What particle is transferred from one atom to another in a redox reaction?
200
The new substance formed as result of that change.
What is a product?
200
A reaction in which two reactants combine into one product.
What is a synthesis reaction?
200
A chemical reaction that releases energy to its surroundings.
What is a exothermic reaction?
200
The rate at which reactants change into products over time
What is a reaction rate
200
Increases reaction rate
In general, an increase in temperature will what?
300
Numbers that appear before a formula in a chemical equation to show the relative proportions of reactants and a product
What are coefficients?
300
A reaction in which two elements switches or exchange and create two different compounds.
What is a double replacement reaction?
300
A chemical reaction that absorbs energy from its surroundings.
What is a endothermic reaction?
300
A substance that affects the reaction rate without being used up in a reaction
What is a catalysts
300
Is a reaction in which the conversion of reactants into products and the conversion of products into reactants can happen simultaneoulsy
What is a reversible reaction?
400
Mass is neither created nor destroyed
What dies the conservation of mass states?
400
A reaction in which one reactant break down into two products?
What is a decomposition reaction?
400
The total amount of energy before and after the reaction are the same.
What does the conservation of energy states?
400
Any change that happens over a period of time
What is a rate
400
Is a state in which the forward and reverse paths of a change that take place at the same rate
What is equilibrium?
