Answer 2

Answer:

hi good afternoon are you an ARMY? I am too.

Explanation:

Ethanol can be dehydrated to give ethene by heating it with an excess of concerntrared sulphuric acid at about 170°C. Concerntrared phosphoric (V) acid, H3PO4, can be used instead. The acids aren't written into equation because they serve as catalysts.
