Question

balance the following chemical equations
pls do answer correctly with the right process!
please help!!!!!!!!!!!!
​

Answer 1

AnswErs:-

• $\rm 2Mg + O_2 \rightarrow 2MgO.$

• $\rm 2H_2 + O_2 \rightarrow 2H_2O.$

• $\rm 2Na+Cl_2\rightarrow 2NaCl.$

• $\rm N_2+3H_2\rightarrow 2NH_3.$

• $\rm 4Na+O_2\rightarrow 2Na_2O.$

VerificaTion:-

$\begin{tabular}{|c|c|c|c|}\cline{1-4} Equation No. & Element or Atom & Atoms in reactant & Atoms in product \\ \cline{1-4} 1 & Mg & 2\times 1 = 2 & 2\times 1 = 2 \\ \cline{2-4} & O & 1\times 2 = 2 & 2\times1 = 2 \\ \cline{1-4} 2 & H & 2\times2 = 4 & 2\times2 = 4 \\ \cline{2-4} & O & 1\times2 = 2 & 2\times1 = 2 \\ \cline{1-4} 3 & Na & 2\times1 = 2 & 2\times1 = 2 \\ \cline{2-4} & Cl & 1\times2 = 2 & 2\times2 = 2 \\ \cline{1-4} 4 & N & 1\times2 = 2 & 2\times1 = 2 \\ \cline{2-4} & H & 3\times2 = 6 & 2\times3 = 6 \\ \cline{1-4} 5 & Na & 4\times1 = 4 & 2\times2 = 4\\ \cline{2-4} & O & 1\times2 = 2 & 2\times1 = 2\\ \cline{1-4} \end{tabular}$

More Related Information:-

• We need to balance the chemical equations because of the law of conservation of mass.

• Law of conservation ofass states that Mass can neither be created nor being destroyed in a chemical reaction.

• Thats why the number of atoms in both the reactants as well as products must be same ofball elements which can be done by balancing the chemical equations.
