An aquarium holds 100 L of water (recall that 1 L of water has a mass of 1 kg). The base of the aquarium is 1 m by 0.5 m. What pressure is exerted on a table by the filled aquarium?

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

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.

5.6⋅10−^19  j
