i think that equation is balanced, there are the same numbers of each element on each side, unless I am just too sleepy to count properly. Hope this answers your question 2ZnCO3------- 2ZnO 2CO2
2Zn + O2 --> 2ZnO
It is balanced.
Unbalanced CH4 + O2 = H2O + CO2 Balanced CH4 + 2O2 = 2H20 + CO2
2koh+co2--k2co3+h2o
The balanced equation is 2 C4H10 + 13 O2 -> 8 CO2 + 10 H2O.
ZnCO3, when heated in the absence of air, decomposes to give ZnO and CO2. I think this is the answer.
The Question's last part is not precisely stated, but an answer could be something like this:ZnCO3 ==> ZnO + CO2 ................followed by:2 ZnO + C ==> 2 Zn + CO2 ..........giving the overall reaction:2 ZnCO3 + C 2 Zn + 3 CO2 ..in which ZnO is balanced out.
Yes, but better balancing the equation for DIoxide:2 ZnO + C 2 Zn + CO2
The balanced reaction for the decomposition of zinc oxalate dihydrate to zinc oxide water and carbon dioxide is ZnCO3 --------> ZnO + CO2.
The carbonates that can be thermally decomposed . They form metal oxides and carbon dioxide. When white zinc carbonate powder when heated forms yellow/white zinc oxide and carbon dioxide gas: the balanced equation for zinc carbonate--------carbon dioxide zinc oxide is :ZnCO3 → ZnO + CO2
thermaldecompositionMetal Carbonate ----------> Metal Oxide + Carbon dioxide
ZnCO3 --------> ZnO + CO2.It is an example of decomposition reaction.Colour of zinc oxide produced is yellow when hot and white when cold.
Smithsonite (ZnCO3) , Sphalerite (ZnS), Willemite (Zn2SiO4), Zincite (ZnO)
125 g of Zinc Carbonate is 1 mole and when it decomposes it forms 1 mole of Carbon Dioxide ZnCO3 = ZnO + CO2 1 mole of carbon dioxide has a mass of 44g 44g is the answer
ZnCO3 + 2HCl = ZnCl2 + H2O +CO2
Zinc carbonate decompose in ZnO and CO2.
Zinc + Hydrochloric acid --> Zinc chloride + Hydrogen gas Zn + 2 HCl --> ZnCl2 + H2 + Heat
