What are the individual ions for lithium cyanide?
li+ and CN-
Is electrolysis of water chemical change or physical change?
It is a chemical change because you are breaking the water into its elements, hydrogen and oxygen, and it is no longer water. I NEED THE NUMBER'S ^ Here They are Oxidation of ions or neutral molecules occurs at the anode, and the reduction of ions or neutral molecules occurs at the cathode. For example, it is possible to oxidize ferrous ions to ferric ions at the anode:Fe2+ aq → Fe3+ aq + e- It is also possible to reduce ferricyanide ions to ferrocyanide ions at the cathode:Fe(CN)3- 6 + e- → Fe(CN)4- 6
Is NaCN soluble or insoluble and which ions would be present in an aqueous solution if any?
NaCN is soluble in water. The ions present would be the sodium ion (Na+) and the cyanide ion (CN-).
Is electrolysis of water to form hydrogen and oxygen a physical or chemical change?

What are bonds in KCN?
Ionic Bond between K+ and CN- ions. The C and N in CN_ ion are bonded by covalent sigma and pi bonds.
Balance an equation by oxidation method?
k2cr2o7+FeSO4+H2SO4 --> Cr2(SO4)3+Fe2(SO4)3+K2SO4+H2O
What are the individual ions for lithium cyanide?
li+ and CN-
Formula for barium cyanide?
Be(CN)2 Since Be occurs as Be2+, it takes 2 (CN)- ions.
How many ions are in tin 4 cyanide?
Tin(IV)cyanide is Sn(CN)4 and will dissociate into five ions.

Give an example of a polyatomic ion?
HCO3 - CO3 2- CLO - FLO - BrO3 - IO3 - NO3 - PO4 3- SO4 2- These are "ate" ions if you subtract one oxygen by adding one more hydrogen, this would make it "ite' ion. There is -1 charge; subtract one from the charge. ex. CO 3 2- turns into HCO3 -
Is NaCN soluble or insoluble and which ions would be present in an aqueous solution if any?
NaCN is soluble in water. The ions present would be the sodium ion (Na+) and the cyanide ion (CN-).
What carries the negative charge on ferrocyanide?
Ferrocyanide carries the negative charge in the form of the ferrocyanide ion, which is [Fe(CN)6]4-. This ion consists of a central iron atom (Fe) surrounded by six cyanide ions (CN-) that act as ligands. The overall charge of the ion is negative, with the cyanide ions providing the negative charge.
How much Cyanide is in sodium cyanide?
The formula of sodium cyanide is NaCN Therefore no. of moles of sample of NaCN is the same as that of the no. of moles of CN- ions
What does it produce if you add Potassium cyanide and water?
It produces potassium and cyanide ions. It is simply dissolution, not an actual reaction KCN --> K+ + CN-
