A sample of a gas in a 4 L container at 300 K has a pressure of 1 atm. If the temperature is increased to 600 K and the volume is decreased to 2 L, the pressure is likely to be closest to which of the following? 0.5 atm
в
1 atm
с
2 atm
D
4 atm

a polar bond is formed when electrons are shared unevenly between atoms

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.

c. orbital shape i hope this is correct
