In your own words list the rules for naming hydrocarbons and substituted hydrocarbons. Be detailed in listing all rules includin
Irina18 [472]

Answer :

The basic rules for naming of hydrocarbons are :

First select the longest possible carbon chain.

The longest possible carbon chain should include the carbons of double or triple bonds.

The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne by adding the suffix -yne.

The numbering is done in such a way that first carbon of double or triple bond gets the lowest number.

The carbon atoms of the double or triple bond get the preference over the other substituents present in the parent chain.

If two or more similar alkyl groups are present in a compound, the prefixes di-, tri-, tetra- and so on are used to specify the number of times of the alkyl groups in the chain.

Which description best fits a gas? definite shape and volume; strong intermolecular attractions definite volume; shape of contai
wolverine [178]

The answer is weak intermolecular attractions volume and shape of container. The molecules of gases have high kinetic energy compared to those of liquids and solids hence they are farther apart from one another. This results to weak intermolecular forces. Gases also expand to fit the container hence have no definite shape or volume.

Why do electrons move from the negative end of the tube to the positive end? ​
satela [25.4K]

Answer: Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.

The molar solubility if Pb(IO3)2 in
lana66690 [7]

Answer:

Ksp = 2.4 * 10^-13

Explanation:

Step 1: Data given

Molarity of NaIO3 = 0.10 M

The molar solubility of Pb(IO3)2 = 2.4 * 10^-11 mol/L

Step 2: The initial concentration

NaIO3 = 0.1M

Na+ = 0 M

2IO3- = 0 M

Step 3: The concentration at the equilibrium

All of the NaIO3 will react (0.1M)

At the equilibrium the concentration of NaIO3 = 0 M

The mol ratio is 1:1:1

The concentration of Na+ and IO3- is 0.1 M

Pb(IO3)2 → Pb^2+ + 2IO3^-

The concentration of Pb(IO3)2 can be written as X

The concentration of Pb^2+ can be written as X

The concentration of 2IO3^- can be written as 2X

Ksp = (Pb^2+)(IO3^-)²

⇒ with (Pb^2+) = 2.4*10^-11

 ⇒ with (IO3^-) = 2x from the Pb(IO3)2 and 0.1M from the NaIO3.

   ⇒The total (IO3^-) = 2x + 0.1 and we assume that x is so small that we can neglect it.

Ksp = (2.4 *10^-11)*(0.1)²

Ksp = 2.4 * 10^-13
