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 ...

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} \...

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....

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 ...

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 ...
