[Tex/LaTex] How to nicely place two heaps next to each other

nodestikz-pgftikz-trees

I am quite new to latex and I have a question on how to place two heaps of this size nicely next to each other in latex. For example:

\[\begin{tikzpicture}[every node/.style={circle,draw},level 1/.style={sibling distance=30mm},level 2/.style={sibling distance=10mm}]
    \tikzstyle{every node}=[circle,draw]
    \node {7}
           child{node{12}
             child{node{25}} child{node{14}}}
           child{node{9}}
    ;
\end{tikzpicture}\]


\[\begin{tikzpicture}[every node/.style={circle,draw},level 1/.style={sibling distance=30mm},level 2/.style={sibling distance=10mm}]
    \tikzstyle{every node}=[circle,draw]
    \node {7}
           child{node{12}
             child{node{25}} child{node{14}}}
           child{node{9}
             child{node{41}}}
    ;
\end{tikzpicture}\]

A blank line is mark-up for a paragraph break. As you probably know, it is the standard, recommended way to indicate that a new paragraph is required in text. It is no different here.

Moreover, \[...\] puts the contents in display maths mode, which will centre the contents with vertical space above and below.

You don't need to put a tikzpicture in maths mode and it is probably a bad idea. So just don't use \[...\] and remove the blank lines.

\tikzstyle{} is deprecated and, in your examples, is simply repeating settings you've already configured anyway.

To keep formatting of the 'heap's consistent, consider using a TikZ style, set here using \tikzset and named heap:

\documentclass{article}
\usepackage{tikz}
\tikzset{
  heap/.style={
    every node/.style={circle,draw},
    level 1/.style={sibling distance=30mm},
    level 2/.style={sibling distance=10mm}
  }
}
\begin{document}
\begin{tikzpicture}[heap]
  \node {7}
  child{node{12}
    child{node{25}} child{node{14}}}
  child{node{9}}
  ;
\end{tikzpicture}
\begin{tikzpicture}[heap]
  \node {7}
  child{node{12}
    child{node{25}} child{node{14}}}
  child{node{9}
    child{node{41}}}
  ;
\end{tikzpicture}
\end{document}

[Tex/LaTex] TikZ tree sibling distance

Using tikz-qtree helps a bit with automatic spacing of siblings. It also provides a simpler input method. Here's your second tree done in that way:

\documentclass[landscape]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage[margin=1in]{geometry}
\usepackage{tikz-qtree}
\usetikzlibrary{shadows,trees}
\begin{document}
\tikzset{font=\small,
edge from parent fork down,
level distance=1.75cm,
every node/.style=
    {top color=white,
    bottom color=blue!25,
    rectangle,rounded corners,
    minimum height=8mm,
    draw=blue!75,
    very thick,
    drop shadow,
    align=center,
    text depth = 0pt
    },
edge from parent/.style=
    {draw=blue!50,
    thick
    }}

\centering
\begin{tikzpicture}
\Tree [.Paletizador
        [.{Inicialização\\de sistema}
            [.{Sensor X} ]
            [.{Acção Y} ] ] 
        [.Sacos
            [.{Linha/Coluna} 
                [.{Garra} ]
                [.{Rodar Garra} ]
                [.{Acção Y2} ] ]
            [.{Euro Pallet} ]
            [.{Disposição $xyz$}
                [.{$x=?$} ]
                [.{$y=?$} ]
                [.{$z=?$} ] ] ] 
        [.{Sistema de despacho}
            [.{Sensor de peso\\/contador} ]
            [.{Tapete rolante\\de saída} ] ]

[Tex/LaTex] How to define the default vertical distance between nodes

I don't really get the question so I hope this is what you wanted. If you include a full document (such that we copy paste and see the problem on our systems) things are much more easier.

Here, you can change the default setting within a scope but your block style had a node distance which was resetting every time it is issued. I've made it 2mm such that we can see the difference easier.

\documentclass[tikz]{standalone}
\usetikzlibrary{arrows,shapes.geometric,positioning}

\begin{document}
\begin{tikzpicture}[decision/.style={diamond, draw, text width=4.5em, text badly centered, node distance=3.5cm, inner sep=0pt},
                    block/.style   ={rectangle, draw, text width=6em, text centered, rounded corners, minimum height=4em, minimum height=2em},
                    cloud/.style   ={draw, ellipse, minimum height=2em},
                    line/.style    ={draw,-latex'},
                    node distance = 1cm, 
                    auto]
    \node [block] (1st) {1st};
    \node [block, right= of 1st]  (2nd1) {2nd1};
\begin{scope}[node distance=2mm and 10mm]%Here we change it for everything inside this scope
    \node [block, above= of 2nd1] (2nd2) {2nd2};
    \node [block, below= of 2nd1] (2nd3) {2nd3};
    \node [block, right= of 2nd1] (3rd1) {3rd1};
    \node [block, above= of 3rd1] (3rd2) {3rd2};
    \node [block, above= of 3rd2] (3rd3) {3rd3};
\end{scope}
    \node [block, below= of 3rd1] (3rd4) {3rd4};
    \node [block, below= of 3rd4] (3rd5) {3rd5};

    \path [line] (1st) -- (2nd1);
    \path [line] (2nd1) -- (2nd2);
    \path [line] (2nd1) -- (2nd3);
    \path [line] (2nd2) -- (3rd3);
    \path [line] (2nd1) -- (3rd1);
    \path [line] (1st) -- (2nd1);
\end{tikzpicture}
\end{document}
