Chemistry Calculators

SHOWS WORK!
This application can be useful to anyone who is taking a first year chemistry class. It helps take you through some of the many ways to solve simple chemistry problems. Along with giving you the answer, it will also show the work that went into solving the problem. Remember to always do the problem yourself to make sure the answer is right!

Updates will be coming soon to add more calculators to the application, to help you with more advanced problems!

Formulas include:

Atomic Structure:
E=hv
c=λv
E = (-2.178*10^-18) / n^2

Equilibium:
Kw = Kb*Ka
Kw = [H+]*[OH-]
Kc = Products / Reactants
Delta G = -RT*ln(K)
pH = -log[H+]
pOH = -log[OH-]
14 = pH +pOH
14 = pH + pOH
H+ = 10^pH
OH- = 10^pOH
pH = pKa + log[salt / acid]

Gas, Liquids, And Solutions:
PV=nRT
(P1 * V1) / T1 = (P2 * V2) / T2
V1 / N1 = V2 / N2

Thermochemistry/Kinetics:
Delta H = Products / Reactants
Delta S = Products / Reactants
Delta G = Products / Reactants
Half-Life = .693 / Rate Constant
Others:
Periodic Table calculations(grams per mole and grams needed)
FC = Valence Electrons - (Loan Electrons + Bonding Electrongs / 2)
M=moles/Volume(L)
