For some oxidation reactions Lead(IV) oxide can be used in place of Manganese dioxide
When manganese dioxide is heated with aluminium powder, the following reaction takes place: These displacement reactions are highly exothermic. The amount of heat evolved is so large that the metals are produced in the molten state. On the other hand when manganese is heated with aluminum oxide no reaction takes place as aluminum is more reactive than manganese and is placed higher in the activity series.
It is possible for carbon dioxide and copper oxide to encourage a reaction to take place due to thermal composition. When calcium carbonate is heated, it decomposes and generates carbon dioxide and copper oxide.

Sulfur dioxide is the most common oxide of sulfur, so we'll use that in our example. 2SO2 + 2H2O + O2 in the presence of nitrogen dioxide (NO2) and sunlight gives 2H2SO4. In short, the more sulfur dioxide, the more sulfuric acid. Sulfuric acid is a good product in its place, and that place isn't in raindrops.
H2O2, or Hydrogen Peroxide is combined with MnO2, Manganese Dioxide, to form H2O, water, and O2, oxygen gas. The Manganese Dioxide serves as a catalyst in this reactions since it is not a reactant, but sets the reaction in motion. Therefore, when writing the chemical equation, one should place MnO2 beneath the yield sign. One's balanced chemical equation should look like this: a. 2H2O2(L) ==> 2H2O(L) + O2(g) MnO2(s)
a redox reaction takes place ( one gains oxygen and the other looses oxygen) the zinc (oxide) is displaced and the iron becomes iron oxide and zinc oxide becomes zinc
Chemical bounding takes place when one different type of atom combines or reacts wth an other different type of atom to create a chemical reaction. for example iron oxide reacts with carbon to get iron + carbon dioxide
Decomposition reaction(of Lead(II) nitrate) takes place. It decomposes into Yellow Lead(II) oxide, Reddish-orange Nitrogen dioxide and Oxygen
The four main greenhouse gases are ozone, carbon dioxide, methane, and nitrous oxide. These gases are said to responsible for the world wide climate change taking place now.
magnesium oxide is made up of two elements magnesium & oxygen..
In the past, manganese was erroneously located.
because the gas exchange takes place in the lungs, so the carbon-dioxide and the other gases fro our blood get exchanged with oxygen
