Significats de sulphur trioxide en anglès

It is therefore analogous to sulphur trioxide which forms sulphuric acid in a similar way:

Sulphuric acid converts it into ethyl sulphuric acid (see ETHER, and sulphur trioxide gives carbyl sulphate.

It is not decomposed at a red heat but suffers loss, probably of sulphur trioxide, at a temperature above 900°C.]

Reactions involving sulphur dioxide, sulphur trioxide, and sulphuric acid can channel energy reasonably efficiently: Earth's use of free oxygen is only twice as effective.
