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_forwardSuppose someone emptied ball bearings into a container of salt. Could you separate the ball bearings from the salt? How? Would your method involve no change, be a physical change, or be a chemical change?arrow_forward
- Decide whether each of the following is a physical property or a chemical property of the substance. a Salt substitute, potassium chloride, dissolves in water. b Seashells, calcium carbonate, fizz when immersed in vinegar. c The gas hydrogen sulfide smells like rotten eggs. d Fine steel wool (Fe) can be burned in air. e Pure water freezes at 0C.arrow_forwardOn October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size. (Density of Cu = 8.96 g/cm3; density of Zn = 7.14 g/cm3).arrow_forwardClassify each of the following as (1) a physical property, (2) a physical change, (3) a chemical property, or (4) a chemical change. a. the process of burning a piece of newspaper b. the fact that metallic copper reacts with chlorine gas c. the process of melting ice d. the fact that metallic gold is a solid at room temperaturearrow_forward
- Which part of the description of a compound or element refers to its physical properties and which to its chemical properties? (a) Calcium carbonate is a white solid with a density of 2.71 g/cm3.

Did the student draw a correct representation of the reaction? If not, what was the error the student made?arrow_forwardIn the accompanying photo, you see a crystal of the mineral calcite surrounded by piles of calcium and carbon, two of the elements that combine to make the mineral. (The other element combined in calcite is oxygen.) Based on the photo, describe some of the physical properties of the elements and the mineral. Are any properties the same? Are any properties different? Calcite (the transparent, cube-like crystal) and two of its constituent elements, calcium (chips) and carbon (black grains). The calcium chips are covered with a thin film of calcium oxide.arrow_forward
