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
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.
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.
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?
To determine which reactant will be used up first, we need to compare the stoichiometric ratio between ZnS and O2. From the balanced equation, we see that 2 moles of ZnS react with 3 moles of O2. Therefore, 1.72 mol of ZnS will require (3/2)*1.72 = 2.58 mol of O2 for complete reaction. Since we have only 3.04 mol of O2, O2 will be the limiting reactant and will be used up first.
