The reactants are the substances that are doing the reacting to produce the result. (The substances on the left side of the equation are the reactants)
So ZnS & O2 are the reactants.

How do you balance ZnS plus O2 equals ZnO plus SO2?
2ZnS + 3O2 = 2ZnO + 2SO2
How many grams of ZnO will be formed from the equation 2ZnS plus 3o2 - 2ZnO plus 2SO2?
It depends how much the raw ingredients weighed at the start of the experiment !
What is the balanced equation of zinc oxide and sulphuric acid?
Sulfur dioxide has the chemical formulaSO2Each sulfur atom (S) unites with one oxygen molecule (O2)Thus, S +O2 ---> 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
What reaction would Zn S be?
2ZnS + 3O2 ---> 2ZnO + 2SO2 Zinc sulphide + Oxygen ---> Zinc oxide + Sulphur dioxide This reaction is endothermic and requires a heat change (H) in order to happen. As the Zinc sulphide reacts with the oxygen the zinc becomes oxidised (oxidation, zinc atoms bond to oxygen atoms), and during this reaction sulphur dioxide is given off.
