Formation of one product from two or more reactants is known as

• A. Decomposition
• B. Combustion
• C. Synthesis
• D. Single-Replacement

Answer: (C)

When multiple starting substances come together to form a single product, that type of reaction is called a synthesis (or combination) reaction. The idea is building something more complex from simpler pieces. For example, hydrogen gas reacting with chlorine gas to form hydrogen chloride shows two reactants joining to make one product. Another common example is a metal reacting with oxygen to produce a metal oxide. The emphasis is on combining the starting materials into one new substance. Decomposition starts with one substance breaking into parts, combustion involves burning with oxygen to produce energy and usually more than one product like CO2 and H2O, and a single-replacement reaction involves one element trading places with another in a compound rather than simply forming one product from several reactants.
