atomic notation - Answer top number=atomic mass=protons neutrons, bottom number=atomic number=number of protons in nucleus=number of electrons subatomic particle masses - Answer protons and neutrons - 1amu, electrons have almost no mass find number of neutrons - Answer the number of protons is the same as the atomic number, and you know the mass number, solve out for neutrons cations vs anions - Answer cation gives away electrons, anion receives electrons, cation...

what deviates the most from the ideal gas law - Answer the biggest molecule alternate formula for density - Answer pm/rt less steric class - Answer low energy hydrogen bond acceptor - Answer partially negative N,O,F with a lone pair hydrogen bond donor - Answer partially positive H bound to N,O,F functional groups that are weak electrolytes - Answer amine carboxylic acid ether - Answer single bond esther - Answer double bond o...

standard states of elements - Answer All metals and metalloids are solids at standard state except for mercury, which is a liquid. Noble gases (group 8) are all monatomic gases. Several elements exist as diatomic species at standard state, these include group 7 (F2, Cl2, Br2, and I2) plus hydrogen (H2), nitrogen (N2), and oxygen (O2). All of these diatomic species are gases at standard state except for Br2 (liquid) and I2 (solid). All other nonmetals are solids. Carbon----> graphite ...

how to find mass number - Answer protons + neutrons atomic number - Answer number of protons anions - Answer negatively charged ions cations - Answer positively charged ions ions - Answer charged atoms atomic weight - Answer average mass of all isotopes how to find atomic weight - Answer sum of atomic mass x relative abundance molecule - Answer group of atoms bonded together Avogadro's number - Answer 6.02 x 10^23 ...

Chapter One: Matter and Energy (Sections 1-7) - Answer topics covered: atomic structure Avogadro's # ions and molecules intro to energy enthalpy light energy spectroscopy atoms - Answer the smallest units of matter that correspond to the elements on the periodic table equation to calculate the energy needed to break a bond of wavelength - Answer (avogadro's #)(h)(c)/ Bond disassociation energy Avogadro's number - Answer 6.02 x 10^23 What do atom...

Chemical Properties - Answer qualities that a substance shows as it transforms or interacts with other substances flammability, corrosiveness, reactivity with acids Physical Properties - Answer qualities a substance shows without interaction with other substances color, hardness, density, boiling point, viscosity, electrical conductivity, melting point Intensive property - Answer a property independent of amount Substance - Answer a type of matter that has a de...

Gibbs free energy - Answer ∆G - the maximum amount of work that can be obtained from a process ∆G at equilibrium - Answer ∆G = 0 The function of a salt bridge - Answer It allows electrical neutrality to be maintained by the flow of appropriate ions between the half-cells In the copper-silver cell, why must the Cu2+ and Ag+ solutions be kept in separate in containers? - Answer Otherwise Ag+ ions would be reduced directly by Cu metal and no external current w...

What kind of bond is in a Single Bond - Answer one sigma bond What kind of bond is in a Double Bond - Answer one sigma bond and one pi bond What kind of bond is in a Triple Bond - Answer one sigma and two pi bonds Sigma Bond - Answer - results from head-on overlap of orbitals - electron density is symmetric about the internuclear axis between nuclei Pi Bond - Answer - results from sideways overlap of orbitals - electron density is above and below the...

ionic bonding - Answer atom donating an outer electron to another atom to make oppositely charged ions attract each other atoms in ionic bonds - Answer one positive atom and one negative atom ions - Answer atoms that went through ionic bonding ionic bonds occur between - Answer metals and nonmetals covalent bonding - Answer atom sharing an outer electron to another atom covalent bonds occur between - Answer nonmetals only where to find covale...

Atom - Answer the smallest representative particle of an element that can enter into chemical combinations retains its identity during chemical reactions Proton - Answer a subatomic particle found in the nucleus has a positive charge equal in magnitude but opposite in sign of an electron Neutron - Answer a neutral subatomic particle found in the nucleus of an atom almost identical mass to a proton Electron - Answer a negatively charged subatomic particle f...
