Match each of the following physical and chemical properties with ethane, C 2 H 6 or sodium bromide, NaBr: b. burns vigorously in air

All right. Hi, everyone. So this question is asking us to determine whether the following property matches with cyclopropane C three H six or calcium bromide cabr two. And the property is that it is not flammable. Now, for this question, the problem itself can be simplified into a comparison between organic and inorganic compounds. Recall that an organic compound is one that contains carbon hydrogen and or carbon carbon bonds. Now, other atoms can be present in organic compounds. But if carbon hydrogen or carbon carbon bonds are not present, then the compound is considered to be inorganic. So when discussing whether or not a compound is flammable. In this case, we are discussing how quickly a material can catch fire or burn. Recall that flammability is a a property generally associated with organic compounds because organic compounds can react very easily with oxygen which therefore releases a very large amount of heat. This is why fuel mixtures are often composed of different organic molecules because when they catch fire, they release energy in the form of heat. So with this in mind, we can go ahead and compare cyclopropane versus calcium bromide. Now, considering the structure of cyclopropane the only atoms present in its structure are carbon and hydrogen. This means that cyclopropane is in fact an organic molecule. Now, on the other hand, calcium bromide cabr two contains neither carbon nor hydrogen. So because of this, it would be considered inorganic. So in this case, our task here was to identify which of the two compounds was not flammable, which means that of the two, the inorganic compound was more likely to match the description. Therefore, calcium bromide is expected to be or to not be ma. And so our answer here is going to be calcium bromide or Cabr two and there you have it. So with that being said, thank you so very much for watching and I hope you found this helpful.

Textbook Question

Match each of the following physical and chemical properties with ethane, C₂H₆ or sodium bromide, NaBr:
b. burns vigorously in air

Verified step by step guidance

Step 1: Understand the difference between physical and chemical properties. A chemical property describes a substance's ability to undergo a chemical change, such as burning or reacting with another substance. A physical property, on the other hand, can be observed without changing the substance's chemical identity.

Step 2: Analyze the property described in the problem: 'burns vigorously in air.' This refers to a substance's ability to react with oxygen in the air, which is a chemical reaction known as combustion.

Step 3: Recall the chemical nature of ethane (C₂H₆). Ethane is a hydrocarbon, and hydrocarbons are known to combust in the presence of oxygen, producing carbon dioxide and water. This makes 'burns vigorously in air' a chemical property of ethane.

Step 4: Consider sodium bromide (NaBr). Sodium bromide is an ionic compound and does not combust in air. It does not exhibit the property of burning vigorously in air.

Step 5: Conclude that the property 'burns vigorously in air' matches ethane (C₂H₆), as it is a chemical property associated with hydrocarbons like ethane.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Combustion

Combustion is a chemical reaction that occurs when a substance reacts rapidly with oxygen, producing heat and light. In the context of ethane (C₂H₆), it burns vigorously in air, releasing energy and forming carbon dioxide and water. This property is essential for understanding the reactivity of hydrocarbons and their use as fuels.

Physical Properties

Physical properties are characteristics of a substance that can be observed or measured without changing its chemical identity. These include state, color, melting point, and boiling point. Understanding these properties helps differentiate between substances like ethane and sodium bromide (NaBr), which have distinct physical characteristics.

Chemical Properties

Chemical properties describe how a substance interacts with other substances during a chemical reaction. For example, sodium bromide (NaBr) is an ionic compound that does not burn, while ethane (C₂H₆) is a hydrocarbon that combusts. Recognizing these properties is crucial for predicting the behavior of substances in various chemical contexts.
