Iron will have a +2 charge (hence the name iron(II)), and chloride ions will have a -1 charge, meaning to balance it, you need two chloride ions to each iron, making the formula FeCl2.
There is one iron ion in each molecule, meaning it is one to one with the molarity:
1 iron ion * (0.0550 moles/liter) = 0.0550 moles iron/liter = 0.0550M Fe
There are two chloride ions in each molecule, meaning it is two to one with the molarity.
2 chloride ions * (0.0550 moles/liter) = 0.110 moles chloride/liter = 0.110M Cl
Answer:
1.4 mols
4th answer
Explanation:
22. 5 g of O2 in moles = (22.5/32) mols = 0.703 mol
The stoichiometry between O2 and H2O =1: 2
Therefore H2O produced = 2 * 0.703 mols=1.406 mols
Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element oxygen. This type of molecule is called a diatomic molecule, a molecule made from two atoms of the same type
