Question

Write balanced chemical equations for the following: [4]

a) Al3+O2 --> Al2O3

b) KClO3 ---> KCl + O2

c) KMnO4 + HCl ----> KCl + MnCl2 + Cl2+ H2O

d) P2O5 + H2O---> H3PO4​

Answer 1

Answer:

Explanation:

To be useful, chemical equations must always be balanced. Balanced chemical equations have the same number and type of each atom on both sides of the equation. The coefficients in a balanced equation must be the simplest whole number ratio. Mass is always conserved in chemical reactions.
