bonds
Describe polarity
The uneven distribution of electrical charge within a molecule or bond creating a separation of charge with a positive and negative end
Differences between endo and exothermic
Exothermic releases energy and endothermic absorbs energy
Describe acids
Compound that produces hydronium ions H3O+ or H+
taste-sour
conduct-electricity corrosive
Describe the ph scale
A measurement system that measures the acidity/basicity of a solution
SO2+O+H2O=H2SO4
1,1,1,1
Describe covalent bonds
Atoms share electrons, form between nonmetals, poor electricity conductors
equation for double replacement
AB+CD=AD+CB
Describe a base
Any compound that increases the number of hydroxide ions when dissolved in water
Describe an acid/base reaction
A chemical reaction where a proton is transferred from an acid to a base
_HCI +_MnO2=_MnCL2+_H2O+_CL2
4,1,1,2,1
Describe ionic bonds
Transfer of electron form between metals and nonmetal, good electricity conductors
What are different ways to speed up reactions
Temperature, surface area, concentration
List the seven strong acids
Hydrochloric acid, hydrobromic acid, hydroiodic acid, nitric acid, perchloric acid, sulfuric acid, chloride acid
Explain fission
The splitting of a heavy atom’s nucleus into smaller particles
C9H12+O2=Co2+H2O
1,12,9,6
Definition of a bond
The force that holds atoms together as a unit
Equation for single replacement
AB+C=AC+B
Examples of acids and bases
Acids- lemon and vinegar
bases-soap and baking
Explain fusion
The joining of two lighter nuclei to form a heavier one
N2+H2=NH3
1,3,2
Definition of ionic bonds
A force that holds oppositely charged bonds together
What are the five types of reactions
Synthesis, decompisition, double replacement, single replacement, combustion
what is ph
A mesure of hedonism ion concentration of a solution
Explain radioactive decay
The spontaneous breakdown of an unstable atomic nucleus releasing energy and particles
Al + HCl → AlCl3 + H2
