However, we know from the law of conservation of matter that atoms can’t be created or destroyed. In other words, we can’t just get rid of an iron atom or create an oxygen atom to make the equation work. Nor can we change the subscripts in the reaction, because doing so would sug...
rust. This is called rusting of iron. During the rusting of iron, iron metal combines with the oxygen (of air) in the presence of water (moisture) to form a compound ‘iron oxide’. This iron oxide is rust. The process of rusting can be represented by the following word equation : ...
This is known as a word equation. By writing the symbols and formulae of the various substances in place of their names, we can convert this word equation into a chemical equation. Now, we know that the symbol of zinc is \(\text {Zn}\) ...
Balance Equation ➜ Instructions To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above. Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, ...
These substances are the compo-nents of the chemical reaction system; those components which decrease in quantity arecalled reactants, while those that increase are products. A given chemical reaction system isdefined by a balanced net chemical equation which is conventionally written asreactants ...
