To balance H in Cr2O72- (aq) → Cr3+ (aq) + 7H2O (in acidic medium), we will
Add 14H+ on left side
Add 4H+ on left side
Add 14H+ on right side
Add 4H+ on right side
To balance H in Cr2O72- (aq) → Cr3+ (aq) + 7H2O (in acidic medium), we will add 14H+ on left side.
Cr2O72- (aq) + 14H+ → Cr3+ (aq) + 7H2O
We can balance the following ionic equation by adding
6Fe2+(aq) + Cr2O72-(aq) → 6 Fe3+(aq) +2Cr 3+(aq)
In figure 1, left-hand side (LHS) and the right-hand side (RHS) of the weighing machine are equal to each other. If we add 2 on the RHS, as shown in figure 2, what should we do to equalise LHS and RHS again?
Angles on one side of a straight line always add to ______.
