Chemical Reactions 8.5E Investigate how evidence of chemical reactions indicates that new substances with different properties are formed.

1. What is matter? 2. What are the 3 states of matter? 3. Give one example each of an element, a compound, and a mixture. You will have about 5 minutes.

Chemical Reaction Notes. Matter is everything around you. Matter is anything made of atoms and molecules. Matter is anything that has a mass.

Evidence of Chemical Reactions Temperature Change Heat is absorbed by the substances causing the temperature to decrease Heat is released by the substances.

What is a property of matter? Characteristic of that type of matter Can be physical or chemical property Can be observed using your senses Cannot be observed.

–Chemical reactions occur when bonds between the outermost parts of atoms (valence electrons) are formed or broken.

Change When there is a change in matter there is a change in energy

Physical Change Predict the definition of physical change based on your knowledge of a physical property

Correct!!!!!!!! Physical change – a change in form or appearance of a substance without changing the identity Can be reversed

Examples of Physical changes Melting, boiling, freezing, evaporating, cutting into smaller pieces

Chemical change Predict the definition of a chemical change based on your knowledge of a chemical property

Correct Chemical change – a change that involves substances combining to form new substances with different properties Chemical bonds (force that holds atoms together) are rearranged= chemical reaction Difficult or impossible to reverse

Signs of a chemical reaction Fizzing, bubbling, change in color, heat or light is released Precipitate forms- solid forms

Examples of Chemical changes Rusting, burning, chemical reactions
