Final answer:
The student's request was to write chemical equations in symbols and formulae for a set of word equations. The equations provided include the formation of silver chloride, magnesium oxide, iron(III) sulfide, carbon dioxide, and calcium oxide, all of which are balanced and represent key reactions in chemistry.
Step-by-step explanation:
The task at hand is to write the chemical equations in symbols and formulae based on given word equations. The correct balanced chemical equations for the provided reactions are as follows:
- a. Silver reacts with chlorine gas to form silver chloride: 2Ag(s) + Cl₂(g) → 2AgCl(s)
- b. Magnesium reacts with oxygen to form magnesium oxide: 2Mg(s) + O₂(g) → 2MgO(s)
- c. Iron reacts with sulfur to form iron(III) sulfide: 2Fe(s) + 3S(s) → Fe₂S₃(s)
- d. Carbon reacts with oxygen to form carbon dioxide: C(s) + O₂(g) → CO₂(g)
- e. Calcium reacts with oxygen to form calcium oxide: 2Ca(s) + O₂(g) → 2CaO(s)
These balanced equations are fundamental in studying chemical reactions and stoichiometry in chemistry.
