What is the balanced equation for Zn Ag2S?
The balanced equation for the reaction between zinc (Zn) and silver sulfide (Ag2S) is: Zn + Ag2S -> ZnS + 2Ag
How do you balance ZnS plus O2 equals ZnO plus SO2?
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.
Heating zinc sulfide in the prescence of oxygen yields th following 2zns 3o2---2zno 2so2 if 1.72 mol of zns is heated in the prescence of 3.04 mol of o2 which reactant will be used up first?
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
How many milliliters of hydrochloric acid are needed to react with 56.5g of zinc sulfide?
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.
Is ZnS ionic or covalent?
Zinc sulfide is a covalent compound.
What are the spectator ions in Mgs Zn2 2NO3- Mg2 2NO3- Zns?
NO3-
What is the reduction half-reaction for Mgs ZnCl2aq MgCl2aq Zns?
Zn^2+ + 2e- ––> Zn(s)
Is ZnS a ionic crystal?
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.
Is ZnS an acid base salt or none?
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.
What is the half-reaction for Mgs ZnCl2aq----------- MgCl2aq Zns?
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.
How many sulfur ions are joined to each zinc ions in the compound zinc sulfide?
The chemical formula of zinc sulfide is ZnS - one sulfur atom.
Is ZnS souble or insoluble in water?
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.
Does ZnS contain a polar covalent bond?
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.
What is the net ionic equation of Mgs Z2 2NO3 Mg2 2NO3 Zns?
Mg(s) + Zn(NO3)2 (aq) ---> Mg(NO3)2 (aq) + Zn(s)
When was ZNS-TV created?
ZNS-TV was created in 1977.
What is the name of ionic compound ZnS?
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
When was ZNS - performer - born?
ZNS - performer - was born on 1989-08-04.
