What does two moles next to the eye mean?
Two moles is 12,044 280.10e23 molecules, atoms or ions.
How much is 2 scientific moles?
Two moles is equivalent to 12,044281714.10e23 molecules, atoms or ions.
How many moles of OH ions are produced from the hydroxides of group ii metals for every mole of the base that dissociates?
That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
How many moles of water H2O are produced from the reaction of 16 grams methane CH4 with an unlimited supply of oxygen O2. How many grams of H2O is this?
Two moles of water are produced.
How many moles of electrons are required to reduce one mole of nitrogen gas N2 to two moles of nitrogen ions N3-?
Each of the nitrogen atoms in N2 needs three electrons, for a total of six.
How many sodium ions in 2.00 mol of NaCI?
There are two moles of sodium ions in two moles of sodium chloride.
When 0.5 moles of Na2SO4 is dissolved in water how many moles of sodium ions are present?
Since the formula shows two sodium atoms in each formula unit of sodium sulfate and this compound normally completely ionizes in water solution, the number of sodium ions will be twice the number of moles of the salt; in this instance, 1.0 moles of sodium ions.
How many ions does MgBr2 have?
One formula unit of MgBr2 has three ions; one Mg2+ ion and two Br- ions. One mole of MgBr2 formula units has one mole of Mg2+ ions and two moles of Br- ions, for a total of three moles of ions.
How many moles of ions are produced by the dissociation of 1 mole NH4Br?
I assume that is 28.0 grams.28.0 grams MgCl2 (1 mole MgCl2/95.21 grams)= 0.294 moles magnesium chloride==========================Now,One mole Mg 2+ = 0.294 moles Mg 2+ ions=============================2 moles Cl - = 0.588 moles Cl - ions=========================

That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
What is the dissociation of cobalt II nitrate?
Cobalt(II) nitrate dissociates as follows:Co(NO3)2 ==> Co^2+ + 2NO3^-
How many components are in salt and water when combined?
1,000,000,000,000,000,000,000,000,000,000,000 for you
How many chloride ions are in calcium chloride?
The formula unit for calcium chloride is CaCl2. There are two chloride ions in one formula unit of calcium chloride. We can also say that there are two moles chloride ions in one mole of CaCl2.
How many moles of solute particles are produced by adding one mole of sodium nitrate to water?
two moles
How many chloride ions are in sample of salt that contains 2 moles of MgCl2?
Two Chloride ions (2Cl-) ions are needed with their -1 charge on each one to cancel out the +2 charge of the single Magnesium ion (Mg2+). So Magnesium Chloride would have the chemical formula: MgCl2
