Answer 1

What do you think the answer is, or your first and second option?

Answer 2

I think it is either A or B

Answer 3

I'm pretty sure it is A because, in part D it says the elements so the valance of electrons.

Answer 4

Ok so A.)

Answer 5

c: yes

Answer 6

Politely disagree with the previous response.

In chemical reactions, the atomic number remains the same. Think about a simple chemical reaction like 2H2 + O2 --> 2H2O. Notice how the hydrogen atoms and oxygen atoms still retain the same atomic number.

Now let's look at some simple nuclear reactions:

notice how, for nuclear reactions (except gamma decay), the atomic number changes. For example, in the alpha decay, Uranium changes its atomic number from 92 to 90, becoming Thorium

Answer 7

Ok so what do you think it is?

Answer 8

Please re-read what I have said - notice how chemical reactions don't have a change in atomic number, while nuclear reactions do.

Answer 9

Ik thats why i said it either has to be A or B

Answer 10

Notice how reaction D states that the number of atomic atoms remains the same, which is why it cannot be a nuclear reaction

Answer 11

Answer choices A and B state that it is a nuclear reaction, which means we can eliminate A and B

Between C and D which is a more accurate description of what a chemical reaction is?

Answer 12

D.

Answer 13

good, so choice D best represents reaction D

Answer 14

Yes
