Chm 1025 Formulas (Final) – ExamQuestions with Answers
Energy and heat capacity calculation - -Q(heat)=M(mass)*C(specific heat
capacity)* T ( temperature change)
-Density - -D=M/V
-Specific gravity - -SG= D of substance(g/ml) / D of water(g/ml)
-Conversion from Kevin(K) to Celsius (C) - -K=C+273.15
-Conversion from Fahrenheit(F) to Celsius(C) - -F=(C*1.8) +32
-Conversion from Celsius (C) to Fahrenheit(F) - -C= F-32/1.8
-Element - -Substance that can't be broken down into simpler substances
-Mixture - -Variable composition usually 2 substance that are combined
chemically
-Compound - -Two or more substances are chemically bonded
-Homogenous mixture - -
-What an electron falls from a higher level to a lower energy level, how is
the energy released? - -energy is released in the form of light
-The further the electron is from the nucleus, the _______energy the electron
has - -greater
-A(n) ____________is often thought of a region of space in which there is a
high probability of finding an electron - -orbital

Numbers
-how many electrons fill 2s - -2
-how many electrons fill 3p - -6
-how many electrons fill 5f - -14
-how many electrons fill 6d - -10
, -how many electrons fill 4p - -6

-Law of constant composition - -All sample of a given compound have the
same proportions of their constituent elements
-Mass ratio / provoking constant composition - -Mass ratio= mass of
elements/mass of elements . If the ratio of the first sample and second
sample are the same then the results are consistent with the law of constant
composition.
-What element usually goes first when naming elements - -The most
metallic one

element in the same physical state. (Ex. Carbon is graphite and as diamond)
-Empirical formula - -Gives the simplest whole-number ratio of atoms of
each element in a compound. (Ex. MF:H2O2 the empirical would be HO)
-Molecular formula - -Gives the actual number of atoms in a molecule of the
compound. (H2O2)
-Structural formula - -(H-O-O-H) uses lines to represent chemical bonds and
shows how the atoms in a molecule are connected to each other.
-Ball and stick model - -3D model of elements with balls and sticks
representing atoms and bonds
