This video tutorial from Mumu Math and Science covers four types of chemical reactions: synthesis, decomposition, single replacement, and double replacement. Each reaction type is explained with general equations and examples. Synthesis reactions involve combining reactants to form a product, while decomposition reactions break down a reactant into products. Single replacement reactions occur when one element replaces another in a compound, and double replacement reactions involve the exchange of ions between two compounds. The video concludes with a reminder to practice kindness.

What type of chemical reaction involves two or more reactants combining to form a single product?

• Decomposition

• Double replacement
