Question

50 examples of unbalanced chemical equations with answers

Answer 1

Hydrogen and oxygen react to form water.

H2+O2---->H2O

Now balance this chemical equation

2H2+O2----->2H2O

The number of hydrogen and oxygen on both sides is equal

Answer 2

Answer:

1) Lithium hydroxide reacts with sulfuric acid to form lithium sulfate and water.    LiOH + H2SO4 → Li2SO4  +H20

2) Magnesium reacts with Sodium Fluoride and forms Magnesium Fluoride and Sodium metal.  Mg + NaF → MgF2 + Na

3) Copper reacts with Silver nitrate solution to form Copper (II) Nitrate and silver.   Cu + AgNO3 → CuNO3 + Ag.

4) Glucose burnt in Oxygen t o form Carbon dioxide and water.

    C6H12O6 + O2 → CO2 + H2O

5) Calcium Carbonate reacts with Hydrochloric Acid to form  Calcium Chloride,  water and carbon dioxide. CaCO3 + HCl → CaCl2 + H2O + CO2

Explanation:

1) Balanced chemical Equation would be:

                               2LiOH + H2SO4 → Li2SO4 + H20.

2) Balanced chemical Equation would be:

                               Mg + 2NaF → MgF2 + 2Na2

3) Balanced chemical Equation would be:

                                Cu + 2AgNO3 → Cu(NO3)2 + 2Ag

4) Balanced chemical Equation would be:

                                  C6H12O6 + 6O2 → 6CO2 + 6H2O

5) Balanced chemical Equation would be:

                                    CaCO3 + 2HCl → CaCl2 + H20 + CO2
