Chemistry #2 Flashcards
Nuclei
Plural form of a nucleus
Nuclear Fission
A radioactive decay process in which the atom splits into to nuclei causing immense bursts of energy
Nuclear Fusion
A nuclear reaction from low atomic number elements in which they form to create a heavier nucleus that produces energy
Isotope
Two or more of the same atom form to produce the same element with the same amount of protons but different amount of neutrons. In summary it is a radioactive form of an element
Products
Chemical substances that result from a chemical equation
Reactants
The original substances present in a chemical reaction
Law of Conservation of Mass
Law that states that, in a chemical reaction, the total mass of the reactants is the same as the total mass of the products
Law of Constant Proportions
Law that states that, in chemical compounds, the ratio of the elements is always the same
Exothermic
Describes chemical reactions that give out heat energy to the surroundings
Endothermic
Describes chemical reactions that absorb heat energy from the surroundings
Chemical Energy
Energy stored in chemical bonds that is released during chemical reactions
Chemical Process
A reaction that changes the arrangement of the atoms or molecules of the substances involved
Dynamite
A relatively stable explosive invented by Alfred Nobel in 1866. It is created by mixing nitroglycerin with an absorbent substance such as silica, forming a paste that can be shaped into rods.
Nitroglycerin
A highly explosive liquid
Synthesis Reaction
A synthesis reaction is when multiple reactants form 1 single product. They release energy in the form of heat and light so it is exothermic
