Enhanced Chemistry Flashcards
Gas laws
A basic law in chemistry describing the behavior of gas held at a constant temperature.
Discovered in 1662
Boyle’s law
where volume is inversly proportional to pressure of gas .
P(1), V(1) = P(2), V(2)
Gas laws
The force exerted by gas against the walls of the container.
Pressure (P)
Gas laws
Determines the kinetic energy and rate of motion of the gas particles.
Temperature (T)
Gas laws
Where volume is directly proportional to the temperatue at constant pressure
By Jacques ________ (1746 - 1823)
Charles’ Law
V(1)/ T(1) = V(2)/ T(2)
Gas laws
(blank) Explains the laws that describe the behavior of gases.
Kinetic theory
Kinetic molecular theory of gases
Gas laws
The space occupied by the gas
Volume (v)
Gas laws
The quantity of has present in a container
Amount (n)
Gas laws
What is the formula for the combined gas law? where pressure, temperature, and volume is present.
(P1)(V1)/ T1 = (P2)(V2)/ T2
The combination of Boyle’s law, Charles’ LAw and Gay-iussac’s law
Gas laws
who’s number is this?
6.02 x 10^23
Avogadro’s law
Gas laws
It states taht the ratio of the product of pressure and volume and the absolte temperature of gas is equal to a constant
The combined gas law
Gas laws
Define the IDEAL GAS LAW
It is when Avogadro’s law is added into the combined gas law.
Gas laws
what is the equation for the ideal gas law?
PV=nRT
Gas laws
“Equal volumes of all gases, kept at the same pressure and temperature, contain the same number of molecules.”
The ideal gas law
A (Blank) is a group of 2 or more atoms, held together by chemical bonds, and can contain different elements.
A molecule
(blank) consists of 2 or more substances that are not chemically combined together.
A mixture
(blank) are substances that contains 2 or more different elements, held together by chemical bonds; are always found i the same proportions.
A compound
what are the two types of mixtures?
Homogenous and heterogenous
A composition or mixture that has non-uniform composition.
Heterogeneous mixture
A composition that remains uniform throughout the entire sample.
Homogeneous mixture
A mixture of 2 or more substances in the same phase
solution
A substance that dissolves to form a solution
Solute
A substance that dissolves a solute
Solvent
Chemical reactions
Two ionic compounds exchange ions, resulting in the formation of two new compounds.
Double displacement
Chemical reactions
The separation of a combined substance into multiple products
Decomposition reaction
Chemical reactions
One element replaces another element in a compound
Single displacement
Chemical reactions
Occurs when two or more substances combine and form a compound
Synthesis/combination reaction
The speed of the reaction
Rate of reaction
Reactions take place when particles collide with a certain amount of energy.
Rate of Reaction
The minimum amount of energy needed for the particles to react.
activation energy
Rate of Reaction
is it effective or not? when colliding molecules posses a minimum kinetic energy to start a chemical reaction.
Effective
Rate of Reaction
A way in which scientists explain how particles react.
particles eithe moves fast or slow depending on how much energy they have
The collision theory
Rate of Reaction
is it effective or not? when the reactant molecules did not go in the correct orientation when they collide.
not
The reactant molecules should be in correct orientation when they collide.
Rate of Reaction
what are the factors affecting the rate of reaction?
Temperature, surface area, concentration, prescence of a catalyst
