Explanation:
When fluorine gas reacts with calcium metal at high temperatures then it results into the formation of calcium fluoride.
Since, calcium has 2 extra electrons as its electronic distribution is 2, 8, 8, 2. Whereas each fluorine atom needs one electron to complete its octet.
Therefore, the chemical reaction equation will be as follows.
Hey there,
Based on my research and my understanding, your correct answer would be exactly 760 torr. Because if you do <span>Pt = P1 + P2 + P2, that will eventaully give your 760 torr.
