\begin{remark} \begin{remark}
$i$ is often not injective and $\Ker(i) = \{r \in R | \exists s \in S ~ s \cdot r = 0\} $. $i$ is often not injective and $\ker(i) = \{r \in R | \exists s \in S ~ s \cdot r = 0\} $.
In particular $(r = 1)$, $R_S$ is the null ring iff $0 \in S$. In particular $(r = 1)$, $R_S$ is the null ring iff $0 \in S$.
