Secrets of Chem
A substance present at the start of reaction, always found on the Left side of the equation
What are reactants?
Color change, emission of energy (like heat or light), and a change in odor are all signs of
What are signs of chemical reactions
A chemical change in which two or more substances react to form in a single new substance
What is a combination or synthesis reaction?
This reaction creates Carbon Dioxide and Water
What is Combustion?
The three most common states of matter?
What are solids, liquids, and gasses
A substance produced in a chemical reaction, always found on the Right side of the equation
What are products?
The 5 different types of chemical reactions
What are synthesis, single replacement, double replacement, decomposition, and combustion
A chemical change in which one element replaces a second element in a compound.
What is a single replacement reaction?
A + B ---> AB is this type of reaction
What is a combination or synthesis reaction?
Quantitative vs qualitative
Qualitative includes variables with desciptions
In a chemical reaction the arrow sign --> represents this
What is yields or produces?
Classify the following reaction and explain your reasoning:
H2 + O2 → H2O
What is synthesis
A chemical change involving an exchange of positive ions between two compounds
What is a double replacement reaction?
AB + CD ---> AD + CB represents this type of reaction
What is a double replacement reaction?
Element, Compound, or Mixture
Table Salt
Compound
NaCl
This is used to separate reactants or products in a chemical reaction
What is a plus sign "+"?
Why do we use the word decomposition to describe this type of reaction?
AB --> A + B
Decomposition means to break down or break apart
A chemical change in which a single compound breaks down into two or more simpler products
What is a decomposition reaction?
AB ---> A + B represents this type of reaction
What is a decomposition reaction?
What are oxygen and glucose
All 5 signs a chemical reaction has occurred
Color change, odor change, gas production, precipitate formation, and emission of energy
Always a product in a combustion reaction
A chemical change in which an element or compound reacts with oxygen
What is combustion?
A + BC ---> B + AC is this type of chemical reaction
What is a single replacement reaction?
What type of chemical reaction is photosynthesis?
CO2 + H2O --> C6H12O6 + O2
Synthesis Reaction
