air that is cooling will cause the highest pressure
Explanation:
This is because heat has to escape a certain area and if the heat can't escape then more and more pressure will build up in a area.
Answer:
equation 1: AgNo3 + Zn is the reaction because of the zinc
A.) <span>Each molecule of hydrochloric acid, HCl, contains one atom of hydrogen and "One atom of Chlorine"
Hope this helps!</span>
You need a control so you have something to compare the experimental group on-- If you don't have a control group, how will you know what's changed?
The acid dissociation constant is 1.3 × 10^-3.
<h3>What is acid-dissociation constant?</h3>
The acid-dissociation constant is a constant that shows the extent of dissociation of an acid in solution. We have to set up the reaction equation as shown below;
Let the acid be HA;
HA + H2O ⇄ H3O^+ + A^-
since the pH of the solution is 2.57 then;
[H3O^+] = Antilog(-pH) = Antilog(-2.57) = 2.7 × 10^-3
We can see that; [H3O^+] = [A^-] so;
Ka = (2.7 × 10^-3)^2/(5.5 × 10^–3)
Ka = 1.3 × 10^-3
