The cardboard sleeves reduce the heatness from the coffee cup. So then the cosumer does not get a burn.
Limestone (CaCO₃) is the second most abundant mineral on Earth after SiO₂. For many uses, it is first decomposed thermally to quicklime (CaO). MgO is prepared similarly from MgCO₃.
AT 871°C CaCO 3 needs about 1 hour for complete decomposition.
<h3>
At what temperature Caco3 decompose to Cao?</h3>
At any temperature higher than 835°C, the value of Δ G ∘ will be negative and the decomposition reaction will be spontaneous.
AT 871°C CaCO 3 needs about 1 hour for complete decomposition.
Calcium carbonate decomposes on heating to give calcium oxide and carbon dioxide.

Ok well whats the questions
Friedel-Crafts alkylation requires dry conditions because AlCl3 may combine with water thereby hindering the reaction.
Friedel-Crafts involves the introduction of an alkyl group into a benzene ring. This occurs by electrophilic substitution of a proton on the aromatic ring with an alkyl group.
The set up must be free from water because water could inactivate the Lewis acid (AlCl3) due to combination of the Lewis acid with water thereby hindering the reaction.
