28 maj 2020 · Write an equation for the reaction. Write separate equations for the reactions of the solid metals magnesium, aluminum, and iron with diatomic oxygen gas to yield the corresponding metal oxides. (Assume the iron oxide contains Fe 3+ ions.)
Identify each of the following as examples of oxidation of reduction: a) Li( s ) Li + ( aq ) + e − = oxidation b) S( s ) + 2e − S 2− ( aq ) = reduction
Iron can react with oxygen to form iron (II) oxide. 2Fe + O 2 → 2FeO. Iron can also react with oxygen to form iron (III) oxide. 4Fe + 3O 2 → 2Fe 2 O 3. Nickel can react with oxygen to form nickel (II) oxide or nickel (III) oxide. Write two balanced symbol equations to show both reactions of nickel with oxygen. How did you do? Stuck?
Write balanced chemical equations corresponding to each of the following descriptions: (c) When hydrogen gas is passed over solid hot iron (III) oxide, the resulting reaction produces iron and gaseous water.
When iron rusts, solid iron reacts with gaseous oxygen to form solid iron (III) oxide. Write a balanced chemical equation for this reaction. The balanced chemical equation for the reaction of iron rusting is: 4Fe + 3O₂ → 2Fe₂O₃. First, identify the reactants and products involved in the reaction.
For each of the following problems, write complete chemical equations to describe the chemical process taking place. Important note: There are a few physical processes on this sheet – remember, you can’t write an equation for a physical process! 1) When lithium hydroxide pellets are added to a solution of sulfuric acid,
a) Aluminum metal reacts with iron (II) oxide powder to produce aluminum oxide solid and iron metal. _____ b) Aluminum sulphate solution and calcium hydroxide solution produce a precipitate of aluminum hydroxide and solid calcium sulphate. _____ c) Ammonia gas (NH 3) plus oxygen gas yields nitrogen monoxide gas plus water vapour.
