Question

The table compares the type of reactants and products taking part in two chemical changes. Chemical Change Comparison Chemical Reaction Reactants Products X an element and a compound a compound Y an element and another element a compound Which of the following statements correctly identifies the synthesis reaction and explains why? (5 points) Only chemical reaction X, because one reactant is a compound Only chemical reaction Y, because both reactants are elements Neither chemical reaction X nor Y, because they have only one product Both chemical reactions X and Y, because there are two reactants and a single produc

Answer 1

Both chemical reactions X and Y are synthesis reactions because they involve the combination of two reactants to form a single product. Here option D is correct.

In a synthesis reaction, two or more substances combine to form a single product. Both chemical reactions X and Y fit this description:

In reaction X, an element (single substance) and a compound (combination of elements) react to form a compound (single substance).

In reaction Y, two elements (two single substances) react to form a compound (single substance).

Synthesis reactions typically involve the combination of substances to create a more complex product. In both cases, there are two reactants coming together to form a single product, making them synthesis reactions. Here option D is correct.
