Magnesium metal reacts with solid boron oxide (B203) to form elemental boron and
magnesium oxide, which are both solids.
What is the coefficient of boron in the
balanced chemical equation for the reaction?
(Balance the equation with the smallest possible whole mimber coefficients.)

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

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

catya your not at all which answer i've seen you do this on another question!

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
