An object floats in the beaker ad shown. when it was put into the beaker, it displaced an amount of water into the graduated cylinder at the left. given that the liquid in the beaker is water (density= 1g/ml), what is the mass of the object?

a) 1 g
b) 5 g
c) 10 g
d) 31.4 g

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

what are the statements

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.
