SiO 2 + 3C SiC + 2CO In an experiment, 155 g SiO 2 were reacted with excess C and 72.1 g SiC were recovered. Determine the % yield of SiC.

Which type of bonding involves the complete transfer of a valence electron from a less electrogrative atom to a more electronegative one

Newtons second law deals most cosely with

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
