Explanation:
How does it relate to a chemical reaction: Chemical energy is converted to kinetic energy when a stick of dynamite explodes.
Answer:
200cc of 5N HCl were diluted
Explanation:n
<em>Assuming the solution was diluted to prepare a 1N HCl solution:</em>
The HCl was diluted from 5N to 1N, that is a dilution of:
5N / 1N = 5 times
As the total volume of the diluted solution is 1L = 1000mL = 1000cc the amount of the concentrated solution was:
1000cc / 5 =
<h3>200cc of 5N HCl were diluted</h3>
