From where did you derive the empirical formula C12H22O12? The empirical formula (and molecular formula) of sucrose is C12H22O11. This has been determined by precise analysis and the molecular structure of sucrose.
@TwilightSparkle2015 Thanks so much!
your welcome can you help me
sure what do you need help with
An oil skimmer is a machine used to separate a mixture of oil and water. After an oil spill in a body of water, skimmers are used to remove the floating oil from the water. Which property is being used to separate oil and water in this way? A.boiling point B.melting point C.chemical reactivity D.density
I think its D.density because the oil floats because of its lower density
@TwilightSparkle2015 I hope that helped:)
OH MY GOD ITS RIGHT

Which of the following statements is false? A.Two or more different substances combine physically to form a mixture. B.Two or more different atoms combine chemically to form an element. C.Two or more atoms combine chemically to form a molecule. D.Two or more elements combine chemically to form a compound.
i believe its B
Yup. B is False.
What defines a mixture? cannot be broken down into simpler substances created through a chemical reaction described by a chemical formula can be broken down into its basic substances through physical means
