substances that are formed as a result of a chemical reaction f. product
ocurs when bonds are broken and reformed to make a new substance or substances b. chemical changes
substances that change in a chemical reaction e. reactants
the total mass of the products of the reaction is equal to the total mass of the reactants c. Law of conservation of mass
an example is the formation of polymers d. synthesis reaction
a reaction in which one element replaces a similar element in a compound a. single- displacement reaction
a reaction in which a substance combines with oxygen releasing large amounts of energy in the form of heat and light e. combustion reaction
a reaction in which ions from two compounds in a solution exchange places to produce two new compounds b. double-displacement reaction
a reaction in which a single compound is broken down c. decomposition reaction
converts glucose and oxygen into energy, carbon dioxide and water respiration
an example of an exothermic reaction is: heating MREs by pouring water into the ration heater
when you activate an instant cold pack, water mixes with a chemical and the pack gets very cold. This is an example of: endothermic reaction
classify the following reaction :3CuSO+2Al -> Al(SO) +3Cu single-displacement
