Q
What is a balanced chemical equation? Why should chemical equations be balanced? b) Aluminium burns in chlorine to form aluminium chloride (AlCl3). Write a balanced chemical equation for this reaction. c) Potassium metal reacts with water to give potassium hydroxide and hydrogen gas. Write a balanced chemical equation for this reaction.
A
- A chemical equation can be written by balancing total number of atoms of each element in reactants and A chemical equation should be balanced so that it can follow Law of conservation of mass.
- 2Al + 3Cl2 → 2AlCl3
- 2K + 2H2O → 2KOH + H2
