Question
Answer
Chemical Property   Characteristics that gives a substance the ability to undergo a change that results in a new substance.  
🗑
Chemical Change   Changes in the identity of a substance due to its chemical properties/ not reversible; only sometimes/ rate of reaction influenced by temp, concentration and exposed surface.  
🗑
Slow Oxidation   Occurs at ordinary temp/ produces no light/ no noticeable heat.  
🗑
Fast Oxidation   Occurs rapidly/ burning of a materiel/ produces light/ noticeable heat.  
🗑
Food Spoilage   Oxidation process or enzyme action/ meat and fruit enzymes breakdown tissues unless inactivated (stopped)/ oxidation is caused by the oxygen in the air.  
🗑
Energy   Released or absorb during a chemical reaction.  
🗑
Endothermic Reaction   Absorb heat energy.  
🗑
Exothermic Reaction   Releases heat energy.  
🗑
Inhibitor   Slows down a chemical reaction.  
🗑
Catalyst   Speeds up a chemical reaction  
🗑
Activation Energy   Energy need to get a reaction started.  
🗑
Law of Conservation of Mass   By Antoine Lawoisier/ matter cannot be created nor destroyed.  
🗑
PH Scale   Power of Hydrogen or potential Hydrogen/ determines the acidity or base of a solution/ PH scale ranges from 0-14 Acid=0- 6.9 Neutral=7 Base= 7.1- 14  
🗑
Indicator   Substance that changes color at different PH levels.  
🗑
Acids   0-6.9/ sour taste/ often corrosive/ conduct electricity(electrolyte)/ used in pickling (removes impurities from metals)/ neutralizes base/ turns blue litmus paper red or pink/ reacts with some metals to produce hydrogen gas/ produces H+ ions.  
🗑
More for Acids   most acids have formulas that start with H/ Form hydroponic ions (H30+) when dissolved in water.  
🗑
Base   7.1-14/ bitter taste/often corrosive/ conduct electricity/ feels slippery and slimy/neutralized acid/ turns red limtus paper blue/ produces OH- ions/ Produces hydroxide ions when bases mix with water./many bases formulas end in OH.  
🗑
Neutralization Reaction   Both substance lose their distinctive properties/ a salt and water are created/ a salt is an ionic compound that forms when a metal ion replaces the hydrogen ion of an acid  
🗑
   
🗑
