Step-by-Step Solution:1. Definition of Chemical Reaction: A chemical reaction is a process where one or more substances (reactants) are transformed into one or more new substances (products). This transform
Such an equation is ‘unbalanced’ because the mass is not the same on both sides. Therefore, the above equation is a skeletal chemical equation for the reaction between magnesium and oxygen. Solved Examples for You Question: Why are iron articles painted? Solution: When iron comes in contact...
