Align columns, last vertical line bug and add row height

Align columns, last vertical line bug and add row height

This is my table:

I have a few problems:
I want both columns to take each 50% of the page width (excl margin), but
the second column's text needs to be aligned right.
The last vertical line is not correctly placed
The first and last row need to be a bit higher so the text fits better.
\begin{tabularx}{\textwidth}{|p{0.5\textwidth}|p{0.5\textwidth}|}
\hline
\textbf & \textbf\\ \hline
\hline
\textbf{Aanwendingsvormen} van het vermogen & \textbf{Vermogensbronnen}\\
\begin{itemize}
\item Bezittingen
\item Vorderingen
\end{itemize}
&
\begin{itemize}
\item Eigen vermogen
\item Vreemd vermogen
\end{itemize}\\
\textbf{Ondernemingsmiddelen} & \textbf{Ondernemingsbronnen}\\
Welke middelen heeft de onderneming om haar activiteit te ontwikkelen? &
Hoe financiert de onderneming de ondernemingsmiddelen.\\
\hline \hline
\textbf{{\Large Vermogen} van de onderneming} & \textbf{{\Large Vermogen}
van de onderneming}\\\hline
\end{tabularx}
I didn't find anything on this, so any help is appreciated!
