A sample of 25L of NH³ gas at 10°C is heated at constant temperature until it fills a volume off 50L. What is the new temperature in C? BACK

if you mean hydrogen and oxygen then water is the product

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.
