Chemical Reactions
This states that matter cannot be created nor destroyed during a chemical reaction
What is the Law of Conservation of Matter
This type of reaction involves simpler substances coming together to form a more complex molecule.
What is a synthesis reaction?
This is the type of bond formed between a metal and a non-metal.
What is an ionic bond.
These are the numbers in a chemical equation that indicate how many of each molecule are present in a chemical reaction.
What are coefficients?
These are the substances that are present before a chemical reaction takes place.
What are the reactants?
The process in which one or more substances is changed into a new substance or substances is called this.
What is a chemical reaction?
The rotting of fruits and vegetables is a great example of this type of reaction.
What is a decomposition reaction?
This is the definition of a covalent bond.
A bond that occurs when electrons are shared between atoms. Occurs between non-metals.
These are the numbers that indicate how many of each type of atom are present in a molecule?
What are subscripts?
This is produced as the result of a chemical reaction.
What is a product?
These are 3 different indicators of a chemical reaction.
What are color change, temperature change, bubbling, change in pH, etc...
Cu + FeCl2 ---> CuCl2 + Fe
is an example of this type of reaction.
What is a single displacement reaction?
What is the chemical formula for a molecule consisting of Na (Sodium) and O (Oxygen)?
NaO2
Balance the equation: H2 + O2 ---> H2O
2H2+O2 → 2H2O
This is the meaning of the arrow in a chemical equation.
What is "yields"?
This a reaction that absorbs more energy than it releases resulting in a decrease in temperature.
What is an endothermic reaction?
This type of reaction will increase in temperature as the reaction takes place.
What is an exothermic reaction?
In the Lewis Structure of H2O, which element will be put in the middle?
What is Oxygen?
Balance the equation: Fe + O2 → 2Fe2O3
4Fe+3O2 → 2Fe2O3
These are the diagrams we use to show the valence electrons of an atom.
What is a Lewis Dot Structure?
This is a solid that is formed from a reaction between two liquids.
What is a precipitate?
What is a double displacement reaction?
These are two properties of ionic compounds.
They have a high melting/ boiling point.
They conduct electricity when dissolved in water.
This is how you check to see if an equation is balanced.
What is count the number of atoms on both sides of the equation?
This is the term we use to describe an atom that has an unequal number of protons and electrons.
What is an ion?
