It most certainly isn't, not in Spain, nor in the US or most other democracies.

Separation of powers:

- Legislative (parliament, congress, senate, house of ..., many names - in Spain I think they call it Cortes Generales and it consists of two chambers, a senate and a congress)

- Executive (government)

- Judicial (courts)

This is wrong for the US, but I don't know the Spanish government structure enough to weigh in there.

The US Government is split into three branches, like you mentioned (Legislative, Executive, Judicial). Those three branches are the government. You are erroneously equating government to mean exclusively the executive branch of the government though.
