synthesis
decomposition
oxidation
replacement
Answer (1)
The reaction A B + C Dr i g h t a rro w A D + CB involves two compounds exchanging ions.
This type of reaction is a double replacement reaction.
Among the given options, 'replacement' best describes this reaction.
Therefore, the answer is replacement.
Explanation
Understanding the Reaction Formula The general formula for a chemical reaction is given as A B + C Dr i g h t a rro w A D + CB . We need to identify the type of reaction that corresponds to this general formula from the given options: synthesis, decomposition, oxidation, and replacement.
Identifying the Reaction Type In the given reaction, two compounds, A B and C D , react to form two new compounds, A D and CB . Notice that the cations A and C switch anions. This type of reaction is known as a double replacement reaction, where two reactants exchange ions to form two new compounds.
Matching with the Given Options Comparing the identified reaction type (double replacement) with the given options, we find that 'replacement' is the closest match. While 'double replacement' is more accurate, 'replacement' is the term provided in the options.
Conclusion Therefore, the type of reaction that has the general formula of A B + C Dr i g h t a rro w A D + CB is a replacement reaction.
Examples
Consider baking a cake where you mix baking soda ( N a H C O 3 ) with vinegar ( C H 3 COO H ). This results in carbon dioxide ( C O 2 ), which makes the cake fluffy, along with sodium acetate ( C H 3 COON a ). This is a double replacement reaction, similar to the general formula A B + C Dr i g h t a rro w A D + CB , where the ions switch partners to form new compounds. Understanding such reactions helps in various applications, from cooking to industrial processes, by predicting the outcomes of mixing different substances.
