Zina [86]

Answer:

Explanation:

n CaCO3 = mass / m.wt

             = 500  /( 40 + 12 + 16x 3)

           =   5 mole

n CaO = 5 moles  ( from the balanced equation we have 1:1 moles )

mass of CaO = nCaO X m.wt

                       5 x(  40 +16 )

                 =   280 grams

How do hydroxyl ions and hydronium ions affect pH?
Nookie1986 [14]
Hydroxyl ions are OH⁻ while hydronium ions are H₃O⁺ which is essentially H⁺ ions. The formula for pH is: pH = -log[H⁺]. So, the greater the concentration of H⁺ is, the lower the pH which indicates acidity. On the other hand, the greater the concentration of OH⁻, the greater the pH which indicates basicity. This is also a consequence of the equation: pH + pOH = 14.
