The chemical reaction between lithium carbonate and aluminum trifluoride produces aluminum carbonate and lithium fluoride:
2AlF3 + 3Li2CO3 → Al2(CO3)3 + 6LiF.

You have an excess of aluminum trifluoride and 1.70 moles of lithium carbonate, which produces 2.98 moles of lithium fluoride. What is the percent yield of the reaction? Use the periodic table and this polyatomic ion resource.

Which of the following observations indicates that an atom has neutrons? some uncharged particles are scattered by a beryllium atom when it hits a gold foil. some uncharged particles bounce back from a gold foil when it is bombarded with alpha particles. a radiation consisting of uncharged particles is emitted when alpha particles strike beryllium atoms. a radiation which attracts electrons is produced when a beryllium atom is bombarded with alpha particles.
