______________1. __CaCO3 + __ H3PO4 __Ca3(PO4)2 + __CO2 + __H2O

______________2. __SbCl3 + __(NH4)2S __Sb2S3 + __NH4Cl

_____________ 3. __B2Br6 + __HNO3 __B(NO3)3 + __ HBr

_____________ 4. __KNO3 __KNO2 + __O2

_____________ 5. __Fe + __H2SO4 __Fe2 (SO4)3 + __H2

Answer 1

Answer:

In order to balance the chemical equation, you need to make sure the number of atoms of each element on the reactant side is equal to the number of atoms of each element on the product side. In order make both sides equal, you will need to multiply the number of atoms in each element until both sides are equal.

Examples of Balancing Chemical Equations

Example 1. C5H12 + O2 ---> CO2 + H2O..

Example 2. Zn + HCl ---> ZnCl2 + H2.

Example 3. Ca(OH)2 + H3PO4 ---> Ca3(PO4)2 + H2O.

Example 4. FeCl3 + NH4OH ---> Fe(OH)3 + NH4Cl.

Example 5. S8 + F2 ---> SF6 ...

Example 6. C2H6 + O2 ---> CO2 + H2O....

Example 7. Al2(CO3)3 + H3PO4 ---> AlPO4 + CO2 + H2O.
