What is the oxidation number cucl2?
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.
Can compound undergo chemical change to become elements how?
Yes. Compounds can undergo chemical changes to become elements. An example would be the following: Zn(s) + CuCl2(aq) ===> ZnCl2(aq) + Cu(s). THe CuCl2 is a compound and it is changed into the element Cu(s) and also into zinc chloride.
Is it true an ionic compound is written by using the highest ratios of the ions in the compound?
Yes, in an ionic compound, the formula is written using the lowest whole-number ratio of the ions present in the compound. This is done to achieve overall charge neutrality by balancing the charges of the cations and anions.
What formula for a compound has a ratio between positive and negative ions that is one to two?
but I also need the sum of the atomic numbers for the two elements involved in the polyatomic ion to be 13.
What volume of 0.176M Na3PO4 solution is necessary to completely react with 91.3mL of 0.115M CuCl2?
To determine the volume of the Na3PO4 solution needed for complete reaction, we would first write a balanced chemical equation for the reaction between Na3PO4 and CuCl2. Then, use the molarity of CuCl2 and the stoichiometry of the reaction to calculate the volume of Na3PO4 required.
What is the oxidation number cucl2?
Oxidation number is the charge per atom in a compound. Cl2= 2- (Cl= 1-) Cu would have to be 2+ to balance the compound, because there is only one copper atom.
What is a written portrait?
a written portrait is when you wright about a picture. for example describe was u see or would smell.
What would result from the addition pof copper metal to alcl3?
CuCl2 and Al(s)
How do you write 75 percent of a number?
You write a number, not wright! It would be written as 75% of [the number].
State the order in which the ions associated with a compound composed of potassium and bromine would be written in the chemical formula and the compound name?
In the chemical formula, the cation (potassium) would be written first followed by the anion (bromine). Therefore, the compound would be named potassium bromide.
The compound CuCl2 is named copperII chloride explain why a roman numeral is used in one name but not the other?
In the chemical formula CuCl2 it is obvious for a neutral ionic substance that copper has a +2 charge, since Cl only comes in -1 charge, but in the stock name of copper chloride, it is unclear whether it is CuCl2 you are talking about or CuCl, which has a +1 Copper, thus in the name, the charge of the metal is differentiated by the roman numeral in parenthesis after the metal. This stock system (using numerals) is much easier to read than the previous traditional system of naming the higher charge metal with the -ic ending and the lower charged metal with the -ous ending, where CuCl2 and CuCl would be cupric chloride and cuprous chloride, respectively.
Can compound undergo chemical change to become elements how?
Yes. Compounds can undergo chemical changes to become elements. An example would be the following: Zn(s) + CuCl2(aq) ===> ZnCl2(aq) + Cu(s). THe CuCl2 is a compound and it is changed into the element Cu(s) and also into zinc chloride.
What is Wright Phillips surname?
It would be Wright-Phillips, actually.

To name the compound written as cuci2 would write what?
The compound written as CuCl₂ is named copper(II) chloride. The "Cu" represents copper, and the "Cl₂" indicates there are two chloride ions. The Roman numeral II indicates that copper has a +2 oxidation state in this compound.
What formula for a compound has a ratio between positive and negative ions that is one to two?
