Strontium Hydroxide Ionizes as follow,

                                       Sr(OH)₂   →   Sr²⁺  +  2 OH⁻
So,
1 mole of Sr(OH)₂ produces 2 moles of Hydroxides,

If the concentration of 1 M Sr(OH)₂ produces 2 M OH⁻ ions then, 0.082 M Sr(OH)₂ will produce,

                                  [OH⁻]  =  2 × 0.082

                                  [OH⁻]  =  0.164 M

Which statement correctly compares electric charge with electric current?
Arisa [49]

Answer:

Your answer would be D) They both require a movement of charged particles

Explanation:

In short terms both the charge and the current are made up of charged particles that are always moving, they constantly move to well... stay charged, if they stopped, then the charge would fade until there is nothing left, and if there is nothing left -it means there would be no electricity to use
