The chemical reaction that appears between the given compounds, ferrous sulfate and barium hydroxide, is a double replacement reaction. This is due to the activity series of the metals being able to replace either of them in the compound. To balance the chemical reaction, ensure that the number of moles of each of the atoms in both sides of the equation are equal.
The answer to this item is,
FeSO₄(aq) + Ba(OH)₂(aq) --> BaSO₄(s) + Fe(OH)₂ (aq)
As can be seen in the resulting equation, it does not need to be modified to balance it.
<span>the answer is 0.67 mol.

Feldspar is Soft but sometimes can be hard if a chemical reaction occurs
Answer:
Formula mass = 58.09 g
Explanation:
Formula mass of a given molecule is defined as the sum of atomic masses of elements forming the empirical formula of that molecule.
In order to calculate the formula mass of propanol, following data is required;
Empirical Formula of Propanol:
The empirical formula of Propanol is C₃H₆O (also the molecular formula) as it is the lowest possible atomic ratio of the given elements.
Atomic Masses of Elements:
Carbon = 12.01 g/mol
Hydrogen = 1.01 g/mol
Oxygen = 16.00 g/mol
Hence,
Formula mass = (At. mass of C)₃ + (At. mass of H)₆ + (At. mass of O)
Formula mass = (12.01)₃ + (1.01)₆ + (16.00)
Formula mass = 36.03 + 6.06 + 16.00
Formula mass = 58.09 g
