Question
What are the steps involved in writing the skeletal equation?
✓
Answer
The following are the steps involved in writing the skeletal equation:
1. Write the symbols and formula of each of the reactants on the left hand side (LHS) and join them by plus ( + ) sign.
2. Follow them by an arrow $(\rightarrow)$ which is interpreted as gives or forms.
3. Write on the right hand side (RHS) of arrow the symbols and formula for each of the products.
4. The equation thus written is called as skeleton equation (unbalanced equation).
5. If the product is a gas it should be represented by upward arrow ( $\uparrow$ ) and if it is a precipitate it should be represented by downward arrow ( $($ ). Example: $Mg + H _2 SO _2 \rightarrow MgSO _4+ H _2 \uparrow$
