Hydrogen fluoride is used in the manufacture of freons (which destroy ozone in the stratosphere) and in the production of aluminum metal. it is prepared by the reaction.
caf2+> caso4+2hf
in one process, 6.25kg of caf2 is treated with an excess of h2so4 and yields 2.35 kg of hf. calculate the percent yield of hf.
(% yield)
2) diethyl ether is produced from ethanol according to the following equation. 2ch3ch2oh(> ch3ch2och3(l)+h2o(l)
calculate the percent yield if 60.0g of ethanol reacts to produce 13.0g of ether % yield?

Many free radicals combine to form molecules that do not contain any unpaired electrons. the driving force for the radical–radical combination reaction is the formation of a new electron‑pair bond. consider the chemical equation. n(g)+no(g)⟶nno(g) n(g)+no(g)⟶nno(g) write lewis formulas for the reactant and product species in the chemical equation. include nonbonding electrons. n(g)n(g) select draw rings more erase select draw rings more erase select draw rings more erase n no(g)
