Properties of Protons: Positively charged particles in the nucleus (center) of an atom.
Properties of Neutrons: Neutral particles that have no electric charge in the nucleus.
Properties of Electrons: Found outside the nucleus of the Atom..
I hope this helps! :)
Answer:
Explanation:
HCl is strong acid, hence 0.04M of acid
= 0.057 M of H+
pH = -log [H+]
= -log [0.057]
= 1.244
Let the dissociation of trichloroacetic acid be:
HClO4 --> H^+ + ClO4^-
HA --> H+ + A-
0.072 - x x x
[H+] = 0.057 M
[HA] = 0.072 - 0.057
= 0.015 M
[H+] = [A-] = 0.057
Ka = [H+][A-]/[HA]
= (0.057^2)/(0.015)
= 0.217
= 0.22.
Latitude and longitude are the x and y axis on a grid. When you're trying to find a location on earth, you need to graph it, so you can pinpoint the location. There is no grid if there is no longitude and/or latitude lines. Without one of the lines, it would be very hard to graph, which will be difficult in finding locations on earth. But hey, I'm not too sure. I recommend looking at other people's answers too and searching it up.
