What is the sum of all the coefficients in the molecular equation for the reaction of sodium hydroxide with iron (II) sulfate?

in this task you will need to write down the equations of chemical reactions and determine the name of the products of the obtained compounds.
2NaOH + FeSO4 = Fe (OH) 2 + Na2SO4.
The total of all odds is 2 + 1 + 1 + 1 = 5.
this reaction is called an exchange reaction. When sodium hydroxide interacts with ferrous sulfate, the resulting compounds are called ferrous hydroxide and sulfate. Ferrous hydroxide has a characteristic black color.
