A 3.25 gram sample of solid calcium carbide (CaC2) reacts with water to produce acetylene gas (C2H2) and aqueous calcium hydroxide. If the acetylene was collected over water at 17ºC and 98.66 kPa, what volume of acetylene was produced? CaC2 + 2H2O C2H2 + Ca(OH)2

The answer is b electromagnetic i believe, i hope i ya out!

13 protons and 14 neutrons.  this also means that the amount of electrons also is 13 because electrons have the same amount as protons..the atomic number means the amount of protons (which effectively tells you the electrons) the atomic mass, tells you the amount of protons and neutrons in the nucleus.hope this .
