WebMany important processes that occur in the body depend on the movement of ions across the outer surfaces of cells. For example, in our bodies, the nervous and muscular systems use the electrolyte properties of ionic sodium and potassium to move across the outer surfaces of cells near muscles and nerve cells that create impulses which in turn is seen … Web29 sep. 2016 · 1 Answer anor277 Sep 29, 2016 1 mole of ferric sulfate contains 2 moles of iron, and 12 moles of oxygen atoms, and three moles of sulfate ions. Explanation: Here, we use the mole as we would use any other collective number: a dozen eggs; a Bakers' dozen; a Botany Bay dozen. WebThe HCO₃⁻ ion dissociates as follows - HCO₃⁻ ⇌ H⁺ + CO₃²⁻ This is the second-degree dissociation reaction. The total molecules of HCO₃⁻ ions = 100. The 1% of HCO₃⁻ ion = [(1 / 100)] 100 = 1. Hence, 1 ion of HCO₃⁻ ion dissociates and gives 1 H⁺ ion and 1 CO₃²⁻. cryptographic operation 0x80090016
