The balanced chemical reaction is:
<span>Ca(OH)2 + 2 HCl = 2 H2 O + CaCl2
</span>
We are given the amount of hydrochloric acid to be used in the reaction. This will be the starting point for the calculations.
0.124 mol HCl / L soln ( .0375 L solution) ( 1 mol Ca(OH)2 / 2 mol HCl) / 0.020 L Ca(OH)2 solution = 0.12 mol / L Ca(OH)2 = 0.12 M
The rest station is the midpoint of the given coordinates:
(-20+35)/2 , for the x value and (15+-12)/2 for the y value.
Coordinates of the rest station: (7.5, 1.5)
How far is the destination? Use the distance formula : D² = √(x1-x2) + (y1-y2)
(-55)² + (27)² = D² D = √3754 = 61.27
