In an ionic solution, a current consists of Ca2+Ca2+ ions (of charge +2e+2e) and Cl−Cl− ions (of charge −e−e) traveling in opposite directions. Part A If 5.02×1018 Cl−Cl− ions go from A to B every 0.620 minmin , while 3.25×1018 Ca2+Ca2+ ions move from B to A, what is the current (in mAmA) through this solution? Part B In which direction (from A to B or from B to A) is the current in part A going?

A

The current through the solution is  

B

The current is moving from B to A

Explanation:

From the question we are told that

      The number of   that move from A to B is

      The time taken to move from A to B  

Since the value of 1 charge is  

The quantity of charge Q that flow from A to B is mathematically given as

   The number of   that move from A to B is

      Since time taken to move from A to B is equal to time taken to move from B to A  

The quantity of charge Q that flow from B to A is mathematically given as

The total quantity of charge is

The current flowing through the solution is

The flow is from B to A cause current  flow from the positive terminal to negative terminal

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
