NO3 is the spectator. It is always a spectator ion, because all nitrates are water soluble.

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.
What is the difference between magnesium oxide and magniesum sulfate?
Magnesium sulfide is a simple salt, MgS. Sulphate is a polyatomic ion with a formula SO <sub>4</sub>, therefore, the formula for Magnesium sulfate would be MgSO<sub>4</sub>

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.
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)
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
