Answer:
Covalent bond
Explanation:
A covalent bond is formed when two atoms share electrons. The shared electrons are positioned between the nuclei of the bonding atoms.
In the bonding between chlorine and hydrogen, chlorine has seven valence electrons. Hence, it needs one more electron in order for the atom to attain an octet structure. Hydrogen has one valence electron and needs one more electron in order to attain a duplet structure.
The two bonding atoms now share two electrons(provided by each of the bonding atoms) in a covalent bond such that chlorine has a complete octet and hydrogen has a complete duplet.
Answer:
C₃H₈
Solution:
Step 1: Calculating Moles for each Element:
C = Mass of CO₂ × (1 mol of CO₂÷ M.Mass of CO₂) × (1 mol of C ÷ 1 mol of CO₂)
C = 2.641 g × (1 mol of CO₂÷ 44.011 g.mol⁻¹) × (1 mol of C ÷ 1 mol of CO₂)
C = 0.0600 mol
H = Mass of H₂O × (1 mol of H₂O ÷ M.Mass of H₂O) × (2 mol of H ÷ 1 mol of H₂O)
H = 1.442 g × (1 mol of H₂O ÷ 18.106 g.mol⁻¹) × (2 mol of H ÷ 1 mol of H₂O)
H = 0.159 mol
Step 2: Calculate the Smallest whole number ratio as,
C H
0.0600 0.159
0.0600/0.0600 0.159/0.0600
1 2.654
Multiply ratio by 3,
3 7.96
Or,
3 ≈ 8
Result:
Empirical Formula of Propane is C₃H₈
