Importance of chemical names and symbols over common names.

Answer Text:
Importance of chemical names and symbols over common names.
1. Chemical names and symbols indicate the names in the compounds.
Examples:
- Compounds whose names end in -ide; contains only two elements;
Iron (II) sulphide: iron and sulphur;
Magnesium nitride: magnesium and nitrogen;
- Compounds whose names end in – ate contain three elements and oe of them is oxygen;
2. Chemical names are universally known and accepted; hence provide mean of easy communication amongchemists all over the world;
Simple word equations.
Equations:
- Is a linear summary of a chemical reaction, showing the reactants and products.
Examples:
Copper (II) oxide + hydrogen → copper + water;
Explanations:
- Substances on the left hand side are called reactants;
- Substances on the right hand side are called
products;
- The addition sign (+) on the left hand side means “reacts with”;
- The arrow (→) means to form;
- The addition sign (+) on the right hand side (products side) means “and”.
Conclusion:
Copper (II) oxide reacts with hydrogen to form copper and water;
Note:
- Some chemical reactions are reversible and hence have two opposite arrows ( ) between reactants and products
- The arrows ( ) in chemistry means a reversible chemical reaction;
Further examples:
1. Copper (II) carbonate → Copper (II) oxide + carbon (IV) oxide;
2. Magnesium + oxygen → magnesium oxide;
