Q

What is Ideal Gas?

A

It is a hypothetical gas of molecules that follow the laws; they do not attract/repel one another, and take up no space (have no volume)

Q

What is the Molar Mass?

A

The molar mass is the measurement(amount) of a substance, measured in moles (6.02 x 10^23). It is per 1 mole of substance (5g/mol has 5g of mass per 1 mole of substance)

Q

What is a solvent?

A

A solvent is the substance in a solution that does the dissolving (eg water)

17
Q

What is an Atmosphere?

A

It is a mixture of gases that surround the earth, and is usually used as a form of measurement (1 atm == 14.7 lb/in2, 1 atm == 101 325 Pa)

18
Q

What is the Combined Gas Law?

A

A law that states that the ratio between pressure, volume, and absolute temperature of a gas equals some constant (P¹V¹/T¹ == P²V²T²)

19
Q

What is the Ideal Gas Law?

A

A law that states that the product of the pressure & the volume of one gram molecule of ideal gas == the product of the absolute temperature of the gas and the universal gas constant.

20
Q

What is SATP?

A

The Standard Ambient Temperature & Pressure is used as a reference, where 25C (298.15K), and 1atm (101.325kPA) are stated

21
Q

What is an isotope?

A

An isotope is a rarely occuring form of an element where it has less/more neutrons than usual, but still stable. This is why the periodic table has big decimal values of atomic mass.

22
Q

What are Valence Electrons?

A

Valence Electrons are the electrons on the outermost shell (orbital) of an atom. They can freely move from atom to atom and try their hardest to make a neutrally charged atom.

23
Q

What is Isotopic Abundance?

A

Isotopic Abundance states that Isotopes of a given element do not all exist in equal ratios

24
Q

What is Avogadro’s Number?

A

Avogadro’s Number is the number used to state how many particles per mole there are. The number is 6.02x10^23

25
Q

What is Dilution?

A

Dilution is when you add more Solvent to a solution, so that the overall concentration of the solute is less.

26
Q

What is a Solute?

A

A solute is the substance being dissolved in a solution, such as sugar in lemonade

27
Q

What is Boyle’s Law?

A

Boyle’s Law states that the pressure and volume of a gas have an inverse relationship. If volume increases, pressure decreases and vice versa.

28
Q

What is Gay-Lussac’s Law?

A

It states that the pressure of a given amount of gas held at a constant volume is directly proportional to the Kelvin temperature.

29
Q

What is Kilopascals?

A

Kilopascals is the measurement of pressure (Pa) in 1000’s. 1kPA == 1Pa

30
Q

What is Kelvin?

A

A Kelvin is a measurement of temperature. 0 Kelvin is the temperature that particles stop moving entirely (at -273.15C).
