polar molecules
what do polar molecules stick to?
polar molecules tend to stick together and line up in groups.
Are two atoms of the same element identical?
No. Two atoms of the same chemical element are typically not identical.
what does the number of moles tell you?
A mole fraction indicates the number of chemical elements.
what are gas laws?
gas laws consist of three primary laws, Charles Law, Boyle's Law and Avogadro's Law.
what is the gram formula mass?
the gram formula mass is a chemical compound that is defined as the mass of a sample of the compound that is divided by the amount of substance in the sample.
what causes polar molecules to form?
polar molecules start to form when two atoms do not share electrons equally in a covalent bond.
Does an atom have a color?
The answer really depends on how you define "having a color". The term "color" refers to visible light with a certain frequency, or a mixture of visible light frequencies. Therefore, the word "color" describes the frequency content of any type of visible light. Anytime visible light is present, we can describe it as having a certain color.
what are moles based on?
the moles are based on the number of atoms in a sample of the isotope carbon 12.
ideal gas laws does not work for low temperature, high density, and extremely high pressures.
what does the gram formula mass tell us?
the gram formula mass tells us the amount of compound that has the same mass in grams as the formula mass in atomic mass.
what do all polar molecules have?
all polar molecules have is an asymmetric shape, lone, electron pair, or a central atom bonded to other atoms.
Does an electron in an atom move at all?
an electron that is transitioning between states is moving from one state to the other.
how many molecules are in a mole?
why are gas laws important?
gas laws are important because they can be used to determine the parameters of a mass of gas using theoretical means.
do you round the gram formula mass?
you should always use the value rounded to two digits after the decimal point.
are polar molecules symmetrical?
all symmetrical molecules are non-polar.
How does dissolving a salt molecule in water make its atoms ionize?
Dissolving a salt molecule in water does not make its atoms ionize. The atoms in solid salts are already ionized long before touching water.
what is a mole?
the mole is the si base unit of amount of a substance.
do gas laws apply to solids?
gas laws do not apply solids and liquids.
is the gram formula mass the same as the molar mass?
Both are exactly the same.
how do polar bonds cancel out?
What makes radioactive atoms get old so quickly and decay?
Atoms don't age. Atoms radioactively decay when a lower-energy nuclear configuration exists to which they can transition.
is a mole equal to a gram?
the mass of 1 mole of a substance is equal to its relative atomic or molecular mass in grams.
what are the application of gas laws?
calculating the volume of oxygen available from a cylinder.
how many particles are in a gram?
1.4.
