what fraction of total current is carried by K+ ions when current flows through a solution...
When a current passes through the body, it is mainly carried by positively charged sodium ions (Na+) with charge +e and negatively charged chloride ions (Cl−) with charge −e. In a given electric field, these two kinds of ions do not move at the same speed; the chloride ions move 50% faster than the sodium ions. Part A If a current of 190 μA is passed through the leg of a patient, how many chloride ions pass a cross section...
When potassium ions (K+) cross a membrane through an ion channel, they acquire a velocity on the order of 10-2 m/s. Approximately what are the minimum and maximum values of the magnetic force on a K+ due to Earth’s magnetic field?

In an ionic solution, a current consists of Ca2+ ions (of charge +2e) and Cl− ions (of charge −e) traveling in opposite directions. If 5.15×1018 Cl− ions go from A to B every 0.530 min , while 3.24×1018 Ca2+ ions move from B to A, what is the current (in mA) through this solution? Part A) If 5.15×1018 Cl− ions go from A to B every 0.530 min , while 3.24×1018 Ca2+ ions move from B to A, what is...
What mass of gold is produced when 7.20 A of current are passed
through a gold solution for 37.0 min ?
Express your answer with the appropriate units.
t Gold Electroplating 6 of 6 Constants| Periodic Table Part A Metal plating is done by passing current through a metal solution. For example, an item can become gold plated by attaching the item to a power source and submerging it into a Au+ solution. The item itself serves as the cathode,...
