FUNDAMENTAL LAWS Flashcards
this law states that matter can neither be created nor destroyed. In other words, the total mass, that is, the sum of the mass of reacting mixture and the products formed remains constant
Law of Conservation of Mass
_______ _______gave this law in the year 1789 based on the data he obtained after carefully studying numerous combustion reactions.
Antoine Lavoisier
a French chemist stated that the proportion of elements by weight in a given compound will always remain exactly the same
joseph proust
the per cent composition of elements by weight in a given compound will always remain the same.
Law of Definite Proportions (Proust’s law)
This law states that if two elements combine to form more than one compound, the masses of these elements in the reaction are in the ratio of small whole numbers
Law of Multiple Proportions
who gave the law of multiple proportions
john dalton
This law states that when gases are produced or combine in a chemical reaction, they do so in a simple ratio by volume given that all the gases are at the same temperature and pressure
Gay Lussac’s Law of Gaseous Volumes
This law can be considered as another form of the law of definite proportions
Gay Lussac’s Law of Gaseous Volumes
Defined as the number of particles per mole (Molecules, atoms, compounds, etc.) of substance.
Avogadro’s Law (aka Avogadro’s constant.)
bond Between Metals and Nonmetals.
ionic bond
LEORA
lose electron, undergoes oxidation, serves as reducing agent
GEROA
gain electrons, undergoes reduction, serves as oxidizing agent
bond Between Nonmetals and nonmetals.
covalent bond
electron shared unequally
polar covalent
electron shared equally
non polar covalent
