Writing Chemical Equations
Section 4H: On the worksheet we completed today in class, indicate for each question (1-12) which type of chemical reaction is being represented. Then, complete Part E in the packet we started in class yesterday. Finally, write the reaction equations for the following:
1) Magnesium metal reacts with oxygen gas to produce solid magnesium oxide.
2) Sulfur dioxide gas reacts with gaseous water to produce aqueous hydrogen sulfite.
3) Solid calcium carbonate reacts to form solid calcium oxide and carbon dioxide gas.
4) Potassium chlorate reacts to form potassium chloride and oxygen.
Section 4: If you have not already, complete the worksheet we started today in class. Then, write the reaction equation (or sentence) for the following:
1) Magnesium metal reacts with oxygen gas to produce solid magnesium oxide.
2) Sulfur dioxide gas reacts with gaseous water to produce aqueous hydrogen sulfite.
3) Solid calcium carbonate reacts to form solid calcium oxide and carbon dioxide gas.
4) Potassium chlorate reacts to form potassium chloride and oxygen gas.
5) Magnesium metal reacts with aqueous hydrochloric acid to produce aqueous magnesium chloride and hydrogen gas.
6) Aqueous copper (II) sulfate reacts with magnesium metal to produce copper metal and aqueous
magnesium sulfate.
7) Solid lead (II) sulfide reacts with aqueous hydrochloric acid to produce solid lead (II) chloride and
hydrogen sulfide gas.
8) Cr(NO3)3 + H2S → Cr2S3 + HNO3
