Answer:
Total charge= -25
Step-by-step explanation:
Given :
Charges of some ions
Aluminium +3
Phosphate -3
Chloride -1
Silver +1
To find total charge on 8 phosphate,7 chloride and 2 Aluminium atoms
Aluminium +3 × 2 =+6
Phosphate -3 × 8 = -24
Chloride -1 × 7 = -7
total charge=
+6-24-7 =+6 -31
= -25
Since you don't show the graph, all I can do is to tell you how to identify which function is parallel to the x-5y=8.
First let's rearrange the function.
x-5y=8
5y=x-8
y=1/5x-8/5.
Thus, it gives us the slope of the function, which is 1/5.
And the function that is parallel to the graph would have the SAME slope. Which is 1/5. So all you need to do is to find which function has the SAME SLOPE, in this case: 1/5.
The Venn diagram shows that rational numbers include all integers (-3, -2, -1, 0, 1, 2, 3,) and all whole numbers (0, 1, 2, 3, 4, 5). Inside the <u>rational </u><u>numbers</u> circle is the <u>integer circle</u>, and the <u>whole numbers </u>circle, which concludes that all integers and whole numbers are rational numbers.
