What are the reactants 2ZnS plus 3O2 equals 2ZnO plus 2SO2?
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 i write a balanced equation for zinc oxide?
2ZnO
What is the balanced equation for Zn plus O2?
The balanced equation for the reaction between zinc (Zn) and oxygen (O2) is: 2Zn + O2 -> 2ZnO
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 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
Zinc plus oxygen equals?
Zinc reacts with oxygen to form zinc oxide. The chemical equation is: 2Zn + O2 → 2ZnO.
What compound is made oxygen and zinc?
The compound made from the elements Zinc and oxygen is zinc oxide. The chemical equation is 2Zn + O2 = 2ZnO .
What happens when zinc burns in oxygen?
When zinc burns in oxygen, it forms zinc oxide. This reaction is exothermic and produces heat and light. The chemical equation for this reaction is: 2Zn + O2 → 2ZnO.
What is the balance equation for zinc metal plus oxygen gas?
Zn+ H2O ---> ZnO + H2 Zn+ H2O ---> ZnO + H2
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.
What is the chemical equation for burning Zinc?
Zinc+oxygen----> zincoxide
