How many moles in 79.3g CL2?
The gram molecular mass of Cl2 is 70.906, twice the atomic mass of chlorine atoms. Therefore, 79.3 grams of Cl2 contains 79.3/70.906 or 1.12 moles, to the justified number of significant digits.
What is the atomic number of a chloride ion?
The atomic number of chlorine (Cl) is 17. The atomic weight of Cl is 35.4527 grams per mole.Chlorine gas exists as a diatomic molecule: Cl2.See the Web Links to the left of this answer for a periodic table with more information about this element!17one
What is the maximum mass of aluminum chloride that can be formed when reacting 13.0 of aluminum with 18.0 of chlorine?
I'm assuming you mean 13g of Aluminum and 18g of Chlorine Atomic mass of Al = 27g/mol number of moles = mass / atomic mass = 13g / 27g/mol = 0.481mol Molecular mass of Cl2 = 2(35.5) = 71g/mol number of moles = mass / atomic mass = 18g / 71g/mol = 0.254mol The balanced equation for reaction between Aluminum and Chlorine: 2Al + 3Cl2 --> 2AlCl3 The ratio of Al to Cl2 is 2:3 and there's only 0.254mol of Cl2 therefore it's completely reacted and Al is in excess. The ratio of Cl2 to AlCl3 is 3:2 and 0.254mol of Cl2 so there's (0.254mol x 2/3) = 0.169mol of AlCl3 formed. Molecular mass of AlCl3 : 27 + 3(35.5) = 133.5g/mol mass = number of moles x molecular mass = 0.169mol x 133.5g/mol = 22.56g of AlCl3
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?
Which element has an atomic number between 27 and 31?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
What is chlorine gases number of atomic mass?
Chlorine gas is Cl2. Cl's atomic mass is 35.45 and that x 2 is 70.9
What has the larger atomic radius Cu or Cl2?
The atomic mass of Cu is: 63.546 g.mol The atomic mass of Cl2 is: 35.453 g.mol So your answer would be: Cu has the largest Atomic mass.
How many moles in 79.3g CL2?

Which neutral molecule would be isoelectronic with ClO?
Cl2, O has atomic number 8, Cl has atomic number 17 so in OCl- , there are 26 electrons. ClF has the same number of electrons, Cl atomic number 17, F atomic number 9- this is an interhalogen, chlorine monofluoride. A quick way is to look for an atom with an atomic number one higher (that's to compensate for the electron) than either Cl or O. You can ignore Cl as the atom with atomic number 18 is argon a noble gas- one higher than Cl is F.
How many moles K are needed to react with 15 moles of Cl2?
H2 +Cl2---------------->2HCl Since H2 and Cl2 react in 1:1 mole ratio the number of moles of H2 reacting is equal to the number of moles of Cl2 which is equal to 0.213
