Flashcards in Chemical Change Deck (27):
A property you can observe with your five senses
A material property that can be observed while the material is or has gone through a chemical reaction
The process in which a Solid changes to a liquid
The process in which a liquid changes into a gas
The process in which a liquid solidifies thus making it a solid
The process of a liquid solidifying from warm and cold temperature instead of just cold
The process in which gas cools and changes back into a liquid
The process in which a solid changes into gas without turning into a liquid first e.g. dry ice
The process in which a Gas cools into solid without the added step of changing into a liquid first e.g. Carbon Dioxide
A state of matter in which particles are very close together and when heated vibrate e.g. ice
A state of matter in which particles are more spread and move a liquid always takes the shape of the container it is in e.g. water
A state of matter in which particles are the furthest apart from each other the particles spread out into space. e.g. Steam.
a chemical change in which one or more new chemical substances are produced
chemical substance used up in a chemical reaction. Some chemical bonds in a reactant are broken during the reaction.
new chemical substance that results from a chemical reaction
solid product of a chemical reaction that does not dissolve in water
The speed in which a reaction occurs
chemical that helps to start or speed up a chemical reaction.
The corrosion of iron from water and oxygen
a chemical reaction that wears away a metal. Air, water or chemicals in air and water, as well as many household substances, can be corrosive. Many acids and other corrosive substances are dangerous.
A reddish brown substance formed when iron reacts with oxygen and water
coating over a metal surface to prevent it from corroding.
protecting a metal by covering it with a more reactive metal that will corrode first
combining a substance with oxygen in a flame
chemical reaction involving the loss of electrons by a substance
substance, such as coal, oil and natural gas, that has formed from the remains of ancient organisms. Coal, oil and natural gas are often used as fuels; that is, they are burnt in order to produce heat.
