The shells of various sea creatures and the shells of the eggs of birds and reptiles are all made of calcium carbonate. Let us look at the reaction that takes place: \(\begin{array}{l}Ca^{2+}_{(aq)} + CO^{2-}_{3(aq)} \; \rightarrow \; CaCO_{3(s)}\end{array} \) ...
compounds can only be broken down to simpler substances through a chemical reaction Compounds The properties of the elements that make up a compound are often quite different from the properties of the compound itself Sodium – Na = highly reactive metal Chlorine – Cl = poisonous gas Sodium Chlo...
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...
