2 Each term may be used once, more thanonce, or not at fuel for the space shuttle is hydrogen, which burns in oxygen to produce water vaporand energy. In this chemical reaction, hydrogen is a(n) (9), oxygenis a(n) (10), and water vapor is a(n) (11). Ina chemical equation for this reaction, a(n) (12)is used to separatehydrogen and oxygen from water vapor and energy. A(n) (13)isused to separate the symbols for hydrogen and oxygen. A(n) (14)symbol is used to tell the state of hydrogen in the reaction, a(n) (15)symbol is used for the state of oxygen, and a(n) (16)symbol is usedfor the state of water Guide FOR Content MASTERYCHAPTER10arrowplus sign(s)(l) reactantproduct(g)(aq)Copyright Glencoe/McGraw-Hill, a division of the McGraw-Hill Companies, : Matter and Change Chapter 10 Study Guide for Content MasteryFor each of the following chemical reactions, write a word equation, a skeleton equation,and a balanced chemical equation.

3 Be sure to show the state of each reactant and prod-uct. If you need more help writing formulas or determining the state of a substance,refer to Chapters 8 and 9 and the periodic table on pages 156 mercury(II) oxide breaks down when heated, forming the elements mercury metal reacts with water vapor in air to form solid sodium hydroxide and the first step of refining zinc metal from its zinc sulfide ore, the ore is heated in thepresence of oxygen. The products are solid zinc oxide and sulfur dioxide next step of refining zinc involves heating the zinc oxide in the presence of reaction produces zinc vapor and carbon monoxide pollutants in the air react with water vapor to form acids.

4 For example, sulfur trioxide reacts with water vapor to form sulfuric calcium carbonate is commonly used in antacids because it reacts with thehydrochloric acid found in the stomach. The products of this reaction are aqueous calcium chloride, carbon dioxide, and Guide FOR Content MASTERYCHAPTER10 Section continuedCopyright Glencoe/McGraw-Hill, a division of the McGraw-Hill Companies, Guide for Content MasteryChemistry: Matter and Change Chapter 1057 Section Chemical ReactionsIn your textbook, read about synthesis, combustion, decomposition, and that Q, T, X, and Z are symbols for elements.
