chemistry Crossword

Homogenous mixture; solid, liquid, or gas
The substance that is being dissolved
The medium that is dissolving another substance
Particles > 100 nm; settle to the bottom (sand & water)
Particles 1-100 nm; suspended throughout the medium Scattering of light
Conduct electricity when dissolved in a solution Ionic Compounds
Do not conduct electricity Covalent Compounds
S1 /P1 = S2 / P2 The solubility of a gas in a liquid is directly proportional to the partial pressure of the gas on the surface of the liquid
The FIZZING that happens when you open the pop; the release of gas from a solution
M = mol solute / L solution
m = mol solute / kg solvent
mass solute x 100 / mL solution
vol solute x 100 / vol solution
The inward force or pull that tends to minimize the surface area of the liquid; Water tends to drop in spheres; Water not attracted to air molecules
Creates a large network between adjacent molecules; Forms a ‘skin’
The greater the intermolecular forces the more spherical the drop
Pressure created as molecules that escape from the liquid phase to the gaseous phase; Hydrogen Bonding ; Holds molecules tightly, does not allow escape
The amount of heat required to change the temperature by 1°C; High Specific Heat = 4.18 J/g °C; Helps to moderate air temperatures
Extensive bonding requires large amounts of heat to disrupt; Boiling point: 100°C
As water cools, it starts to contract, causing mass to decrease while volume remains constant.; D = M/V; 10/10 = 1 5/10 = ½; At 0°C ice has 10% greater volume than water, therefore a lower density.
