Balancing: sodium carbonate solid combines with silver iodide liquid to form silver carbonate solid and sodium iodide liquid.

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
