According to the "Law of Conservation of Mass", mass can neither be created nor destroyed in a chemical reaction. That is, the total mass of the elements present in the products of a chemical reaction has to be equal to the total mass of the elements present in the reactants. In other words, the number of atoms of each element remains the same, before and after a chemical reaction. Hence, we need to balance a skeletal chemical equation.1. Mg + O2 \(\longrightarrow\) MgO is the given chemical equation balanced?(i) YES(ii) NO2. Which of the following steps are involved in writing a balanced chemical equation?(i) Word equation is written in formula form(ii) Boxes are drawn around each formula and nothing is changed inside these boxes(iii) Number of atoms of different elements present in unbalanced equation are listed(iv) All of the above3. Which of the following represents a balanced chemical equation?(i) 2Mg + O2 \(\longrightarrow\) 2MgO(ii) Mg + O2 \(\longrightarrow\) 2MgO(iii) Mg + O2  \(\longrightarrow\) MgO(iv) 2Mg + O2 \(\longrightarrow\) MgO4. Why we should balance a chemical equation?(i) To follow law of conservation of mass(ii) To make the number of the atoms of the reactants equal to the number of the atoms of the products(iii) To make total mass of the reactants equal to the mass of the products(iv) All of the above5. State true or false: Word equation is a balanced chemical equation(i) TRUE(ii) FALSE
