What are the units of the Coulomb constant k which appears in Coulomb's law?
newtons * meters squared / coulombs squared
What is the value for Coulombs constant k?
8.998 X 10^9 N*m^2/C^2
What is the constant equal to the ratio of the gas constant to the avogadro constant?
Boltzmanns constant
Is the spring constant is constant on the moon?
no the spring constant is not constant on moon because there is no restoring force there
Does the gas constant R vary with temperature?
No, the gas constant, or any constant, is constant meaning it doesn't change.
What is the unit of coulombs law the constant of proportionality has?
The unit of the constant of proportionality in Coulomb's law is Nm²/C² or Vm.
What is Avogardo's constant used for?
Well it is used in certain Chemical equations and to derive other constants. As an example the charge on an electron = 1.6019 x 10-19 coulombs. So a mole of electrons will be 6.023 x 1023 (Avagadro) x 1.6019 x 10-19 coulombs per mole = 96495 coulombs per mole which is Faraday's constant

What mathematical expression identifies the number of coulombs necessary to produce one mole of iron metal from an aqueous solution of iron III sulfate?
The mathematical expression is Q = nF, where Q is the total charge in coulombs, n is the number of moles of electrons transferred (in this case, 3 moles for iron III sulfate to iron metal), and F is the Faraday constant (96,485 C/mol). Therefore, the number of coulombs necessary would be Q = 3 * 96485 C/mol = 289,455 C.
Faraday law of elecrolysis?
W = (I*t*A)/(n*F)where:W = weight of plated metal in grams.I = current in coulombs per second.t = time in seconds.A = atomic weight of the metal in grams per mole.n = valence of the dissolved metal in solution in equivalents per mole.F = Faraday's constant in coulombs per equivalent. F = 96,485.309 coulombs/equivalent.
What are the limitations coulombs law?
Limitations of coulombs law
What is the different between Coulomb and Faraday?
Coulomb is a unit of electric charge while Faraday is a unit of electric charge quantity present in one mole of electrons. One Coulomb is equal to one Faraday constant, which is approximately 96,485 coulombs.
What is the population of Germigny-sous-Coulombs?
Germigny-sous-Coulombs's population is 194.
What is the population of Coulombs-en-Valois?
The population of Coulombs-en-Valois is 606.
What is the variable for coulombs?
The variable for charge in coulombs is typically represented by the letter "Q".
If a piece of jewelry were electroplated with gold for 25 seconds at 1.5 A how many grams of gold would be plated?
To calculate the grams of gold plated, you first need to determine the total charge passed through the circuit. This requires multiplying the current (1.5 A) by the time (25 seconds), which gives 37.5 coulombs. Knowing the charge and the Faraday constant (96,485 coulombs), you can then convert coulombs to moles and moles to grams to find out the amount of gold plated.
