Tetraboron carbide, B4C, is a very hard substance used for grinding purposes, ceramics, and armor plating. Because boron is an efficient absorber of neutrons, B4C is also used as a protective material in nuclear reactors. The reaction that forms B4C from boron(III) oxide, B2O3, is
2 B2O3 + 7 C → B4C + 6 CO (at 2400°C)

lol idk man i guess u gotta ask bill nye the science guy

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?

since electrons are negative the answer is neagtaive
