A saturated aqueous solution of urea also contains a significant amount of dissolved carbon dioxide (that is, it is carbonated). what is likely to happen if the solution is cooled?

The answer would be some solid urea will precipitate out of solution. Precipitation responses happen when cations and anions in fluid arrangement join to frame an insoluble ionic strong called precipitate. Regardless of whether such a response happens can be dictated by utilizing the dissolvability rules for normal ionic solids.
