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
Answer:
4,084
Step-by-step explanation:
Volume of a cylinder formula 
h = 13ft
r = 10ft (20/2)
Then you solve
Answer: 6 minutes.
Step-by-step explanation: You can use a graphing calculator to see the exact graph, but you're trying to figure out what value of x gives you a y of 0. -50 times 6 is 300, plus 300 equals 0.
Answer:
w = 3
Step-by-step explanation:
-6(w - 4) + 8W=6(w + 2)
-6w + 24 + 8w = 6w + 12
2w + 24 = 6w + 12
12 = 4w
3 = w
Answer:
-2
Step-by-step explanation:
To answer this, just take the negative reciprocal of 1/2. We obtain -2.
