Coefficient of "1" is understood. choose option "blank" for the correct answer if the coefficient is "1." bcl3; + h2o → h3bo3 + hcl

The balanced equation is:

BCl3 + 3H2O → H3BO3 + 3HCl

The coefficients are : 1, 3, 1, 3

Explanation:

The equation for the reaction is given below :

BCl3 + H2O → H3BO3 + HCl

The above equation can be balanced as follow:

There are 3 atoms of Cl on the left side and 1 atom on the right. It can be balance by putting 3 in front of HCl as shown below:

BCl3 + H2O → H3BO3 + 3HCl

There are a total of 6 atoms of H on the right side and 2 atoms on the left. It can be balance by putting 3 in front of H2O as shown below:

BCl3 + 3H2O → H3BO3 + 3HCl

Now we can see clearly that the equation is balanced as the atoms of the different elements present on both sides of the equation are equal.

The coefficients are : 1, 3, 1, 3

idk what the question is about
