Answer:
The reaction is classified as strong acid+ weak base
Explanation:
Answer:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
Explanation:
Step 1: Write out unbalanced reaction
Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Step 2: Balance
We need the same number of SO₄²⁻ on each side
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Now we need the same amount of H⁺ on each side
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
Answer: Chemical equation
Explanation: In writing a chemical equation, the correct formula and symbols of the reactants are written on the left hand side of the equation while those of the products are written on the right hand side. A horizontal arrow is drawn between the two sides to indicate the direction of the reaction.
Example: Na + Cl -> NaCl
<span><span>1. </span><span>Fe2O3 or Iron (III)
oxide is an organic compound. It contains 3 main oxides of Iron, the iron (II)
oxide (FeO) and the iron (II, III) oxide (Fe3O4).
Now, let’s find the number of Molecules are there in 79g of Fe203:
The number of Atoms are there:
Molar Mass of Fe2O3 = 160g / mol.
=> 160g of Fe2O<span>3 </span>= 6.02 x 1023 Molecules
=> 79g of Fe2O3 = x
Next, find the value of X, in where:
x = (6.02 x 1023 x 79g) / 160g is approximately
x = 2.97 x 1023 molecules.</span></span>
