What was the ratio of Cu 2 to S-2?
The ratio of Cu ions (Cu2+) to sulfide ions (S2-) in copper sulfide (Cu2S) is 1:1, meaning for every Cu2+ ion there is one S2- ion. This results in a 1:1 ratio of Cu2+ to S2-.
Is copper positively charged or negatively charged?
A copper ions has a positive charge, most commonly 2+.
What is the charge for CuO?
Since Oxygen has an ion charge of -2 & Copper has a 2 as a subscript, it means that Copper's ion charge will be +1. Cu2O = Copper (I) Oxide
What is the number of ions in Cu2O?
Three. Two copper +1 ions and one oxygen -2 ion
What is the formula for aqueous copper nitrate?
The formula for aqueous copper nitrate is Cu(NO3)2.
What is the name of the Cu plus ion?
Cu+
What is the chemical formula in copper?
Cu the ion of copper is generally Cu 2+
What is the polyatomic ion in the compound CuCO3?
The Sulfate, SO4
What is the balance equation of cupric ion?
Cu-------Cu2+ + 2 e-
What is the chemical name of Cu Co3?
copper (I) carbonate The carbonate ion has a -2 charge. Since the formula given is Cu2CO3, it indicates there are 2 Cu atoms required to fulfill the carbonate ion's needs. This means the Cu ion must be of the Cu+1 species.
What is the formula for cupric hydroxide?
The formula for cupric hydroxide is Cu(OH)2. It consists of one copper (Cu) ion bonded to two hydroxide (OH) ions.
What is the balanced formula equation for aqueous silver nitrate and copper metal react to produce aqueous copper 2 nitrate and silver metal?
If the reaction includes copper (II): Cu + 2AgNO3 yields 2Ag + Cu(NO3)2 If the reaction includes copper (I): Cu + AgNO3 yields Ag + Cu(NO3) Then spectator ions are dis regarded: 2Ag[ion] + Cu[metal] --> 2Ag[metal] + Cu[2+ ion]
What is the metallic ion in copper II chloride?
The metallic ion in copper II chloride is copper (Cu2+).
What is the oxidation number of cuco3?
The oxidation number of each copper (Cu) atom in CuCO3 is +2. The oxidation number of the oxygen (O) atoms in the carbonate ion (CO3) is -2, and the overall charge of the carbonate ion is -2.
CuSO4 reacts with KCN to give what?
When CuSO4 reacts with KCN, cyanide ion (CN-) replaces sulfate ion (SO4^2-) to form copper cyanide (Cu(CN)2) and potassium sulfate (K2SO4).
What common d-block ion is isoelectronic with Zn2?
The common d-block ion that is isoelectronic with Zn^2+ is Cu^+. Both ions have the same number of electrons, specifically 28.
What is the charge on the metal ion of the salt CuO?
As there are two of them, the charge on the copper ion is 1+ to balance the charge of the oxygen (2-).
