<h2>We get the following information from a chemical equation :--</h2>
1. We get the symbol and formulas of the reactants and products.
2. The physical state of the reactants and products.
3. From this reaction, we can know the molecular formula of ammonia, water and nitrogen.
4. Here all the species are in a gaseous state.
5. The reaction takes place at a high temperature and pressure.
6. Zinc metal reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas. This equation is written as:
Zinc metal reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas. This equation is written as: Zn+H2SO 4→ZnSO 4 +H2.
Isotopes.
ISO means equal
Topo means position
Are substances that occupy the same position in the periodic table becomes they have the same number of protons but they differ on the number of neutrons and in consequence they have different mass
