Type o reaction in which heat energy is released by forming the chemical bonds in the product.
Exothermic
What evidences suggest a chemical reaction has taken place? (Two)
Color Change; Gas Released; Smells; Precipitate Forms; Temperature Change
Type of reaction, which requires more energy to be supplied than it releases. (Absorb heat energy)
Endothermic
True or False? Phase change is an evidence of a chemical reaction.
False
True or False? Many chemical reactions require energy or release it. This causes the temperature to decrease or increase
True
True or False? During a chemical reaction, no atoms are lost and no new atoms are produced.
True
True or False? During a chemical reactions, the atoms are simply rearranged into new combinations.
True
Chemical substances that are produced in a reaction.
Products
