Intro to Chemical Equations
A substance present at the start of reaction, always found on the Left side of the equation
What are reactants?
Small whole numbers that are placed in front of formulas in an equation in order to balance it
What are coefficients?
Human Activity
This reaction creates Carbon Dioxide and Water
What is Combustion?
The symbol (s) represents this state of matter
What is a solid?
A substance produced in a chemical reaction, always found on the Right side of the equation
What are products?
You have this when each side of the equation has the same number of atoms of each element and mass is conserved
What is a balanced equation?
Where does the CO2 end up when it is in the air?
The water
A + B ---> AB is this type of reaction
What is a combination or synthesis reaction?
Chemical Reaction that releases energy in the form of heat
What is a Exothermic Reaction?
In a chemical reaction the arrow sign --> represents this
What is yields or produces?
What coefficient is needed in front of Hydrogen to balance the following equation
H2 + O2 ---> 2 H2O
What is two (2)?
What happens to the pH of the water when CO2 is added.
It goes down.
AB + CD ---> AD + CB represents this type of reaction
What is a double replacement reaction?
What is a neutral pH?
What is 7?
This is used to separate reactants or products in a chemical reaction
What is a plus sign "+"?
The coefficient is needed in front of Oxygen to balance the following equation
4 Al + __ O2 ---> 2Al2O3
What is three (3)?
What is the name of the acid created in water that makes it acidic?
Carbonic Acid
AB ---> A + B represents this type of reaction
What is a decomposition reaction?
The number of total number of atoms in Sugar/ Glucose (C6H12O6)
What is 24?
How would heating up a chemical reaction change the reaction?
It would speed it up.
The coefficient needed in front of the Silver nitrate needed to balance the following equation
AgNO3 + Cu ---> Cu(NO3)2 + 2Ag
What is two (2)?
What rock can be added to the water to neutralize the pH?
What is limestone?
A + BC ---> B + AC is this type of chemical reaction
What is a single replacement reaction?
Around what pH would Drano be?
12-13
