- 3.87 Nitric acid (HNO3) can be produced by the reaction of ni- trogen dioxide (NO2) and water. Nitric oxide (NO) is also formed as a product. Write a balanced chemical equation for this reaction.arrow_forward3.18 Diborane and related compounds were proposed as rocket fuels in the 1950s. A representative reaction for this class of molecules is that of B2H6 and O2 to form B2O3 and H2O. Write the balanced chemical equation for this process.arrow_forward4.106 An ore sample with a mass of 670 kg contains 27.7% magnesium carbonate, MgCO3. If all of the magnesium carbonate in this ore sample is decomposed to form carbon dioxide, describe how to determine what mass of CO2 is evolved during the process.arrow_forward
- What does it mean to say an equation is balanced? Why is it important for an equation to be balanced?arrow_forwardIron oxide ores, commonly a mixture of FeO and Fe2O3, are given the general formula Fe3O4. They yield elemental iron when heated to a very high temperature with either carbon monoxide or elemental hydrogen. Balance the following equations for these processes: Fe3O4(s)+H2(g)Fe(s)+H2O(g)Fe3O4(s)+CO(g)Fe(s)+CO2(g)arrow_forwardBalance the following equations representing combustion reactions: a. b. c. C12H22O11 (s) + O2(g) CO2 (g) + H2O (g) d. Fe(s) + O2(g) Fe2O3(s) e. FeO(s) + O2(g) Fe2O3(s)arrow_forward
