Calculate the mass of carbon dioxide produced when 150 cm^3 of 1.00 mol dm^-3 hydrochloric acid, hcl(aq), is added to 10.0g of calcium carbonate, caco3

H2so4(aq) + mg(s)—> mgso4(aq) +h2(g) which substance is the acid in the reaction?

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.
