Science Flashcards
Group of laws that govern the behavior of gases.
gas law
The 4 laws are:
Boyle’s Law, Charles Law, Gay-Lussacs Law and The Combined Gas Law.
- discovered Boyles’s law which states that the pressure and volume of a gas are inversely proportional.
Robert Boyle
This means that as the pressure of gas increases, its volume decreases.
boyle’s law
The equation states that the product of pressure and volume is a constant for a given mass of combined gas as long as the ___
temperature is constant.(boyle)
P1V1 = P2V2
Boyle
, a french chemist.
• It states that at a constant pressure, the volume of a gas is directly proportional to the temperature (in Kelvin) in a closed system.
Jacques Charles
This law states that
• The pressure of the gas is directly proportional to the temperature for a constant volume.
Joseph Louis Gay-Lussac
It shows the relationship between temperature, volume and pressure for a fixed quantity of gas.
combined gas law
Is the shorthand way of expressing chemical reaction using numbers, symbol and formula.
chemical equation
Two major parts
• t
Reactant
• Product
the term for substances that start a chemical reaction
reactant
the substances formed as a result of a chemical reaction is called.
Product
•The starting materials
•These are the substances that changes when it is combined with another substance in a chemical reaction
reactant
•The new substance
•The substances that result of the chemical reaction
products
used to separate one reactant or
product from one another.
plus sign +
Can be read as “reacts with”
when used in reactant, read as
“and” when it is used in product.
+
used to separate the reactants
from the products
arrow to the right
read as “yields” or “produces” in
an equation.
arrow to the right
•indicates that the substance is in
the solid state.
(s)
indicates that the substance is in the liquid state.
(I)
indicates that the substance is in
the gas state.
(g)
indicates that the substance is
dissolved in water
• comes from the term “aqueous”
(aq)
indicates that there is heat
applied or needed to make the
reaction proceed.

According to the law of ____, matter cannot be created nor destroyed. It is only converted from one form to another.
conservation of mass
In essence, the number of atoms of all elements in a chemical equation should be ____
be the same.
If they are not, you need to work on providing integer numbers preceding each reactant or product. These numbers are called __.
coefficients
These ___ represent the number placed in front of chemical formula to balance equation.
coefficients
is the number appear on the bottom left or right of the symbol.
