Concept explainers
Interpretation:
To describe whether paper torned into several pieces is a physical change or not.
Concept Introduction:
In the physical property, the material or substance will not change its chemical identity only changes its physical state like solid into liquid or liquid into gas. For example changing in physical state like ice melts into water.
In the chemical property, the material or substance will change its chemical identity means there is a new substance formed by the formation heat, energy or gas. Like sodium readily reacts with water and farms another compound.
In the chemical change substance lose the identity while in the physical change substance does not lose the identity.
Interpretation:
To describe whether mixing of two clear solutions to produce a yellow solid is a physical change or not.

Interpretation:
To describe whether burning of match in air is a physical change or not.

- Classify 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_forwardWhich among the following are physical changes? a blowing glass; b fermenting grapes; c forming a snowflake; d evaporating dry ice; e decomposing a substance by heating it.arrow_forwardIn each case, identify the italicized property as a physical or chemical property. Give a reason for your choice. The normal color of the element bromine is red-orange. Iron is transformed into rust in the presence of air and water. Dynamite can explode. Aluminum metal, the shiny “foil” you use in the kitchen, melts at 660 °C.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_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 decomposing hydrogen peroxide b. the fact that a block of ice can be chipped into smaller pieces c. the process of evaporating a liquid d. the fact that water freezes at 32Farrow_forwardIn each case, describe the change as a chemical or physical change. Give a reason for your choice. (a) A cup of household bleach changes the color of your favorite T-shirt from purple to pink. (b) The fuels in the space shuttle (hydrogen and oxygen) combine to give water and provide the energy to lift the shuttle into space. (c) An ice cube in your glass of lemonade melts.arrow_forward
- Which of the following are chemical changes? Which are physical changes? a. the cutting of food b. interaction of food with saliva and digestive enzymes c. proteins being broken down into amino acids d. complex sugars being broken down into simple sugars e. making maple syrup by heating maple sap to remove water through evaporation f. DNA unwindingarrow_forwardClassify each of the following as a physical or chemical change, and give at least one observation, fact, or reason to support your answer. a. A stick is broken into two pieces. b. A candle burns. c. Rock salt is crushed by a hammer. d. Tree leaves change color in autumn.arrow_forwardThe following are properties of substances. Decide whether each is a physical property or a chemical property. a Chlorine gas liquefies at 35C under normal pressure. b Hydrogen burns in chlorine gas. c Bromine melts at 7.2C. d Lithium is a soft, silvery-colored metal. e Iron rusts in an atmosphere of moist air.arrow_forward
- In 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_forwardDuring a very cold winter, the temperature may remain below freezing for extended periods. However, fallen snow can still disappear, even though it cannot melt. This is possible because a solid can vaporize directly, without passing through the liquid state. Is this process (sublimation) a physical or a chemical change?arrow_forwardWhich of these is a chemical property? Ice melts at 0 degrees C. Helium is very non-reactive Water has a high specific heat.Sodium is a soft shiny metal Glycerol is a viscous liquid.arrow_forward
