1. balance this reaction: fe2o3(s) + c(s) → fe(s) + co2(g) when 4.0 moles of c react with an excess of iron(iii) oxide, how many moles of co2(g) will be produced? 2. for the reaction listed in question 1 (above) how many moles of carbon are needed to completely react with 14.0 moles of iron(iii) oxide?

What three things determine the shape and size of a puddle when water is poured out onto a surface

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.
