Answer: Carbon Dioxide
Explanation: It is what it eeeeeeeez
Hg2O -> O2 + Hg
2Hg2O -> O2 + 2Hg
20g-> ?g + 18.6g
(1 molHg2O ) (1 mol O2) (32g O2)
20g 2Hg2O x ------------------- x ------------------- x -------------- = 0.77g O2
(834.36Hg2O) (1 mol Hg2O) (1 mol O2)
6 protons because it is the 6th letter and it only has 6 protons
Answer:
c.O
Explanation:
From the periodic table:
Ionization energy tends to increase from IE6 → IE7 drastically at 13329 to 71345. Hence, from this process, we can infer that the removal of electrons takes place from the inner shell which in turn has a higher affinity for the nucleus. This must be oxygen because oxygen contains 6 valence electrons. The removal of this valence electron after the sixth ionization results in the achievement of a stable nearest Noble gas configuration. Hence, the rapid change in the ionization is obvious from IE6 to IE7.
Thus, the element that relates to the IE trend is oxygen.
