Answer:
The largest anthropogenic source of CO in the United States is vehicle emissions.
Explanation:
One mole of a substance contains 6.02 × 10∧23 particles. Thus we first convert 89.2 g to moles. 1 mole of sodium contains 23 g
Hence 89.2 g = 89.2 / 23 g = 3.878 moles
Therefore, 3.878 × 6.02×10∧23 particles= 23.346 × 10∧23 particles
Hence 89.2 g of sodium contains 2.335 ×10∧24 particles
C. Formation of a new substance
Answer is: C alkane.
Name of this molecule is n-hexane.
Hexane is alkane (acyclic saturated hydrocarbon, carbon-carbon bonds are single) of six carbon atoms.
Carbon atoms in hexane have sp3 hybridization.
In sp3 hybridization hybridize one s-orbital and three p-orbitals of carbon atom.
Alkene has one double bond and alkyne has one triple bond.
