The conductivity would decrease because the concentration of ions decreases.
As barium hydroxide, a solution is added to sulphuric acid, the Barium ions replace the hydrogen ions to form a precipitate. An insoluble solid doesn't contribute ions and as such the forming of the solid barium hydroxide would mean a decrease in the concentration of the ions.
Coins or anything copper
Explanation
They are everyday objects that turn green.
The charge is a little negative
E = m c²
where E = energy released
m = mass of the nucleus
C= velocity of light
m = 9.106 x 10⁻³ x 1.67 x 10⁻²⁷ kg
C = 3 x 10⁸ m/s and C² = 9 x 10¹⁶
E = 1.37 x 10 ⁻¹² J
Answer:
C
Explanation:
Temperature, humidity, and pressure are all the same through an air mass.
