Answer:
coefficient 3 is needed t with water molecule to balance the equation.
Explanation:
Chemical equation:
Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Balanced chemical equation:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
The equation is balanced. There are two iron three sulfate six hydrogen and three oxygen atoms are present on both side of equation.
The given equation completely follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Coefficient with reactant and product:
Fe₂O₃ 1
H₂SO₄ 3
Fe₂(SO₄)₃ 1
H₂O 3
So coefficient 3 is needed t with water molecule to balance the equation.
Answer:
Tetrahedral. Tetra- signifies four, and -hedral relates to a face of a solid; “tetrahedral” literally means “having four faces. ” This shape is found when there are four bonds all on one central atom, with no lone electron pairs. In accordance with the VSEPR theory, the bond angles between the electron bonds are 109.5o ...
