You first write the equation using letter variables for the coefficients: aCaCO3 +bH3PO4 → cCa3(PO4)2 + dH2CO3. .

Instead of the inspection method, shown in most chemistry texts, a more general method of balancing chemical reaction equations is the algebraic method, proposed by the Russian academician, V.
Video 1: Introduction to Balancing Chemical Equations.
Tip: Unless there is evidence for decomposition , then you should treat compound ions, such as $\rm CO_3^{2-}, NO_3^{-}$ et cetera, as single units rather than collections.
Balancing more complex chemical equations.
Balancing chemical equation with substitution.
The answer will appear below.
Oxidation number change method.
This not only gives you the correct.
Step 3: Finally, the balanced chemical equation will.
As you get more familiar with this idea, you may want to graduate to the “algebraic” method of balancing chemical equations.
The value of ‘b’ can be obtained by substituting the values of a, c and d in the equation; 6×1 + 2b = 2×6 + 6.
