Chemistry Calculators|教育線上App不用買

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)Others: Periodic Table Formal Charge Molecular Shapes Web viewer
