Answer:
700 mL of water
Explanation:
This is the perfect example of dilation calculations. Along with this concept we have a formula c = n ( solute ) / V ( solution ). Let us first solve for n by changing this equation to isolate the solute,
n ( KCL ) = 2.4 mol / L * 500 * 10 ^ - 3 L,
n ( KCL ) = 1.2 moles ( KCL )
Knowing the amount of moles of potassium chloride, we have to now identify how much is present in the target solution,
V = 1 .2 moles / ( 1.0 moles / L )
V = 1.2 L = 1200 mL
_______________________________________________________
Vadded = 1200 - 500 = 700 mL

I'll give you three just in case a couple are ones you aren't quite looking for.
-Carbon has several allotropes, or different forms in which it can exist. A couple of allotropes included are graphite and diamond, which both have very different properties.
-Despite carbon's ability to make 4 bonds and its presence in many compounds, it is highly nonreactive under normal conditions.
-Carbon exists in three main isotopes: ¹²C, ¹³C, and ¹⁴C in which ¹⁴C is radioactive and used in dating carbon-containing samples (known as radiometric dating)
Hope this helps!!
Ummmmmmm......... im in 6th grade and i do not understand 1 bit of this, but i tried, sorry! :)
Answer:
OPTION C) All hydrogen ions and all hydroxide ions have reacted to produce water, and so neither ion remains free in solution.
Explanation:
The PH reading on the left axis of the graph shows a value of 7.
A value of 7 on the PH scale implies that equal number of hydrogen ions completely reacted with hydroxyl ions to produce water i.e there is no excess of hydrogen and hydroxyl ion remaining in solution.
For values greater than 7, a basic solution is formed and it signifies the presence of excess hydroxyl ion. If the value is less than 7, there is more hydrogen ions in the solution formed and it is said to be acidic.
At point 7, the hydrogen and hydroxyl ions are equal and completely neutralize out one another.
Note: The acid solution would require a base volume of 20mL to be completely neutralized according to the plot. If it is less, the PH shifts to the left and the solution becomes acidic. If it more, the solution becomes basic and the PH shifts rightwards.
