is balanced
