(b)
Interpretation:
The balanced equation for the reaction of iron wool with oxygen gas to produce solid iron
Concept introduction:
A balanced chemical equation represents an equation in which all the reactants and products are written with their stoichiometric coefficient and physical states. The number of atoms of an element on the both sides of the equation is equal.

- The tarnish that appears on silver is silver sulfide, which is formed when silver is exposed to sulfur-bearing compound in the presence of oxygen in the air. When hydrogen sulfide is the sulfur-bearing reacting compound, water is the second product. Write the equation for the reaction.arrow_forwardApply Describe the reaction of aqueous solutions of sodium sulfide and copper(ll) sulfate, producing the precipitate copper(ll) sulfide.arrow_forwardThe Group 2 metals (Ba, Ca, Sr) can be produced in the elemental state by the reaction of their oxides with aluminum metal at high temperatures, also producing solid aluminum oxide as a by-product. Write the unbalanced chemical equations for the reactions of barium oxide, calcium oxide, and strontium oxide with aluminum.arrow_forward
- When steel wool (iron) is heated in pure oxygen gas, the steel wool bursts into flame and a fine powder consisting of a mixture of iron oxides ( FeO and Fe2O3 ) forms. Write separate unbalanced equations for the reaction of iron with oxygen to give each of these products.arrow_forwardSodium hydroxide is added to phosphoric acid.arrow_forward
