D

Question 12

Diamonds and graphite are both pure carbon.  they are both pure substances made of carbon atoms, but the atoms are arranged in different ways. Diamonds are one of the hardest substances on Earth. Graphite is very soft and will easily break apart.  What is the it about the structure of graphite that might explain its properties?

Accepted Answer

The layered structure of graphite allows the layers to slide past each other.

Answer

The layered structure of graphite causes the bonds between atoms to strengthen.

Answer

Graphite breaks apart easily because its atoms cause graphite to be dark in color

Question 13

Accepted Answer

water since it has 2 elements

Accepted Answer

table salt since it has 2 elements

Answer

tin since it is 1 element

Question 14

Beth has two unlabeled balloons, one filled with Hydrogen (H) gas and the second filled with Neon(Ne) gas. Beth also has several chambers filled with various gases and a poster showing the densities of these gases. She has no other materials or tools available to her to help her identify the element in each balloon.  Which gas from the poster should she use in an experiment to identify the element in each balloon?

Accepted Answer

He

Answer

Ar

Answer

O2

Question 15

Beth has two unlabeled balloons, one filled with Hydrogen (H) gas and the second filled with Neon(Ne) gas. Beth also has several chambers filled with various gases and a poster showing the densities of these gases. She has no other materials or tools available to her to help her identify the element in each balloon.  Explain why you chose that gas.

Accepted Answer

it's density is between the two mystery balloons, so one will sink and one will float

Answer

it's density is greater than the two mystery balloons, so both will float

Answer

it's density is less than the two mystery balloons, so both will sink
