What statement best describes an intensive property quizlet?
Which statement describes an intensive property of matter? It is the same for every sample of a single substance.
Which statement best describes a physical property?
Physical properties are observed by seeing how a substance reacts with other substances. Physical properties cause atoms and molecules to change structure when substances are mixed. Q. A physical property can be observed or measured without changing the identity of a substance.
Which of the following describes a physical property?
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.
What best describes a chemical property?
A chemical property describes the ability of a substance to undergo a specific chemical change. A chemical property of iron is that it is capable of combining with oxygen to form iron oxide, the chemical name of rust. The more general term for rusting and other similar processes is corrosion.
Which statement describes a physical property of oxygen?
The changes occurs in composition and identity of a substance. Oxygen can combine with a metal to produce a compound is a chemical property while rest of the options are shows physical properties. Therefore, the correct answer is (2).
What describes the chemical property of oxygen?
In normal conditions oxygen is a colourless, odourless and insipid gas; it condensates in a light blue liquid. Oxygen is part of a small group of gasses literally paramagnetic, and it’s the most paramagnetic of all. Liquid oxygen is also slightly paramagnetic.
Oxygen is odorless and colorless.
(1) Aluminum is malleable. (2) Aluminum reacts with sulfuric acid. (3) Aluminum conducts an electric current….Which statement describes a chemical property of aluminum?
Can ammonia be broken down by chemical means?
Potassium can’t be broken down by chemical change because it’s an element, which is the simplest form of matter. Sulfuric acid, ammonia and water are all compounds composed of elements. Compounds can be broken down into simpler compounds or elements by a chemical reaction.
Can ammonia be broken down by chemical change?
(1) Ammonia is composed of one nitrogen and three hydrogen atoms so it is a compound. Therefore it can be broken down by chemical change.
Which is a physical property of aluminum *?
Physical properties It has a melting point of 660°C (1,220°F) and a boiling point of 2,327-2,450°C (4,221-4,442°F). The density is 2.708 grams per cubic centimeter. Aluminum is both ductile and malleable. Ductile means capable of being pulled into thin wires.
What are three physical properties of aluminum foil?
Three physical properties of aluminum foil are that it is shiny (or reflective), it’s malleable, and it’s opaque.
What are 3 physical properties of aluminum?
The Physical Properties of Aluminum are as follows:
What are 5 physical properties of aluminum?
Aluminum ” Advantages and Properties of Aluminum
What are four physical properties of a piece of aluminum foil?
What are its Attributes?
Aluminium is a silvery-white, lightweight metal. It is soft and malleable. Aluminium is used in a huge variety of products including cans, foils, kitchen utensils, window frames, beer kegs and aeroplane parts. This is because of its particular properties.
The Physical properties of Carbon are the characteristics that can be observed without changing the substance into another substance. Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor.
What are 3 physical properties of carbon?
Chemical properties of carbon ” Health effects of carbon ” Environmental effects of carbon
What are three physical properties of carbon?
Carbon dioxide is the by product of combustion and metabolism. Physical Properties: Carbon is a soft, dull gray or black non-metal that you can scratch with a fingernail. Th density of carbon as graphite is 2.267 g/mL, which means it will sink in water.
What is the unique properties of carbon?
(a) The most unique property of carbon atom is its ability to combine itself, atom to atom to form long chains. This property of self combination is useful to us because it gives rise to an extremely large number of carbon compounds (or organic compounds). (b) A diamond crystal is a giant molecule of carbon atoms.
What are two carbon properties?
The two features of carbon that give rise to a large number of compounds are as follows: (i) Catenation: It is the ability to form bonds with other atoms of carbon. (ii) Tetravalency: With the valency of four, carbon is capable of bonding with four other atoms.
What are the four main properties of carbon?
What are the properties and uses of carbon?
Impure carbon in the form of charcoal (from wood) and coke (from coal) is used in metal smelting. It is particularly important in the iron and steel industries. Graphite is used in pencils, to make brushes in electric motors and in furnace linings. Activated charcoal is used for purification and filtration.
What are 3 uses of carbon?
Uses of Carbon Carbon (in the form of coal, which is mainly carbon) is used as a fuel. Graphite is used for pencil tips, high temperature crucibles, dry cells, electrodes and as a lubricant. Diamonds are used in jewelry and ” because they are so hard ” in industry for cutting, drilling, grinding, and polishing.
Uses of Carbon in daily life
Carbon dioxide appears as a colorless odorless gas at atmospheric temperatures and pressures. Relatively nontoxic and noncombustible. Heavier than air and may asphyxiate by the displacement of air. Soluble in water.
