which of the following statements correctly describes the substance with the formula KI?
There are no statements.
Hahahahahaha, Dr Russ. That's so funny.
But it's true. :D
Let's spare Matt some embarrassment. Here are the answer options:
A. The compound of potassium iodide contains one ion of potassium and one ion of iodine.
B. There is a one-to-two ratio of potassium ions to iodide ions.
C. Potassium iodide is a molecular compound.
D. None of the above
It's NOT B, C or D. The answer is A in this test.
But, the answer could be B IF it were from another test. B WOULD be correct here if it were written like this:
There is a one-to-ONE ratio of potassium ions to iodide ions.
Not one-to-two. But one-to-one. That's why it's wrong in THIS test.
