A gas has a pressure of 710 kPa at 227C. What will its pressure be at 27C, if the volume does not change?

so what is the problem with your lab report and whats the subject of the lab report? i will you

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.

i belive it is water

answer carbon and three oxygen atoms;
