<span>Answer:
Moles HgO = 10.36 g/ 216.59 g/mol= 0.048
the ratio between HgO and O2 is 2 : 1
moles O2 formed = 0.048/ 2= 0.024
at STP one mole of any gas occupies 22.4 L
Volume O2 = 0.024 x 22.4 L/mol = 0.54 L</span>
C. All the known elements that exist in the world today
Answer:
because its not international language
Explanation:
because its not international language like English
There are 6 electrons in the atom of a carbon.
The first atomic level will be occupied by 2 electrons while the second will be occupied by 4 electrons.
Based on this, the outer valence shell of carbon (which is L shell) will be occupied by 4 electrons.
