When ionic compounds are added to water, they dissociate or break apart into ions. In the case of table salt, salt added to wate

r dissociates into sodium ions and chloride ions. This would seem to be a chemical change. However, scientists do not consider this to be one, because the solid table salt remains after the water is evaporated. The atoms recombine into their original arrangement once the water is removed.
Which word from the selection helps you understand that physical changes can be undone?
a added
b dissociate
c recombine.
d removed​

How many moles of coF3 are produced when 1.25 moles of 3co reacts
oee [108]

Answer:

1.25 moles

Explanation:

First, we need to balance the equation. Essentially, this means making sure we have the same number of each atom on each side.

On the left side, we currently have:

- 1 Co atom

- 2 F aomts

On the right side, we have:

- 1 Co atom

- 3 F atoms

To balance it, add a 2 to Co on the left, 3 to F2 on the left, and 2 to CoF3 on the right:

2Co+3F_2 → 2CoF_3

Now, we have 1.25 moles of Co, and since the ratio between Co and CoF3 is 1:1, we also have 1.25 moles of CoF3.

Thus, the answer is 1.25 moles.
