Chemical Reactions Flashcards
What is a Chemical Reaction?
the molecules in the reactants interact to form new substances which forms a chemical reaction
How does a Conservation of Mass form?
fundamental concept of physics along with the conservation of energy and the conservation of momentum
What is an Observation that a chemical reaction has occurred ?
An Observation that there has been a chemical reaction is the color change or the foam that is formed.
What is the difference between a physical and a chemical reaction?
A physical reaction is different that a chemical reaction because a physical reaction you can’t see while a chemical reaction you can visualize.
Why does a temperature affect on a reaction speed?
A temperature has effect on the reaction because the tempurature is important in everything like a volcano explodes because of the pressure or heat.
What does precipitate mean?
Precipitate is evidence of a formation of not being able to dissolve
Definition of a Catlalyst
A catalyst is a substance that helps speed up the reaction.
What does Endothoric mean?
An Endothermic means when a chemical reaction decreases.
What is Exothermic?
Exothermic is when the chemical reaction increases.
What are Acids and Bases?
An Acid will usually be red,orange,or yellow while a base will be the darker colors like dark green,blue,or purple.
