Achemistry student needs 55.0g of carbon tetrachloride for an experiment. by consulting the crc handbook of chemistry and physics, the student discovers that the density of carbon tetrachloride is 1.59·gcm−3 . calculate the volume of carbon tetrachloride the student should pour out.

The characteristics of two different types of reactions are shown below: reaction a: electrons are gained by the atoms of an element. reaction b: protons are lost by the atom of an element. which statement is true about the atoms of the elements that participate in the two reactions? their identity changes in both reaction a and reaction b. their identity changes in reaction a but not in reaction b. their identity changes in reaction b but not in reaction a. their identity remains the same in both reaction a and reaction b.
