What is the balance equation for the reactions of 1) Manganese (IV) oxide and Hydrogen Peroxide.?

Question

2) Zinc (metal) and Aqueous Hydrochloric acid.

Answer 1

1. 2H2O2 -----> 2H2O + O2

2. Zn + 2HCl -----> ZnCl2 + H2

The catalyst MnO2 does not appear in the first equation because it is not used up.

Answer 2

it extremely is a double displacement reaction. So it fairly is like AB + CD --> advert + CB via way of actuality the final product is HOH you are able to tell that it extremely is like CB indoors the formula I gave you. So the 1st product could desire to be CaCO3. i'm uncertain if it extremely is balanced or now not. With all double displacement reactions you % to earnings even with if a reaction actual have been given right here approximately. via way of that I propose interior the adventure that your products are the two aqueous, then a reaction did now not ensue. you are able to tell a reaction have been given right here approximately it your one or the two actual one in each and every of your products are a solid, liquid or gas. via way of actuality your very final product is a liquid, you do now not could choose to rigidity approximately checking the certainly state of the 1st product. Now which you have your first product all you are able to choose to do is stability it! stable fulfillment and that i'm hoping I helped!

Answer 3

As far as I know, MnO₂ is only a catalyst, so 2H₂O₂ -> 2H₂O + O₂

Zn + 2H+ -> Zn²+ + H₂
(General chemistry teachers will probably have you write it like Gervald F did, but an advanced inorganic prof would insist on the more accurate ionic equation.)

Answer 4

MnO2 + H2O2 = > 2 H20 + something else

Answer 5

Na2SO4 + BaCl2
