Answer:
Subtracting the number of protons from the atomic mass.
Answer: The molecular formula will be
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
To calculate the molecular formula, we need to find the valency which is multiplied by each element to get the molecular formula.
The equation used to calculate the valency is:
empirical mass of
Molecular mass= 214 g/mol
Thus molecular formula will be
Answer:
a.
b.
c.
Explanation:
Hello!
In this case, since the reaction between sodium hydroxide and iron (III) sulfate yields iron (III) hydroxide, an insoluble base, and sodium sulfate, a soluble salt, we can write the molecular equation as shown below:
a.
Now, for the total ionic equation, we make sure we separate the aqueous species in ions (dissociation) in order to write:
b.
Finally, the net ionic equation comes up by cancelling out the spectator ions, those at both reactants and products sides:
Or just:
c.
