Hydrogen sulfide

Hydrogen sulfide (formula: H2S) is a chemical compound which occurs as a colourless gas with acidic properties. Its characteristic odor, which resembles that of rotten eggs makes the identification of the compound easy. 

It is present in the atmosphere (in low concetrations, less than 0.0003ppm) and also works as a signaling molecule for many animals, including humans. Its odor can be identified at concentrations of around 0.1 to 0.15ppm. As the concentration increases, it obtains a sweet odor and becomes deadly.

It's corrosive and flammable.

Last time I annoy you. I saw there was a typo on the title. There are two ways to handle that:

* inferior: mark article with bad ID as not visible on metadata, copy it over to good title
* superior: using synonym renaming: https://docs.ourbigbook.com/ourbigbook-web-page-renaming which gives you redirects from old to new

We really want to add a simple on click web UI way to make synonym renaming without typing.


Last tip: hiding and renaming articles

One of the key features of ourbigbook is that everything in the tree is unscoped by default. E.g. the "Overview" article actually goes under https://ourbigbook.com/pioyi/oveview and not https://ourbigbook.com/pioyi/hydrogen-sulfide/overview as you likely wanted.

The reason for that is that this is the best way to make topics work: https://docs.ourbigbook.com/#ourbigbook-web-topics and topics is basically the only feature that justifies the project.

There are two solutions to model your knowledge:

1) (recommended in this case: make a longer more specific title "Overview of Hydrogen Sulfide" or "Hydrogen sulfied overview"

2) Use scopes. Locally the tree would look like this: https://docs.ourbigbook.com/#h-scope-argument

```
= Hydrogen sulfide
{scope}

== Overview

== Production
{scope}

=== Laboratory

=== Industrial
```

which would produce a tree structure as:

```
/hydrogen-sulfide
/hydrogen-sulfide/overview
/hydrogen-sulfide/production
/hydrogen-sulfide/production/laboratory
/hydrogen-sulfide/production/industrial

```

I should also note that I'm not sure if scopes are working perfectly via web UI, though if they are not I want them to.

One big reason I don't recommend scopes in this case is that there is currently no way to unscope things. What if later on you want to add a child of "Hydrogen sulfide" but you don't want for its url to be `/hydrogen-sulfide/something`? It's not currently possible. Though I would like to support it one day.

I would also just remove the Overview section and just dump its contents on "Hydrogen sulfide" itself, since the content of an article is basically always its own overview.

I would recommed using scopes only very sparsely when you go into extremelly specific tutorials about something, which are very unlikely to have topic hits by others, e.g. https://ourbigbook.com/cirosantilli/cia-2010-covert-communication-websites though even then I end up regretting it.

Anyways we'll see, maybe at some point people will prever to use just scopes and we'll go there more.
