Answer:
5
Explanation:
According to this question, the chemical reaction is between Cobalt chloride (CoCl2) and sodium carbonate (Na2CO3) to produce Cobalt carbonate (CoCO3) and sodium chloride (NaCl).
The chemical equation is as follows:
CoCl2 + Na2CO3 ---> CoCO3 + NaCl
However, this equation is not balanced and needs to be with the use of coefficients. The balanced equation is:
CoCl2 + Na2CO3 ---> CoCO3 + 2NaCl
The sum of coefficients on the reactants side is 2 while the sum of coefficients on the product side is 3, hence, the total sum of all products and reactants is 5
In the balanced equation of the reaction of cobalt chloride and sodium carbonate reacting to form cobalt carbonate and sodium chloride, the sum of the coefficients for all the products and reactants is equal to 5.
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.
We will balance it using the trial and error method.
CoCl₂ + Na₂CO₃ ⇒ CoCO₃ + NaCl
We have 2 Cl atoms on the left and 1 Cl atom on the right. The same happens for Na. Thus, we can get the balanced equation by multiplying NaCl by 2.
CoCl₂ + Na₂CO₃ ⇒ CoCO₃ + 2 NaCl
The sum of the coefficients for all the products and reactants is:
1 + 1 + 1 + 2 = 5
In the balanced equation of the reaction of cobalt chloride and sodium carbonate reacting to form cobalt carbonate and sodium chloride, the sum of the coefficients for all the products and reactants is equal to 5.
