halogen
Explanation:
It belongs to Group 17 on the periodic table, which is a halogen
Answer:
Fe + CuO ----> FeO+ Cu
Explanation:
A word equation is a chemical equation in which the reactants and products are represented by words rather than the respective symbols of the species involved in the reaction.
Generally, when writing a balanced reaction equation, it is normal to ensure that the number of atoms of each element on the reactant side is the same as the number of atoms of the same element on the product side. This has been ensured in the reaction above.
The reaction above is possible because iron is higher than copper in the electrochemical series hence iron can displace copper from its compounds.

You'll need to react
7,5 moles of Sodium with sulfuric acid to produce 3.75 moles of sodium sulfate
</span>
First of all, you need to balance the reaction. The balanced reaction is shown below (ensuring that the Law of Conservation of Mass is met on both sides):
2Na + H₂SO₄ → Na₂SO₄ + H₂
Now, all that you have to do is to use molar equivalences in this reaction applying the coefficients to calculate the moles of Sodium that you'll need:
