TYPES OF CHEMICAL REACTIONS

IDENTIFY THE TYPES OF CHANGE

CHEMICAL CHANGES LEADS TO CHEMICAL REACTIONS WE WILL OBSERVE DIFFERENT IMAGES AND TRY TO IDENTIFY THE TYPES OF CHEMICAL REACTIONS

WHAT D0 YOU OBSERVE

Synthesis Reactions: X + Y-->XY In this equation, X and Y can be compounds or elements. The result XY is a compound. Two different people unite to be one in marriage 2 Reactants and 1 Product

Examples of Combination Reactions: 2Ba + O2 -->2BaO 4Cu + O2 -->2Cu2O 2H2 + O2 -->2H2O 2Na + Cl2 -->2NaCl

What do you observe

Decomposition Reactions: In decomposition reaction, a compound is broken down into two simpler substances. XY --> X + Y Decomposition reactions are the opposite of synthesis reactions. 1 Reactant and 2 Products

Examples of Decomposition Reactions: 2HgO --> 2Hg + O2 2H2O --> 2H2 + O2 CaCO3 --> CaO + CO2
