(a)
Interpretation:
The balanced equation for the reaction of treatment of finely divided gold with CN-(aq) in the presence of O2 (g) should be written.
Concept introduction:
The balanced chemical equation can be written by following a few steps:
Step 1: Writing the correct skeleton and molecular formula for the element or molecules on either side of the equation.
Step 2: Counting the
Step 3: Balancing the number of that atom or group on either side which has large atoms in number.
Step 4: Using the correct coefficients to balance the number of atoms on both sides.
(b)
Interpretation:
The balanced equation for the reaction of treatment of finely divided zinc metal with solution formed in part (a) should be written.
Concept introduction:
The balanced chemical equation can be written by following a few steps:
Step 1: Writing the correct skeleton and molecular formula for the element or molecules on either side of the equation.
Step 2: Counting the number of atoms of each element on either side of the equation.
Step 3: Balancing the number of that atom or group on either side which has large atoms in number.
Step 4: Using the correct coefficients to balance the number of atoms on both sides.
