Chemistry
100
This is the only part of atom that make up chemical bonds.
What are electrons?
100
This is what is created or results in chemical reaction.
What is a product?
100
This substance has a bitter taste and a slippery feel.
What is a base?
100
This is the value used to express how acidic or basic a solution is.
What is the pH scale?
100
For a chemical bond to break, this is required.
What is energy?
200
This is a type of bond where electrons are transferred.
What is an ionic bond?
200
This is a type of reaction that in which heat is released into the surroundings.
What is an exothermic reaction?
200
This is a reaction in which two or more substances combine to form one new compound.
What is a synthesis reaction?
200
This is the initial boost of energy required to start a chemical reaction.
What is activation energy?
200
This is a compound that can change color depending on the pH scale of the solution.
What is an indicator?
300
This is a type of bond where atoms share one or more pairs of electrons.
What is a covalent bond?
300
These are the four factors that affect reaction rates.
What are temperature, surface area, concentration, and the presence of an inhibitor or a catalyst?
300
This is a reaction in which a single compound breaks down to form two or more substances.
What is a decomposition reaction?
300
These are the starting materials in a chemical reaction.
What are the reactants?
300
This uses chemical symbols and formulas as a shortcut to describe a chemical reaction.
What is a chemical equation?
400
This is a type of bond formed by the positively charged metal ions and the electrons around them.
What is a metallic bond?
400
This lowers the activation energy.
What is a catalyst?
400
When and acid and a base neutralize each other, this is what remains.
What are water and salt?
400
This is an ionic compound formed from the positive ion of a base and the negative ion of an acid.
What is salt?
400
This is a reaction in which one element takes the place of another element in a compound.
What is a single-displacement reaction?
500
This is the electron in the outermost energy level of an atom.
What is a valence electron?
500
This is why mass can neither be created or destroyed in a normal chemical reaction.
What is The Law of Conservation of Mass?
500
Brittleness and high melting points are properties of this.
What is an ionic compound?
500
A reaction in which a gas, solid, precipitate, or molecular compound forms from the exchange of ions between two compounds.
What is a double-displacement reaction?
500
This is the smallest particle into which a covalently bonded compound can be divided and still be the same compound.
What is a molecule?
