Chemistry

We can balance the equation because of….

• Ionic bond

• Law of conservation mass

• Stoichiochemistry

Substance that are destroyed by the chemical change ( bonds break )

• Product

• Reactant

• Proton

• Electron

Substance created by the chemical change ( new bond form)

• Product

• Reactant

• Proton

• Electron

It produces new substances

• Chemical Reaction

• Evidence of Chemical Reaction

• Chemical Equation

• Reactants

Describe chemical reactions

• Chemical Reaction

• Evidence of Chemical Reaction

• Chemical Equation

• Reactants

Evidence for a chemical reaction

• Evolution of light or heat

• Temperature Change

• Formation of bubble, precipitate

• Color change due to the new substance

• Freezing

Two or more simple substance combine to form a more complex structure

• Synthesis

• Decomposition

• Single Replacement

• Double Replacement

• Combustion

More complex substances breaks into two or more simple parts

• Synthesis

• Decomposition

• Single Replacement

• Double Replacement

• Combustion

a single uncombined element replaces another element in an ionic compound based on its reactivity

• Synthesis

• Decomposition

• Single Replacement

• Double Replacement

• Combustion

Predict the product of single replacement reactions K+ Na2SO4 —->

• NaK + SO4

• Na + K2SO4

• Na + SO4

• K + Na
