PO4 NEG 3 plus BA POS 2?
This is not a math question, this is a chemestry question.
How do you find the number of bond pairs?
Type your answer here...Bond pairs1. Determine the column each element is in.2. That is the number of valence electrons each atom has available for bonding.3. Add up the valence electrons for all the atoms on the compound to determine the number of electrons available for bonding. For polyatomic ions such as sulfate with a negative 2 charge, the negative 2 means there 2 more electrons available for bonding.4. Each atom needs 8 electrons to have an octet, 8 electrons in the outer shell, so multiply the number of atoms by 8 (except H by 2) to determine the number electrons needed. (except Hydrogen which only needs 2 electrons to fill its 1s orbital)5. Subtract the number of electrons available from the number electrons needed. (Step#4 - Step#3) This answer is the number of electrons involved in bonding.6. Divide this number by 2 to determine the number of bonds pairs needed.7. You place the least electronegative atom in the center8. Place these bonds pairs between the atoms. One line represents a bond (2e-'s)9. Place enough electron pairs around each atom to make an octet(except hydrogen only needs 2e-'s). One line represents a pair of e-'s.10. Check to make sure the number of electrons used equals the number of valance electrons available .(#3)11. Check the shape. Electron pairs repel each other, so make sure the bonds are as far away from each as possible.Example #2 Sulfur dioxide SO21. Column #'s S = 6, O = 6.2. 6 + (2 * 6) = 18 electrons available for bonding.3. 3 atoms * 8 = 24 electrons needed in total.4. 24 - 18 = 6 electrons involved in bonding.5. 6 ÷ 2 = 3 bond pairs.6. S in center, O's on the outside.7. 3 bonds between bonding 2 O's to an S. That means a single and a double bond.8. The S has 1 nonbonding pair, 1 O has 1 nonbonding pair, the other O has 2 nonbonding pairs.9. Count 18 electrons.10. The shape will be Y-shaped.Example #1 Phosphate ion, PO4, -3 charge1. Column #'s P = 5, O = 6.2. 5 + (4 * 6) + 3(-3 charge) = 32 electrons available for bonding.3. 5 atoms * 8 = 40 electrons needed in total.4. 40 - 32 = 8 electrons involved in bonding.5. 8 ÷ 2 = 4 bond pairs.6. P in center, O's on the outside.7. 4 bonds between bonding 2 O's to an P. That means 4 single bonds.8. Each O atom will need 3 nonbonding pairs.9. Count 32 electrons.10. The shape will be Tetrahedral-shaped.
What is the formula of disodium ammonium phosphate?
The formula for disodium ammonium phosphate is Na2H(NH4)(PO4).
Is calcium sulphate phosphate?
No, calcium sulfate and calcium phosphate are two distinct compounds. Calcium sulfate is commonly known as gypsum, while calcium phosphate is a group of minerals found in bones and teeth, such as hydroxyapatite.
What is the formula of a compound that contains Na plus and PO43- ions?
The formula of the compound containing Na+ and PO43- ions is Na3PO4. This is because the charges of the sodium ion (Na+) and the phosphate ion (PO43-) balance out when three sodium ions combine with one phosphate ion.
What is the chemical formula for a compound made up of Ca2 plus and (PO4)3 and minus?
For example a calcium phosphate as Ca3(PO4)2.
What is the name of anion PO4-3?
PO43- is the ion called (Ortho)Phosphate. It comes from (Ortho)Phosphoric Acid [H3PO4].
Chemical formula of disodium pyrophosphate?
Disodium pyrophoshate refers to Sodium Dihydrogen Pyrophosphate. Its formuyla is Na2H2P2O7
What is the chemical name when adding PO43- plus Co2 plus?
Cobalt phosphate has the chemical formula Co3(PO4)2.
What is the product of Na3PO4 plus NiCl2 do I put PO4 in parenthesis and add a 3 subscript?
Yes, you need to put the PO4 in parentheses and add a 3 subscript to indicate that there are 3 phosphate ions in the compound. The product of Na3PO4 + NiCl2 would be Ni3(PO4)2 + 6NaCl.
3caso4 plus 2Na3po4?
The chemical equation is: 3CaSO4 + 2Na3PO4 → Ca3(PO4)2 + 3Na2SO4
PO4 NEG 3 plus BA POS 2?
This is not a math question, this is a chemestry question.
How do you complete this equation K3PO4 plus BaCl2?
2K3PO4 + 3BaCl2 -> Ba3(PO4)2 + 6KCl
What is the chemical equation for the preparation of super phosphate?
Rock phosphate is made to react with concentrated sulphuric acid which produces a mixture of calcium sulphate and calcium-di-hydrogen phosphate. This is super phosphate.Equation Ca3(PO4)2+2H2SO4 => 2CaSO4+Ca(H2PO4)2
