Copper has a density 0f 8.96 g/cm3. Determine the volume of a piece of copper with mass of 10.56 g.
(this is what I need the answer to) If the piece of copper is a wire with a length of 125.5 cm, what is its diameter?
This is all the information I received.

if you're asking what comes out, it's steam.

frequency, z, and the collision density, z, in carbon dioxide (co2), r 180 pm at 30 °c and 120 kpa

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
