Gravitational force is the result of masses ( Fg= GmM/r^2) and electric forces is the result of charges Fe = kqQ/ r^2).
three types of electrical charges are, electric charges natural charges unnatural charges
Like charges repel, unlike charges attract.
No not always. There could be from negative charges to positive charges. !
Fe and either 3+ or 2+
== == Fe+2 PO4-3 <---- these are the ions and their charges Fe+2 Fe+2 Fe+2 PO4-3 PO4-3 <---- the charges have to add up to zero, so three +2 iron ions cancel out two -3 phosphate ions Fe3(PO4)2 <---- simplify
These are the ions and their charges: Fe+3 S-2The charges have to add up to zero, so two +3 iron ions cancel out three -2 sulfur ions: Fe+3 Fe+3 S-2 S-2 S-2Simplify: Fe2S3
Fe+2 S-2 <---- these are the ions and their charges FeS <---- the charges have to add up to zero, so one +2 Fe ion cancels out one -2 S ion FeS <---- final answer
Iron ions, Fe+3, will bind to oxygen ions, O-2, in a ratio that depends on their charges since the total positive charges in the molecule must equal the total negative charges. The eventual number of positive and negative charges is found by the least common multiple of the charges. In this instance, the charges are 3 and 2. The least common multiple is 6, so two atoms of the Fe+3 are needed to have a total positivie charge of +6, and three O-2 are needed to have a total negative charge of -6 to provide the electrical balance. The resulting molecule is Fe2O3.
Fe+3 Cl-1 --------> These are the ions and their chargesFeCl3 ----------> This is the formula when the charges add up to zeroFeCl3
Iron(II) compounds contain ions with 2 positive charges, iron(III) ions have 3 positive charges.
Fe+3 SO3-2 ------> these are the ions and their charges. Sulfite's charge is -2 and Iron's charge is +3 (you know this because of the (III)Fe+3 Fe+3 SO3-2 SO3-2 SO3-2 ------> the charges have to add up to zero, so two +3 Fe ions equal +6 and three -2 Sulfite ions equal -6.Fe2(SO3)3 -----> simplify
These are the ions and their charges: Fe+3 SO3-2The charges have to add up to zero, so two +3 iron ions cancel out three -2 sulfite:Fe+3 Fe+3 SO3-2 SO3-2 SO3-2Simplify: Fe2(SO3)3
