To further understand acid-base reaction, you can check the Acid-Base Solutions simulation by <a href="https://phet.colorado.edu/en/simulation/acid-base-solutions">phet.colorado.edu</a>

Acid-Base Solutions

1. Combination Reaction (Synthesis) 2. Decomposition Reaction 3. Single Displacement/Replacement 4. Double Displacement (Metathesis) 5. Combustion (Burning) 6. Acid-Base Reaction(special double displacement)

Using the data from Activity 2 "What's in a Reaction," classify the chemical reactions. Use the Guide Card on page 412 (LMs) to answer this activity and then answer the guide questions.

Types of Chemical Reactions

Chemical Reactions

Direction: Classify the following unbalanced chemical equations according to the six types of chemical reactions.

A. Combination B. Decomposition C. Single displacement D. Double displacement E. Combustion F. Acid-base

Answer the enrichment activity from your Gr. 10 LMs page: 414

This is a special kind of double displacement that takes place when an acid and base react with each other that involves the exchange of one or more hydrogen ions (H+) between species that may be neutral (molecules, such as water or electrically charged ions, such as ammonium (NH4+) or  hydroxide (OH−)

8. Which chemical equation correctly represents the decomposition reaction that takes place when ammonia breaks down to form hydrogen gas and nitrogen gas?

A. B. C. D.

One compound breaks down into two or more simpler compounds or elements (opposite of formation reactions)

<a href="https://www.sciencedirect.com/topics/earth-and-planetary-sciences/electrolysis">Electrolysis</a>

This is when one element replaces another element from a compound. The more active element takes the place of the less active element in a compound.

1. Double Displacement 2. Combustion 3. Single Displacement 4. Double Displacement 5. Acid- Base / Double Displacement 6. Combination 7. Decomposition 8. Combustion 9. Acid- Base 10. Double Displacement

2. Which of the following are decomposition reactions?

A. 1 and 4 B. 4 only C. 2 and 3 D. All are decomposition reactions

Also known as hydrocarbon combustion. This when oxygen combines with a hydrocarbon (i.e. oil, fuel, natural gas) to form water, carbon dioxide, and heat.

By the name itself, can you tell which type of chemical reaction is being represented by the  following symbol-equations?

Let's answer the activity!

4. In the following chemical reaction, what product is represented by&nbsp;X? AlCl3&nbsp;&nbsp;+&nbsp;NaOH&nbsp;→&nbsp;&nbsp;X&nbsp;+&nbsp;NaCl

Direction: Choose the best letter answer in each item.

4. Double Displacement (<a href="https://www.nature.com/subjects/metathesis-reactions">Metathesis</a>)

This is when the positive ions (cations) and negative ions (anions) of different compounds switch places, forming two entirely different compounds.
