<h2><u>Answer:</u></h2>
The quantity of protons likewise decides the character of the component. Electrons have a negative charge. The furthest or valence electrons of a particle are the ones that partake in synthetic responses. A component's substance properties rely upon its valence electrons.
The general properties of issue, for example, shading, thickness, hardness, are instances of physical properties. Properties that portray how a substance changes into a totally extraordinary substance are called synthetic properties. Combustibility and consumption/oxidation obstruction are instances of compound properties.
Reactivity with other chemicals.
Toxicity.
Coordination number.
Flammability.
Enthalpy of formation.
Heat of combustion.
Oxidation states.
Chemical stability
Answer:
The concentration of the solution is 1.068×10⁻⁴M
Explanation:
Hello,
To find the concentration of the solution, we'll have to use Beer-Lambert law which states absorption is directly proportional to the concentration of the solution.
Beer-Lambert law = A = εCL
A = absorption = 2 - log₁₀%T = 2 - log₁₀(34)
A = 2 - 1.5314 = 0.47
A = 0.47
ε = molar absorption coefficient = 4400
C = concentration of the solution
L = path length = 1cm
A = εcl
C = A / εl
C = 0.47 / 4400 × 1
C = 1.068×10⁻⁴M
The concentration of the solution is 1.068×10⁻⁴M
The following is produced when propane (C₃H₈) is combusted completely : H₂O
<h3>Further explanation </h3>
Complete combustion of Hydrocarbons with Oxygen will be obtained by CO₂ and H₂O compounds.
If O₂ is insufficient there will be incomplete combustion produced by CO and H and O
Hydrocarbon combustion reactions (especially alkanes) 
For combustion of propane C₃H₈ (n = 3) ⇒ completely(excess O₂) :
C₃H₈+5O₂⇒3CO₂+4H₂O
The products of combustion : CO₂ and H₂O
