There are several issues here.1. It is better to use the BeginFrame and EndFrame environments (from the environment drop-down list) rather than put the begin and end statements in ERT. In fact, the BeginFrame environment in LyX is tied to a macro that does some extra housekeeping sorts of things, and I'm not 100% sure that putting \begin{frame} in ERT will always work.
2. In the heading of the block, you have \CE{CO2}. It should be \ce{CO2}.
3. Your use of double spacing is causing LaTeX errors. I don't know
why, but I don't think the setspace package is compatible with Beamer.
If you really want to expand the spacing, you can add
\renewcommand{\baselinestretch}{1.2} to the preamble. (I tested this
and it does not seem to cause problems.)
I've attached a modified version of your test file. /Paul
