What are three chemical changes you encounter on a daily, weekly, or monthly basis?
Imagine what life would be like without these types of changes occurring around us all the time. What aspects of life would be significantly harder? Would any aspects of life be easier? Why are these changes essential to our daily life?
There are four sketches below. The first sketch shows a sample of Substance X. The three sketches underneath it show three different changes to the sample. You must decide whether each of these changes is possible. If a change is possible, you must also decide whether it is a physical change or a chemical change.
Which of the following are chemical changes?
mold
Distillation of Salt Water
Cutting Fabric
Digestion
rust
sorting coins

- Classify each statement as an observation, a law, or a theory. In chemical reactions, matter is neither created nor destroyed.arrow_forwardSugar is a compound made of the elements carbon, hydrogen, and oxygen. If you add sugar to water, you make a mixture. How is a compound different from a mixture? Use the example to help you explain your answer. *DO NOT use the chemical versus physical distinction in your explanation*arrow_forwardExamine the equations in the first column. Name two things the have in common.arrow_forward
- With explanation of why the chosen answer is wrong and why the new one is correct! Thank you.arrow_forwardParticles in the illustration below undergo a chemical change. Which among the remaining boxes, a through d, can represent the products of the chemical change? If a box cannot represent the products of the chemical change, explain why. a b c darrow_forwardClassify each of the following changes as physical or chemical. a. A newspaper page turns yellow over time. b. A rubber band breaks. c. A firecracker explodes. d. Dry ice disappears over time.arrow_forward
- Confronted with the box shown in the diagram, you wish to discover something about its internal workings. You have no tools and cannot open the box. You pull on rope B, and it moves rather freely. When you pull on rope A, rope C appears to be pulled slightly into the box. When you pull on rope C, rope A almost disappears into the box. a. Based on these observations, construct a model for the interior mechanism of the box. b. What further experiments could you do to refine your model?arrow_forwardAlthough reviewing your lecture notes and reading your text book are important, why does the study of chemistry depend so much on problem solving? Can you learn to solve problems yourself just by looking at the solved examples in your textbook or study guide? Discuss.arrow_forwardIn each case, describe the change as a chemical or physical change. Give a reason for your choice. Salt dissolves when you add it to water. Food is digested and metabolized in your body. Crystalline sugar is ground into a fine powder. When potassium is added to water there is a purplishpink flame and the water becomes basic (alkaline).arrow_forward
- In each case, decide if the change is a chemical or physical change. (a) A cup of household bleach changes the color of your favorite T-shirt from purple to pink. (b) Water vapor in your exhaled breath condenses in the air on a cold day. (c) Plants use carbon dioxide from the air to make sugar. (d) Butter melts when placed in the Sun.arrow_forwardStudents approaching the study of chemistry must learn certain basic facts (such as the names and symbols of the most common elements), but it is much more important that they learn to think critically and to go beyond the specific examples discussed in class or in the textbook. Explain how learning to do this might be helpful in any career, even one far removed from chemistry.arrow_forwardWhich of the following represent physical properties or changes, and which represent chemical properties or changes? You curl your hair with a curling iron. You curl your hair by getting a “permanent wave” at the hair salon. Ice on your sidewalk melts when you put salt on it. A glass of water evaporates overnight when it is left on the bedside table. Your steak chars if the skillet is too hot. Alcohol feels cool when it is spilled on the skin. Alcohol ignites when a flame is brought near it. Baking powder causes biscuits to rise.arrow_forward
