use the rock records on page 1 to complete the questions below.

1. examine record a. use the three basic rules to figure out the ages of the layers. in chart a, list the layers from youngest to oldest with the youngest layer in the first row.

2. look for signs of tilting, erosion, or folding. in the second column in chart a, write whether you think tilting, erosion, or folding took place. write tilting, erosion, or folding next to the letter of any rock layer that was formed when the tilting, erosion, or folding took place. if you see no evidence of tilting, erosion, or folding, write none.

3. repeat steps 1 and 2 for record b. record the data in chart b.

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

i wish i could but this one is weird give me abc and i can solve it.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
