TEST Flashcards
Chemical reaction types
Synthesis Decomposition Single displacement Double displacement Combustion
reactants and products
Reactants ➡️ products
Acid
H
Base
OH
Acid vs base
Acid right base left
Endothermic
Take in more energy to break bonds
Exothermic
Give out more energy to make bonds
Law do conservation of energy
Energy cannot be created or destroyed it can only change forms
Physical properties
Can be observed without changing the identity of the substance
Physical property example
Multipoint viscosity density solubility hardness Luster malleability ductility
Physical change
They usually reversible change in the physical property of a substance change and state or phase
Chemical properties
Characteristic that’s observed during a reaction and identity/chemical composition of the substance changes
Chemical property example
Flammability pH reactivity and toxicity
Chemical change
And irreversible on chemical reaction involving the rearrangement of atoms and a change in their chemical properties
Chemical change examples
Burning digesting cooking rust
Signs of the chemical reaction
Color change precipitation (solid forming from liquid) gas temperature change
Catalyst
Substance that increases the rate of a chemical reaction
Inhibitor
The substance that slows the prohibits a chemical reaction
Block entrance
Interact with catalyst to prevent from working
Equilibrium
A chemical reaction in which the forward and reverse reactions occur at equal rights
