A chemical property can be observed without changing the identity of the substance. A physical property is a characteristic that can be observed without changing the substance into another substance.
What is oxygen property?
Physical Properties of Oxygen The gas is colourless, odourless and insipid in a normal state. Liquid oxygen is slightly paramagnetic. It is reactive and forms oxides with every element except helium, neon, krypton, and argon. It is moderately soluble in water. Dioxygen is one of the common allotropes of oxygen.

Which statement describes a chemical property of water ? Under the proper conditions, water will breal apart into hydrogen and oxygen gas.
Which answer is an example of a chemical property?
Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion.
Which is a physical property of oxygen quizlet?
A physical property of oxygen is that it is a gas at room temperature. A chemical property of oxygen is that it reacts with iron to form rust.
Which of the following is a chemical property quizlet?
Chemical properties include flammability, reactivity, heat of combustion, and toxicity.
What is a chemical property quizlet?
Chemical Property Definition. A characteristic that can only be observed during a chemical reaction and involves changing the substance into another substance.
Is oxygen a reactive gas?
As you'll see in today's video by those crazy chemists at the University of Nottingham, oxygen is a highly reactive nonmetallic element that readily forms compounds with nearly all other elements. Many of these compounds are known as oxides. other) and is essential to most life.

Which of the following describes a chemical property of water quizlet?
Which of the following describes a chemical property of water? Water reacts violently with sodium metal. Meat spoils when it is not refrigerated. Which of the following describes a physical property of sucrose, more commonly known as table sugar?
What are types of chemical properties?
Here are some examples of chemical properties:
- Reactivity with other chemicals.
- Toxicity.
- Coordination number.
- Flammability.
- Enthalpy of formation.
- Heat of combustion.
- Oxidation states.
- Chemical stability.
Which statements describes a chemical change?
A chemical change happens when one chemical substance is transformed into one or more different substances, such as when iron becomes rust. Chemical changes occur through the process of chemical reactions, and the resulting substances have different properties because their atoms and molecules are arranged differently.
Which of the following is a chemical property ability to react with oxygen?
Flammability. Flammability is the ability of matter to burn. When matter burns, it combines with oxygen and changes to different substances.
Is the ability to react with oxygen a chemical property?
the ability of a substance to burn is chemical property that involves a substance reacting quickly with oxygen to produce light and heat. the process is called burning. the ability of a substance to rust is a chemical property that involves a substance reacting slowly with oxygen. the process is called rusting.
Which is an example of a chemical property quizlet?
What are examples of chemical properties? Some examples are flammability, reactions with acids, non-reactivity, etc.
Why is oxygen so reactive?
Oxygen's high reactivity is due to its biradical electron configuration. As shown in a molecular orbital drawing of O2, the two unpaired electrons make the molecule highly susceptible to bond formation. Oxygen has two allotropes (dioxygen, O2, and ozone, O3), both excellent oxidizing agents (Table P2).
Which of these characteristics are physical properties and which are chemical properties?
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.
Which describes a chemical property of copper?
All samples of a pure substance have the same chemical and physical properties. For example, pure copper is always a reddish-brown solid (a physical property) and always dissolves in dilute nitric acid to produce a blue solution and a brown gas (a chemical property).
What are 5 chemical properties?
Examples of chemical properties of a substance can include:
- Toxicity.
- Reactivity.
- Types of chemical bonds formed.
- Coordination number.
- Oxidation states.
- Flammability.
- Heat of combustion.
- Enthalpy of formation.
Which of the following is the best description of a chemical reaction?
Q. Which of the following is the best description of a chemical reaction? When molecules of a substance move slowly enough, they link together to form a crystalline structure.
Which of the following is a chemical change?
Growth of a plant, rusting of iron, cooking of food, digestion of food, and burning the candle are chemical changes because here is the chemical composition of the substance changes.
Does a chemical property react with oxygen?
1:054:08Reaction with Oxygen | Science for Grade 10 | Periwinkle – YouTubeYouTube
Is reaction with oxygen a chemical or physical property?
Chemical properties Chemical properties are simply the set of chemical changes that are possible for that substance. For the element magnesium (Mg), we could say that chemical properties include: the reaction with oxygen to form MgO. the reaction with hydrochloric acid to form MgCl2 and hydrogen gas (H2)
Is oxygen reacting physical or chemical?
chemical change Burning a sugar cube is a chemical change. Fire activates a chemical reaction between sugar and oxygen. The oxygen in the air reacts with the sugar and the chemical bonds are broken. Iron (Fe) rusts when it is exposed to oxygen gas in the air.
What chemical property is present in substances that react slowly to oxygen?
Answer and Explanation: The answer is choice a. The chemical property of a substance which pertains to its slow reactivity with oxygen gas defines its ability to rust.
Is the ability to react with oxygen is an example of a chemical property?
the ability of a substance to burn is chemical property that involves a substance reacting quickly with oxygen to produce light and heat. the process is called burning. the ability of a substance to rust is a chemical property that involves a substance reacting slowly with oxygen. the process is called rusting.
What is chemical property quizlet?
Chemical Property Definition. A characteristic that can only be observed during a chemical reaction and involves changing the substance into another substance.
What chemicals make up oxygen?
Natural oxygen is a mixture of three stable isotopes: oxygen-16 (99.759 percent), oxygen-17 (0.037 percent), and oxygen-18 (0.204 percent).
What is reaction with oxygen?
The reaction between oxygen and another element generally results in the formation of a binary compound known as an oxide. The reaction itself is known as oxidation. For example, the oxidation reaction between oxygen and sodium produces sodium oxide. In many cases, an element may form more than one oxide.
