Chemical Equations
This rule of the universe that requires us to balance equations.
What is the Law of Conservation of Mass?
Often associated with fire and explosions, this type of reaction produces CO2 and H2O.
What is combustion?
Which is NOT a characteristic of a covalent chemical bond?
A. lower heat of fusion and heat of vaporization
B. occurs between nonmetal and nonmetal
C. do not exhibit any electrical conductivity
D. do not exhibit any electrical conductivity
C. do not exhibit any electrical conductivity
This equation below is this type of reaction chemical reaction:
H2O2 + heated ----> H2(g) + O2.
What is decomposition?
This type of chemical bond only forms crystalline solids and when dissolved in water these compounds make an electrically conductive solution.
Ionic Bond
These are numbers put in front of compounds to balance chemical equations.
What are coefficients?
A reaction where two or more substances combine to form a single product.
What is synthesis?
A symbolic representation of a chemical reaction using words or chemical formulas.
What is a chemical equation?
The equation shown below is an example of this type of reaction:
CaSO4 + 2K ---> K2SO4 + Ca
What is a single replacement reaction?
This is the formula for baking soda.
How many total atoms are found in this compound?
NaHCO3
six
These substances are created from a chemical reaction.
What are products?
A reaction where a more reactive element changes places with a less reactive element in a compound.
What is single replacement reaction?
These elements that can only exist in a two atom molecule if not in a compound.
What are diatomic molecules?
The equation shown below is this type of chemical reaction:
2Na + Cl2 ---> 2NaCl
What is a synthesis or combination reaction?
Does this chemical reaction follow the Law of Conservation of Mass?
Mg(NO3)2 + Li → Mg + LiNO3
No, this equation does not follow the LOC because the nitrogen and oxygen are not balanced.
These starting substances of a chemical equation are found on the left side of the arrow.
What are reactants?
A reaction where one substance breaks down into two or more products.
What is decomposition?
At the end of chemical reactions, what is the total mass of the reactants compared to the total mass of the products?
They are the same.
The equation shown below is this type of chemical reaction:
CH4 + 2O2 ---> CO2 + 2H2O
What is combustion?
Balance this equation.
TiBr4 + H2O → TiO2 + HBr
TiBr4 + 2H2O → TiO2 + 4HBr
These numbers used to designate the number of atoms or molecules in an element or compound.
What are subscripts?
This reaction occurs when two elements in different compounds change places with each other to form two new compounds.
What is double replacement?
This type of chemical reaction is represented by the following pattern:
A + BC ---> B + AC
What is a single replacement reaction?
The equation show below is an example of this type of chemical reaction:
ZnI2 + AlBr3 ---> ZnBr2 + AlI3
What is a double replacement reaction?
Balance this equation and name the type of chemical reaction.
C6H12O6 + O2 → CO2 + H2O
C6H12O6 + 6O2 → 6CO2 + 6H2O
Combustion
