Answer:
72 electrons
Explanation:
The 6th shell could hold up to 2(6)² = 2(36) = 72 electrons
Lamarck was the first person to propose a fully formed theory of evolution.
When 25.6 g is burned, the moles of emitted into the atmosphere is 1.80 mol
<u>Explanation:</u>
The molar mass of octane is calculated as 8(12) +18(1) = 114 g/mol.
Where atomic mass of Carbon is C=12, and Hydrogen H=1.The sample contains 25.6 g of octane, Therefore
The combustion of octane can be written as:
The mole ratio can be represented as:
= 16:2 = 8:1.
Hence, the quantity of carbon dioxide emitted is:
= 1.80 mol
