g Identify limiting reactants (mole ratio method). Close Problem Identify the limiting reactant in the reaction of bromine and c
love history [14]

Answer:

(i) Cl₂ is a limiting reactant

(ii) The amount of excess reactant = 4.8 g

Explanation:

                             Br₂(g) + Cl₂(g) → 2 BrCl(g) ---------------------------(i)

Calculation of no. of moles

                            Moles of Br_{2}  = \frac{weight}{Molecular weight} = \frac{29.7}{160} =0.18

                            Moles of Cl_{2}  =\frac{11.2}{71}  = 0.15 mole

Using mole ratio method to find the limiting reactant and Excess reactant.

                            \frac{Mole}{Stoichiometry} (for Br_{2} ) = \frac{0.18}{1}  = 0.18

                            \frac{Mole}{Stoichiometry}(for Cl_{2}) =\frac{0.15}{1}=0.15

So Cl_{2} is a limiting reactant and Br₂ is excess reactant.

The amount of excess reactant = 0.18 - 0.15 = 0.03 mole = 4.8 g

224 x 10' is incorrect scientific notation, how should this be written in correct scientific notation?
riadik2000 [5.3K]

Answer:

2.24 x 10^3

Explanation:

When writing in scientific notation, you need to simplify the subject till there's only one digit on the left of the decimal point, so in this problem you had to move the decimal point over two more places.

It has already been moved once, shown by the 10^1, so you add 2 to the 10^1 to get 10^3.
