Chemical Reactions Spring Break Flashcards
How many chemical reactions are there
infinite
What is one of the most common chemical reactions
Salts
What group is important for the creation of salt
Group 17
What do salts include
Metal atoms bonded to halogens or Metal atoms bonded to nitrate, phosphate, or sulfate ions
What are halogens
Salts bonded with any element from group 17 on the pte
What are halogens also referred to as
halides
What is an element very sensitive to light
Silver Oxide
What are salts formed from the reactions between metals and halogens called
halide salts
What is magnesium sulfate referred to as
epsom salt
What are salts formed from that is not a halogen
poly atomic Ions
What are two types of chemical reactions that always occur together
Oxidation and reduction
What are salts?
A compound formed when an acid and base react together and include metal which can be bonded to either a polyatomic ion or halogens
In a chemical equation, what does an acid always start with or have at the beginning
H
In a chemical equation, what does a base always have at the end of a chemical reaction
-OH
What does the reaction of hydrogen and oxygen produce
Pure water
What is the compound Fe2O3
Iron oxide
What do metals form with each other at an atomic level
ionic bonds
Do nonmetals form ionic bonds
no they form covalent bonds
What is the word for gaining electrons
reduction
LEO
Lose Electrons-Oxidize
GER
Gain Electrons-Reduce
Whenever one element is oxidized, another is reduced. What do scientists call this process
redox
What is verdigris
copper carbonate
What happens when a compound comes out of a solution
Precipitation, and after words it is called a precipitate
What does precipitating mean
to form a solid out of a chemical reaction
What is the chemical equation of lye
NaOH
When was Sodium Sulfate discovered
1625
What is Precipitation? NEW
A compound formed in an aqueous solution that is not solvable in water. A solid falls to the bottom of the solution and is an insoluble compound. 2 solutions combine to form an insoluble compound.
