What mass in grams of the magnetic oxide of iron (Fe3O4) can be made from 23.0 g of pure iron and an excess of oxygen?

The equation is Fe+O2→Fe3O4 (not balanced)
Express the mass to three significant figures and include the appropriate units.

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
