Answer:
0.0521 M
Explanation:
HClO2 + NaOH ---> NaClO2 + H2O
M(HClO2)V(HClO2) = M(NaOH)V(NaOH)
M(HClO2)*41.6 mL = 0.146 M*14.85 mL
M(HClO2) = 0.146*14.85/41.6 M = 0.0521 M
Answer:
Static electricity is a type of energy that is produced by friction.
Explanation:
Static electricity may be the result when there is an imbalance between the negative charges and the positive charges in the surroundings. They are non contact forces. They pull of push without actually touching the body. The charged particles interact by pulling or pushing the uncharged particles.
These charges are released when they come closer to some uncharged or other charged particles like the electrostatic charges. It is the charge build up in an area.

Answer:
5.6
Explanation:
since HCl is a strong acid we know that it completely dissasociates into H+ and Cl-
We can just treat the HCl as the H+ concentration and take the -log
-log(2.5E-6) = 5.6
