Silver Tarnish and Reactivity Series
I read that silver in the presence of hydrogen sulfide corrodes to form silver sulfide and hydrogen.
$$\ce{Ag + H2S -> Ag2S + H2}$$
But in the reactivity series silver is placed much below hydrogen....

Can you oxidize gold using only oxygen?
I keep reading that gold does not react with oxygen, but I also see information about gold Oxides (ie: aurous oxide, Au2O and auric oxide, Au2O3)
Knowing that there is a way of getting gold oxide ...

Are there stronger oxidizing agents than fluorine gas?
Are there stronger oxidizing agents than fluorine gas, so it could oxidize fluoride to fluorine?
Also, in case of oxygen, fluorine gas can oxidize oxygen gas to the exotic dioxygenyl ion. Can ...

What drives double displacement reactions?
I have two questions:
I understand that in a displacement reaction the more reactive element displace the less reactive element. But why? In the reaction with Zinc and Copper Sulfate, we form Copper ...

Can metal displacement reactions happen with insoluable salts?
I know how normal metal displacement reactions work. If one metal is more reactive than the other, they will displace.
For example, normally for this reaction:
$$\ce{Fe_{(s)} + 2AgCl_{(aq)} -> Fe^{+...

Why doesn't XeF6 displace oxygen from water?
Consider the following reactions (unbalanced):
$$
\begin{align}
\ce{XeF2 + H2O &→ Xe + HF + O2} \tag{a} \\
\ce{XeF4 + H2O &→ XeO3 + Xe + O2 + HF} \tag{b} \\
\ce{XeF6 + H2O &→ XeO3 + HF} \...

Why do bubbles form when a reactive metal is placed in a less reactive metal's salt solution?
What is the gas that if formed when a reactive metal is placed in a salt solution of a less reactive metal? Theoretically, it should just be a simple displacement.
I know that this question has been ...

Does chlorine trifluoride react with candlewax?
I've run across references to chlorine trifluoride quite a lot. It pops up fairly regularly on the Worldbuilding SE, and whatever idea people have with it is usually shot down very quickly - For ...

Reaction of aqueous sodium carbonate with aluminum foil
Aqueous sodium hydroxide is known to react with aluminum foil in an exothermic, hydrogen-gas releasing reaction like $$\ce{2NaOH(aq) + 2Al(s) + 2H2O(\ell) → 2NaAlO2(aq) + 3H2(g)}$$
However, on ...

Equation for reaction between chlorine fluoride and potassium bromide
The equation given in the answer key was
$$\ce{ClF + 2KBr → KCl + KF + Br2}$$
However won't the $\ce{KCl}$ also react with $\ce{ClF}$ to form $\ce{KF}$ and $\ce{Cl2}$, resulting in the net reaction ...

How can the iron in the reaction of iron (ii) chloride and zinc not go to zero oxidation state?
I know that the zinc half equation would be
$\ce{Zn -> Zn^{2+} + 2e-}$.
However I am confused about the half equation for iron. I would think that since iron is completely displaced, its oxidation ...
