Sorry, with sum formulas, it is impossible to give an answer. Write down the names of the two compounds.


I saw you asked in another forum alredy. You want to combine Acteic anhydrid and Morphin, this gives Heroin.

We dont discuss to make drug here.

You can calculate the mole of HCl and also the mole of the mixture MeO correspond.
A Mixed molare mass as well, but then I think more Information is needed.

The difference of mass of mixture and total sodium chloride gives mass of oxygen. The volume can be calculated with ideal gas law. The mole of the oxygen refers to the mole of sodium chlorate and also the mass of it. The difference of mixture and sodium chlorate gives mass of sodium chloride before....

Ok Buddy. Iron is able to have different oxidation numbers. Basically + 2 and +3 In the First experiment iron goes from 0 to +2 by adding an acid in this case acetic acid (vinegar). Fe + 2 H+ => Fe2+ + H2 In the second test he add peroxide an oxidizer The oxidation number change from +2 to + 3. 2 Fe...

I dont know what you mean, but it is immpossible to make a aluminium-steel alloy. Aluminiumalloys with other elements anyway are very seldeom.

No it means you have to dissolve the compound in water first. If it is a powder and dry no reaction will take place, only both are dissolved in water and then mixed the reaction will happen.

It is a combination reaction.

Normally 2 SiH4 + N2O => Si2N2O + 4 H2

But without ammonia the reaction doesnt work.

Do you have chemical knowlwdge?
On left side Na is 0
K +1
N +5
O -2

On right side
K +1
O -2
Na +1
N 0

It is called a redox reaction. Nitrogen change from + 5 to 0
Sodium from 0 to +1

That you have to know, which compound you mean. But I think no need to mix it with bleach.
Probably more chlorination will take place.
