A common demonstration in chemistry courses involves adding a tiny speck of manganese(IV) oxide to a concentrated hydro- gen peroxide (H₂O₂) solution. Hydrogen peroxide decomposes quite spectacularly under these conditions to produce oxygen gas and steam (water vapor). Manganese(IV) oxide is a catalyst for the decomposition of hydrogen peroxide and is not consumed in the reaction. Write the balanced equation for the decomposition reaction of hydrogen peroxide. 92. Iron oxide ores, commonly a mixture of FeO and Fe,O,, are given the general formula Fe,O,. They yield elemental iron when heated to a very high temperature with either carbon monoxide or elemen- tal hydrogen. Balance the following equations for these processes: Fe,O(s) + H₂(g) Fe 0,(s) + CO(e) Fe(s) + H₂O(e) Fe(s) + CO)

1. In Ontario, some electricity comes from coal-burning generators. Coal is a natural form of carbon that has a large amount of sulphur mixed in with it. Here are the balanced equations for the combustion of coal and sulphur: carbon + oxygen → carbon dioxide C + O 2 → CO 2 sulphur + oxygen → sulphur dioxide S + O 2→ SO 2 Answer the following questions based on the burning of coal to produce energy: a) In what way is the combustion of sulphur harmful to the environment? b) Write the word equation and balanced chemical equation for the reaction that produces this harmful environmental effect. My Answers I am not sure how if part b) is right or how to balance it. This is the complete question. a) The combustion of sulphur produces sulphur dioxide (SO2). b) Word Equation: sulphur dioxide + water = sulphuric acid Balanced Chemical Equation: SO 2+ H 2O =H 2SO 3 =H 2SO4
In experiment #7, you observed the formation of carbon dioxide by reacting baking soda with vinegar. Why was it not possible to relight the candle? A. Carbon dioxide is heavier than air so it stays in the beaker preventing the candle from relighting. B. Carbon dioxide is lighter than air so it escaped from the beaker and the candle should have relit. C. Carbon dioxide is heavier than air so it stays in the beaker and the candle should have relit. D. Carbon dioxide is lighter than air so it escaped from the beaker preventing the candle from relighting.
How could you have used the color change property of iron(III) chloride to monitor when the reaction had reached completion? You could have added drops of iron(III) chloride directly to the reaction mixture until a change in color occurred. You could have placed a drop of iron(III) chloride directly to the reaction mixture and waited until the color disappeared. You could have placed a drop of reaction mixture every minute in one test tube containing iron(III) chloride until there was no color change. You could have placed a drop of reaction mixture into different test tubes containing iron(III) chloride every minute until there was no color change. Incorrect

A student weighs out 4.16 g of magnesium chloride and adds enough water to make 125.0 mL of solution. The student then weighs out 8.82 g of sodium phosphate and adds enough water to make 250.0 mL of solution. 25.0 mL of the magnesium chloride solution is combined with 25.0 mL of the sodium phosphate solution. a. Write a balanced equation for the reaction that occurs (remember to include phases). b. If a precipitate forms, write the name of the precipitate and calculate the theoretical yield for the precipitate. If no precipitate forms, calculate the limiting reactant. c.
