ACS GEN CHEM 1 FINAL reviewed exams
100% questions and answers
(J) mass (g) x specific heat (J x g⁻¹ x °C⁻¹) x ΔT (°C)
- ANSWER-Heat (q)
1. areas of high electron density "domains" repel each other
2. the electron domains arrange themselves as far apart as possible on the central atom
3. the molecule adopts whichever 3D geometry minimized this repulsion and this
controls the geometry around the central atom
- ANSWER-Valance Shell Electron Pair Repulsion (VSPEPR)
1. Energy can not be created or destroyed
2. energy of (system + surroundings) is constant
3. any energy transferred from a system must be transferred to the surroundings (and
vise versa)
4. ∆E = q + w
- ANSWER-First Law of Thermodynamics
1) All matter is made of atoms. Atoms are indivisible and indestructible.
2) All atoms of a given element are identical in mass and properties
3) Compounds are formed by a combination of two or more different kinds of atoms.
,4) A chemical reaction is a rearrangement of atoms.
- ANSWER-Dalton's Atomic Theory
22.414 L/mol @ STP
- ANSWER-Molar Volume of an Ideal Gas
7 Strong acids:
- ANSWER-HCl, HBr, HI (halides), HNO3, H2SO4, HClO3, HClO4
7 Strong Bases
- ANSWER-LiOH, NaOH, KOH, RbOH, Ca(OH)2, Sr(OH)2, Ba(OH)2
A covalent bond in which the two electrons derive from the same atom; occurs most
often between Lewis acids and bases.
- ANSWER-Coordinate Covalent Bonding
A molecule that is mostly positive on one side and mostly negative on the other.
- ANSWER-Polar Molecule
A species of an element in which the number of electrons does not equal the number of
protons.
- ANSWER-Ion
, a substance that does not form conducting ions, no charge
- ANSWER-non-electrolyte
a substances dissolves in water to give an electrically conducting soon by producing
ions, responsible for electric flow in soln
- ANSWER-electrolyte
added to cations formed from non-metals
- ANSWER-ium
added to represent the higher charged cations
- ANSWER-ic
added to represent the lower charged cations
- ANSWER-ous
added to the end of a monatomic anion (has 3 exceptions:)
- ANSWER-ide
more than one atom but still +ide:
hydroxide, cyanide, peroxide
all species listed as if they were molecules
- ANSWER-molecular equation
