Consider the following unbalanced equation: Al(s) + O 2 (g) → Al 2 O 3 (s) b. Identify the type of reaction.

Hello. In this problem, we are asked to identify the type of the following unbalanced equation. Zinc metal reacting with oxygen gas to form zinc oxide. We are provided with four possible answers. Answer A states combination B, combustion C decomposition and D double displacement. We call that a combination reaction is where we have two or more substances combining to form a single substance. Combustion. We have a hydrocarbon compound. It could also be a compound that contains oxygen. It reacts with oxygen gas and we form carbon dioxide and water decomposition is the reverse of combination. So we have one substance that breaks down to form two or more simpler substances. And the last one double displacement, we have two compounds. We'll call them A B and CD that react then to form two new compounds C B plus ad and this is then the result of A and C exchanging places or replacing one another. Looking at the reaction we have provided we have two substances, zinc and oxygen combining to form a single substance. So this is a combination reaction which corresponds with answer. A thanks for watching. Hope. This helped

Textbook Question

Consider the following unbalanced equation:
Al(s) + O₂(g) → Al₂O₃(s)
b. Identify the type of reaction.

Verified step by step guidance

Step 1: Observe the given chemical equation: Al(s) + O₂(g) → Al₂O₃(s). This reaction involves aluminum (Al) reacting with oxygen (O₂) to form aluminum oxide (Al₂O₃).

Step 2: Recognize that this reaction involves a single product (Al₂O₃) being formed from two reactants (Al and O₂). This is a key characteristic of a synthesis reaction.

Step 3: Recall the definition of a synthesis reaction: A synthesis reaction occurs when two or more reactants combine to form a single product. This is also sometimes referred to as a combination reaction.

Step 4: Confirm that the reaction fits the criteria for a synthesis reaction because aluminum and oxygen are combining to form a single compound, aluminum oxide.

Step 5: Conclude that the type of reaction is a synthesis reaction (or combination reaction).

Key Concepts

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

Types of Chemical Reactions

Chemical reactions can be classified into several types, including synthesis, decomposition, single replacement, and double replacement. In a synthesis reaction, two or more reactants combine to form a single product. Understanding these categories helps in identifying the nature of the reaction based on the reactants and products involved.

Synthesis Reaction

A synthesis reaction, also known as a combination reaction, occurs when two or more substances combine to form a more complex product. In the given equation, aluminum (Al) and oxygen (O₂) react to form aluminum oxide (Al₂O₃), exemplifying a synthesis reaction where elements combine to create a compound.

Balancing Chemical Equations

Balancing chemical equations is essential to ensure that the law of conservation of mass is upheld, meaning the number of atoms of each element must be the same on both sides of the equation. Although the provided equation is unbalanced, recognizing the need for balance is crucial for accurately representing the reaction and understanding stoichiometry.
