Question

Balance the following reaction. A coefficient of "1" is understood. Choose option "blank" for the correct answer if the coefficient is "1." BCl3; + H2O → H3BO3 + HCl

Answer 1

Answer : A complete balanced chemical equation is the one where every element has the number equivalent on both the sides of the reaction i.e. on reactant and product side.

Here, $BCl_{3} + H_{2}O ---> H_{3}BO_{3} + HCl$

Now, we have to check for the same number of elements on either side of the reaction

By looking at the reaction B is only 1 so it is balanced;

Cl is 3 on reactant side but 1 on product side...(needs to be balanced)

H is 2 on reactant side and 4 on product side...(needs to be balanced)

O is 1 on reactant side and 3 on product side...(needs to be balanced)

So, multiplying with 3 and rearranging the equation with their co-efficients we get;

$BCl_{3} + 3H_{2}O ---> H_{3}BO_{3} + 3HCl$
