Put all of C into a boiling tube and heat until a change is noticed. Allow to cool.
Add about 5cm' of HNO, to the residue in the boiling tube and heat to
dissolve the residue.
what is the observation and inference if sample C is CuCO3​

Water (2510 g ) is heated until it just begins to boil. if the water absorbs 5.09×105 j of heat in the process, what was the initial temperature of the water?

An object becomes electrically charged when: electrons are created in it electrons from it are destroyed electrons are transferred to it protons from it are destroyed protons are created in it

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.
