NO3 is the spectator. It is always a spectator ion, because all nitrates are water soluble.
The balanced equation for the reaction between zinc (Zn) and silver sulfide (Ag2S) is: Zn + Ag2S -> ZnS + 2Ag
To balance the chemical equation ZnS + O2 = ZnO + SO2, you need to make sure that the number of each type of atom is the same on both sides of the equation. Start by adding coefficients to the compounds; in this case, a coefficient of 2 in front of ZnS and SO2 balances the equation: 2 ZnS + 3 O2 = 2 ZnO + 2 SO2.
The equation that you need is 2ZnS + 3O2 ======> 2ZnO + 2SO2The equation is a 2 to 3 molar. The coefficients in the equation tell you how many moles of each reactant you need. So as the equation is 2ZnS + 3O2 that means 2 moles of ZnS is needed to react with 3 moles of O2. Since the question gives you 1.72 moles of ZnS and 3.04 moles of O2 the ZnS will run out first as 1.72 divided by 2 is 0.86 and 3.04 divided by 3 is 1.0133333... therefore we have less ZnS
ZnS + 2 HCl --> Zn2+ + 2Cl- + (H2S)gasBe careful!Almost 13 Litre of very toxic (or poisonous and stinky) hydrogen sulfide gas (H2S) will be produced. Only to be performed in absolutely approved and controlled laboratory conditions with a alkaline gas scrubber! Remember: H2S is already poisonous when you can't even smell it.(Its MAC-dose concentration is lower than its odour threshold)Stoiciometric Calculus:56.5 (g ZnS) / 97.474 (g/mol ZnS) = 0.5796 mol ZnS == 0.5796 (mol ZnS) * (2 mol HCl / mol ZnS) = 1.16 mol HClHow many Millilitres you'll need depends on the concentration HCl (in mol/L = mmol/ml ):1.16*103 (mmol HCl) / (concentration HCl) = (1.16*103 / c) ml HCl.This is a single disposition reaction.
Zinc sulfide is a covalent compound.
NO3-
Zn^2+ + 2e- ––> Zn(s)
ZnS is a covalent crystal. Although composed of positively charged zinc ions and negatively charged sulfur ions, the bonding within ZnS is primarily covalent due to the sharing of electron pairs between the zinc and sulfur atoms.
ZnS is a salt composed of zinc and sulfur, so it is neither an acid nor a base. It does not produce H+ or OH- ions in solution like acids or bases do.
The half-reaction for this redox reaction could be written as: Zn(s) -> Zn2+(aq) + 2e-. This indicates the oxidation of solid zinc (Zn) to zinc ions (Zn2+) and the release of 2 electrons.
The chemical formula of zinc sulfide is ZnS - one sulfur atom.
ZnS is insoluble in water because it forms a sparingly soluble compound due to the strong bond between zinc and sulfur ions. Only a very small amount of ZnS can dissolve in water to form a solution.
No, zinc sulfide (ZnS) does not contain a polar covalent bond. The bond between zinc and sulfur in ZnS is ionic in nature, with zinc losing its electrons to sulfur resulting in the formation of charged ions.
Mg(s) + Zn(NO3)2 (aq) ---> Mg(NO3)2 (aq) + Zn(s)
ZNS-TV was created in 1977.
ZnS is correct for Zinc Sulphide (I refuse to spell sulphur with an f) - Zn likes to form +2 ions losing the 2 4s electrons to form the +2 oxidation state, and S likes to either form -2 or +6 oxidation states, thus forming ZnS
ZNS - performer - was born on 1989-08-04.
