Sulphur is located in the third period and group 16. The general electronic configuration of group 16 is therefore the maximum number of valency electrons in group 16 is 6. The electronic configuration of sulphur is [Ne]
. Sulphur has six valency electrons whereas sulphur can have more than eight electrons in its valency shell as it have an empty d-shell electrons can accumulate in the empty d-shell. The complete d-shell and the
orbital will be empty. As each orbital can accept 2 electrons, sulphur can have 12 valency electrons in its valency shell.
In the equation:
1 answer:
Answer:
B) 16 g
Explanation:
- 2H₂ + O₂ → 2H₂O
First we <u>convert 4 moles of O₂ into moles of H₂</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:
- 4 mol O₂ *
= 8 mol H₂
Finally we <u>convert 8 moles of H₂ into grams</u>, using <em>its molar mass</em>:
- 8 mol H₂ * 2 g/mol = 16 g
Thus, the correct answer is option B).
