3. Ion - ANSWER ✔ Atom that has lost or gained an electron
4. Compound - ANSWER ✔ 2+ different elements
5. Diatomic elements - ANSWER ✔ H2, N2, O2, F2, Cl2, Br2, I2
6. Allotropes - ANSWER ✔ Elemental molecules with different formulas
7. Ionic compounds - ANSWER ✔ Metal and nonmetal (can be polyatomic
too)
8. Molecular compounds - ANSWER ✔ Two or more nonmetals
,9. Naming ionic compounds - ANSWER ✔ 1. name the metal
2. write the metal's oxidation state as a Roman numeral in parenthesis (skip
for columns one and two)
3. Name the nonmetal using an "ide" ending
10.A 0.02 mol sample of an ideal gas in a sealed 1.0 L container was heated
from 27C to 227C. What is the pressure of the gas at this new temperature? -
ANSWER ✔ 0.821 atm
11.A mixture of 0.04 mole of gas A and 0.1 mole of gas B was allowed to react
at 300 K in a 1 L sealed container. At the end of the reaction, what is the
total pressure of the mixture? (the temp and volume remain constant during
the reaction) - ANSWER ✔ 2.5 atm
12.Dalton's law of partial pressures - ANSWER ✔ Ptotal=Pa+Pb+Pc...
13.Ion-dipole - ANSWER ✔ Intermolecular force between ion and polar
substances (NaCl in water) strongest
14.Hydrogen binding - ANSWER ✔ N-H
F-H
O-H
bond in pure substance
15.Dipole-dipole - ANSWER ✔ Intermolecular force between polar molecules
, 16.London dispersion forces (Van der Waals) - ANSWER ✔ Intermolecular
force between all molecules
- Temporary dipole, includes polar and nonpolar molecules
- The greater the weight, the greater the London dispersion forces.
17.Higher intermolecular forces lead to - ANSWER ✔ higher boiling point
higher heat of vaporization
higher viscosity
higher surface tensions
LOWER vapor pressure
18.Pure gases - ANSWER ✔ Weak intermolecular forces
Low BP
Low MP
Purely covalently bonded and nonpolar
19.Higher boiling point - ANSWER ✔ Lower vapor pressure
20.heat of fusion - ANSWER ✔ the
Energy required to change a solid at its melting point to a liquid
21.Heat of vaporization - ANSWER ✔ Defined as the energy required to
change a liquid at its boiling point to a gas
22.Vapor pressure increases as water temp inscreased until boiling point -
ANSWER ✔ 760 tore or 100°c
23.H20 issss - ANSWER ✔ Polat
