Poll

Question image

Based on the atomic-scale models of the samples, which of the following claims do you think is best?

Claim 1: All three samples have the same properties. Therefore, they are the same substance.

Claim 2: Two samples have the same properties. Therefore, they are the same substance. However, one sample has a different set of properties. Therefore, this sample is a different substance.

Claim 3: All three samples have different properties. Therefore, they are different substances.

Poll

Does the evidence from the Sim support the claim that you chose?

=====

Claim 1: All three samples have the same properties. Therefore, they are the same substance.

Claim 2: Two samples have the same properties. Therefore, they are the same substance. However, one sample has a different set of properties. Therefore, this sample is a different substance.

Claim 3: All three samples have different properties. Therefore, they are different substances.

Yes

No
