Scientists use models to help them represent things in nature that they cannot observe directly. They can also use models to make predictions. For example, scientists use Bohr models of atoms to predict chemical reactions between atoms, You can use models in the same way, but you must first understand what each model component represents. Which element is represented by this Bohr model? A. chlorine (Cl)
B. oxygen (O)
C. selenium (Se)
D. sulfur (S)

I think it’s chlorine (Cl)

Explanation:

I’m literally doing the same question right now

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
