It is because both of them belong to the same group and have only 2 electrons in their valence shell.Therefore, they tend to loose them in order to attain stable electronic configuration.Doing this they form +2 charged ions.
To find the oxidation number of zinc (Zn) in zinc nitrate (Zn(NO3)2), you start by recognizing that nitrate (NO3) has a charge of -1. Since there are two nitrate ions in the compound, the total negative charge is -2. To balance this, the oxidation number of zinc must be +2. Therefore, the oxidation number of Zn in Zn(NO3)2 is +2.
the charge of zinc has only one charge which is 2+.
The reaction equation between Zn^2+ and EDTA is: Zn^2+ + EDTA → Zn(EDTA)^2-
Zn(NO3)2 + 2Ag ---> Zn + 2AgNO3
yes Zn + 2HCl -> ZnCl2 + H2 is balanced
Zn will most likely get a 2+ (positive) charge!
The oxidation number of Zn in the complex ion Zn(OH)4 2- is +2. This is because the overall charge of the complex ion is -2, and each hydroxide ion (OH-) has a -1 charge. Hence, the zinc (Zn) ion must have a +2 charge to balance the overall charge of the complex ion.
Zinc is Zn; bicarbonate, also known as hydrogen carbonate, is HCO3; after taking into account the +2 charge of the Zn and the -1 charge of HCO3 we get: Zn(HCO3)2.
The charge of the Zn ion is typically 2+ or 2. This is because zinc typically loses two electrons to achieve a stable electron configuration.
To find the oxidation number of zinc (Zn) in zinc nitrate (Zn(NO3)2), you start by recognizing that nitrate (NO3) has a charge of -1. Since there are two nitrate ions in the compound, the total negative charge is -2. To balance this, the oxidation number of zinc must be +2. Therefore, the oxidation number of Zn in Zn(NO3)2 is +2.
Equation is Zn + Pb(NO3)2 --> Zn(NO3)2 + Pb
the charge of zinc has only one charge which is 2+.
The reaction equation between Zn^2+ and EDTA is: Zn^2+ + EDTA → Zn(EDTA)^2-
Zn(NO3)2 + 2Ag ---> Zn + 2AgNO3
yes Zn + 2HCl -> ZnCl2 + H2 is balanced
Your question is not clear: the mass of products is equal to the mass reactants.
The oxidation number of zinc (Zn) in Zn(NO3)2 is +2, while in Zn(OH)4^2-, it is also +2. Therefore, there is no change in the oxidation number of zinc.
