How does the number of products in a synthesis reaction compare with the number of reactants?
A. The number of products is greater than the number of reactants.
B. The number of products is less than the number of reactants.
C. The number of products is the same as the number of reactants.
D. The number of products may be greater or less than the number of reactants.
Answer (3)
Synthesis reaction is defined as the reaction in which two or more substances combine in their elemental state to form a single compound.
The general equation representing this reaction follows:
A + B → A B
As, number of reactants in this type of reaction will always be more bacuse a single product is forming in this reaction.
Thus, the correct answer is Option B.
In a synthesis reaction, the number of products is typically less than or equal to the number of reactants. This is because a synthesis reaction involves combining elements or simpler compounds to form a more complex compound. As a result, the number of products will often be fewer because multiple reactants come together to form one product.
For example, when hydrogen gas react with oxygen gas, they form water:
2 H2 (g) + O2 (g) → 2 H2O (l)
In this case, two molecules of hydrogen and one molecule of oxygen (a total of three reactant molecules) combine to form two molecules of water. Hence, the correct answer is B) the number of products is less than the number of reactants.
However, remember that the number of atoms is conserved; they are simply rearranged from reactants to products. The number of molecules or compounds can differ before and after the reaction.
In a synthesis reaction, two or more reactants combine to form one product, resulting in the number of products being less than the number of reactants. Therefore, the correct answer is: B. The number of products is less than the number of reactants.
