Heat Transfer
What is Conduction?
transfer of heat through matter by direct contact of the particles
What is solubility
A measure of how well one substance dissolves in another
What are the Three Different Representations of Molecules?
Chemical Formula
Structural Formula
Condensed
What is molar mass?
The number of grams of an element or compound in one mole. (g/mol)
Define Arrhenius theory
defines acids and bases based on the IONS they PRODUCE
What is convection?
transfer of heat through the movement of heated particles
What are soluble solutes?
dissolve very well in water
produce high concentration of individual molecules (covalent compounds) in the solution
What Is an organic compound?
To be organic, (other than literally a handful of exceptions) you need a carbon bound to an H
That is really the more accepted definition of organic: Containing a C bound to H
How many moles of lithium in 14.0 grams of lithium?
2 mol
Define Bronsted-Lowry Theory
defines acids and bases based on the ROLE a species serves in a reaction (donate or accept an H+)
What is radiation?
transfer of heat through the emission of electromagnetic waves
What table do you use for solubility guidelines?
table F
What are the bonding properties of carbon?
Carbon has four valence electrons
Carbon must form four covalent bonds to be stable.
Carbon can form single, double, or triple covalent bonds
How many grams of LiF in 10 moles of LiF?
259 g LiF
What do Arrhenius acids produce?
H+ (Hydrogen ion)
What is thermal energy?
The total amount of energy in particles in a sample; generated by the movement of atoms or molecules in matter.
Define Miscible
liquids with high miscibility mix evenly
liquids will not form layers
Ex. Ethanol (alcohol) and water
What is saturated vs unsaturated?
Saturated: Maximum number of hydrogens possible given the number of carbons in the molecule.
Each C is bound to as many hydrogens as possible
ONLY SINGLE BONDS; Saturated–Single
NO double or triple bonds between carbon atoms!
Unsaturated: Less than the max # of hydrogens
Has at least one double or triple bond between carbon atoms
1 mole of gas equals how many liters of gas?
22.4 Liters
What will be the only positive ion in the
solution of H3PO4?
hydrogen ion , H+
hydronium ion, H3O
Measurement of units of heat
Joules
Indicate if the substance below is soluble or insoluble
iron(III) phosphate, FePO4
Insoluble
Which organic compound class is heptanone?
Ketone
What is the number of moles of hydrogen in a 100.-liter cylinder at STP?
4.46 mol H2
Explain what Bronstead Lowry acids vs bases do.
BrÖnsted-Lowry Acids donate protons (H+, hydrogen ion) in reactions
BrÖnsted-Lowry Bases: ACCEPT protons (H+, hydrogen ion) in reactions.
