Question

Write a balanced equation for ${\mathrm{BCl}}_3\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_3{\mathrm{BO}}_3\left(\mathrm{s}\right)+\mathrm{HCl}\left(\mathrm{g}\right)$.

Answer 1

Balanced Chemical Equation:

• A balanced chemical equation is one in which the number of atoms for all the elements is equal on both sides of the equation.

Step 1:

• Write the equation which is to be balanced.
• ${\mathrm{BCl}}_3\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_3{\mathrm{BO}}_3\left(\mathrm{s}\right)+\mathrm{HCl}\left(\mathrm{g}\right)$

Step 2:

• Balance chlorine atoms on both sides by putting $3$ in front of $\mathrm{HCl}$.
• ${\mathrm{BCl}}_3\left(\mathrm{g}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_3{\mathrm{BO}}_3\left(\mathrm{s}\right)+3\mathrm{HCl}\left(\mathrm{g}\right)$

Step 3:

• Balance hydrogen atoms on both sides by putting $3$ in front of ${\mathrm{H}}_2\mathrm{O}$.
• ${\mathrm{BCl}}_3\left(\mathrm{g}\right)+3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_3{\mathrm{BO}}_3\left(\mathrm{s}\right)+3\mathrm{HCl}\left(\mathrm{g}\right)$

Step 4:

• Cross-check that each element on both sides is balanced.
• Since the atoms of each element are balanced. the balanced equation will be:
• ${\mathrm{BCl}}_3\left(\mathrm{g}\right)+3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{H}}_3{\mathrm{BO}}_3\left(\mathrm{s}\right)+3\mathrm{HCl}\left(\mathrm{g}\right)$
