Regents Chemistry Exam June 2025 Question 47
Given the particle-diagram equation:
Which type of reaction is represented by the equation?
Which type of reaction is represented by the equation?
(1) synthesis (3) single replacement (2) decomposition (4) double replacement
Solution:
The particle diagram shows atoms of one element coming together with atoms of another element to form a new compound. This type of reaction is called synthesis. Choice 1 is the correct answer choice.
Types of Chemical Reactions:
Synthesis = two or more reactants come together to form one product A+B--> AB
Decomposition = opposite of synthesis, one reactant breaks into multiple products.
AB --> A+B
Single Replacement= one element replaces another element that is a part of a compound A +BC --> AC +B
Double Replacement = two elements in two compounds replace one another. Think of two dancing couples switching partners. AB +CD --> AD +CB
