Introductory Chemistry: An Active Learning Approach is a comprehensive textbook that methodically guides students through the fundamental concepts of chemistry while emphasizing active, hands-on learning strategies. The book begins with basic principles and historical experiments—such as Lavoisier’s work on combustion—before moving into detailed explorations of matter, energy, and precise measurement techniques. It systematically covers a wide spectrum of topics including gas laws, atomic theories (both nuclear and quantum models), chemical reactions, bonding, and the intricacies of organic and biochemistry. By blending scientific principles with practical applications and problem?solving methods, this book equips learners with the analytical tools necessary to understand and apply chemistry in both laboratory and real-world contexts.

Problem 1
Identify the following samples of matter as macroscopic, microscopic, or particulate: (a) a human skin cell; (b) a sugar molecule; (c) a blade of grass; (d) a helium atom; (e) a single-celled plant too small to be seen with the unaided eye.

Problem 2
Consider the following particulate-level representation of a chemical equation: CAN'T COPY THE FIGURE The white spheres represent hydrogen atoms, the black sphere represents a carbon atom, and the red spheres represent oxygen atoms. (a) Write a balanced chemical equation representing this reaction. (b) Write a word description of the reaction on the particulate and molar levels.

Problem 3
When hvdrogen sulfide reacts with oxygen, water and sulfur dioxide are produced. The balanced equation for this reaction is $2 \mathrm{H}_{2} \mathrm{S}(\mathrm{g})+3 \mathrm{O}_{2}(\mathrm{g}) \rightarrow 2 \mathrm{H}_{2} \mathrm{O}(\ell)+2 \mathrm{SO}_{2}(\mathrm{g}) .$ For all parts of this question, consider what will happen if 4 moles of hydrogen sulfide react. a) How many moles of oxygen are consumed? b) How many moles of water are produced? c) How many moles of sulfur dioxide are produced?

Problem 4
Mixtures of gases are always true solutions. True or false? Explain why.
Problem 5
The first step in the Ostwald process for manufacturing nitric acid is the reaction between ammonia and oxygen described by the equation $4 \mathrm{NH}_{3}+5 \mathrm{O}_{2} \rightarrow 4 \mathrm{NO}+6 \mathrm{H}_{2} \mathrm{O} .$ Use this equation to answer all parts of this question. a) How many moles of ammonia will react with 95.3 moles of oxygen? b) How many moles of nitrogen monoxide will result from the reaction of 2.89 moles of ammonia? c) If 3.35 moles of water is produced, how many moles of nitro- gen monoxide will also be produced?
Problem 6
Every pure substance has a definite and fixed set of physical and chemical properties. A solution is prepared by dissolving one pure substance in another. Is it reasonable to expect that the solution will also have a definite and fixed set of properties that are different from the properties of either component? Explain your answer.
