A crystallographer measures the horizontal spacing between molecules in a crystal. The spacing is 10.59 nm . What is the total w
Readme [11.4K]
Whenever objects are placed in a line with spaced in between them, the number of spaces is one less than the number of objects. For reference, you may hold up four fingers and count the spaced between your fingers.

Therefore, if there are 105 molecules, then there are 104 spaces present.

We also know that 1 mm = 1000 nm. So, we first convert the spacing to millimeters as the final answer is required in millimeters

spacing = 10.59/1000 = 0.01059 mm

Now, the width of the lattice will be (ignoring the size of the molecules):

104 * 0.01059

1.10 millimeters

Key terms: Reset Compounds that contain a carbon-carbon double bond are known as ____________ . Alkenes are electron rich; there
Damm [24]

Answer: Compounds that contain a carbon-carbon double bond are known as _____alkenes_______ . Alkenes are electron rich; therefore, simple alkenes do not react with _____nuceophiles_______ or bases, but will react with _____electrophiles_______ or acids. In the IUPAC system, an alkene is identified by the suffix _____-ene_______ . Addition reactions in which two parts of a reagent are added to the same side of a double bond are known as _____syn_______ additions. Addition reactions in which two parts of a reagent are added from opposite sides of a double bond are called _____anti_______ additions. Halogenation and halohydrin formation occur with _____anti_______ addition. Hydroboration occurs with _____syn_______ addition.

Explanation:

The right terms have been filled into the statement.

Electrophiles are election rich so they react with nucleophiles. And vice versa.

Addition reactions in which two parts of a reagent are added to the same side of a double bond are known as _syn reaction and that involving opposite is anti reaction.

The Halohydrin formation reaction involves breaking a pi bond and creating a halohydrin in its place. Halo = halogen and Hydrin = OH. This reaction takes place in water and yields an anti-addition reaction which follows Markovnikov's rule.
