Interpretation:
Substance does not react with oxygen at
Concept Introduction:
All kinds of matter are distinguished from one another based on their properties. This is used for description and identification of the matter. Two types of properties are there for matter and they are physical property and chemical property.
If a property of a matter is observed without changing the identity of the substance, then it is a physical property. Some of the common physical properties are melting point, boiling point, color etc. Physical state of the substance may change but not its chemical identity during determination of physical property.
Chemical property of a substance is the one that tells about the substance behavior to undergo or resist change in forming a new substance. Chemical property of a substance is the one that changes the identity of the substance.

Substance react explosively with oxygen at

- Describe how a homogeneous mixture differs from a heterogeneous mixture.arrow_forwardDescribe a piece of ice at the particulate level. Then describe what happens to the ice as it is heated until it melts and eventually boils.arrow_forwardThe following statements are best associated with the solid, liquid, or gaseous states of matter. Match the statements to the appropriate state of matter. a. This state is characterized by the lowest density of the three. b. This state is characterized by an indefinite shape and a high density. c. In this state, disruptive forces prevail over cohesive forces. d. In this state, cohesive forces are most dominant.arrow_forward
- Classify each of the following as aphysical or chemicalchange or property. A fireplace poker glows red when you heat it in the fire. A marshmallow turns black when toasted Loo long in a campfire. Hydrogen peroxide dental strips will make your teeth whiter. If you wash your jeans with chlorine bleach, they will fade. If you spill some nail polish remover on your skin, it will evaporate quickly. When making ice cream at home, salt is added Lo lower the temperature of the ice being used to freeze the mixture. A hair clog in your bathroom sink drain can be cleared with drain cleaner. The perfume your boyfriend gave you for your birthday smells like flowers. Mothballs pass directly into the gaseous state in your closet without first melting. A log of wood is chopped up with an axe into smaller pieces of wood. A log of wood is burned in a fireplace.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_forwardIdentify the following as either physical changes or chemical changes. (a) Diy ice (solid CO2) sublimes (converts directly from solid to gaseous CO2). (b) Mercury's density decreases as the temperature increases. (c) Energy is given off as heat when natural gas (mostly methane, CH4) burns. (d) NaCI dissolves in waterarrow_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. It reacts readily with an acid to produce gaseous carbon dioxide. (b) Gray, powdered zinc metal reacts with purple iodine to give a white compoundarrow_forwardIced Tea Use iced tea with and without ice cubes as examples to explain homogeneous and heterogeneous mixtures. If you allow all of the ice cubes to melt, what type of mixture remains?arrow_forwardWhat properties distinguish solids from liquids? Liquids from gases? Solids from gases?arrow_forward
- Questions 47 and 48: Samples of matter may be classified in several ways, including gas, liquid, or solid G, L, S; pure substance or mixture P, M; homogenous or heterogeneous Hom, Het; and, for pure substances, element or compound E, C. For each substance in the left column of the tables shown, place in the other columns the symbol from the top of the column that best describes the substance in its most common state at room temperature and pressure. Assume that the material is clean and uncontaminated. The first box is filled in as an example. G, L, S P, M Hom, Het E, C Factory smokestack emissions All, but mostly G Concrete in a sidewalk Helium Hummingbird feeder solution Table saltarrow_forwardQuestions 47 and 48: Samples of matter may be classified in several ways, including gas, liquid, or solid G, L, S; pure substance or mixture P, M; homogenous or heterogeneous Hom, Het; and, for pure substances, element or compound E, C.
