Answer:
FAS concentration = 1.61*10^-4M
Explanation:
Beer Lambert's law relates the absorbance (A) of a substance to its concentration (c) as:
where ε = molar absorption coefficient
l = path length
A plot of 'A' vs 'c' gives a straight line with slope = εl
In addition absorbance (A) is related to % Transmittance (%T) as:
A = 2-log%T----(2)
For the FAS solution, the corresponding calibration fit is given as:
y = 3678(x) + 0.056
This implies that the slope = εl = 3678
It is given that %T = 25.6%
Based on equation(1):

Balanced chemical reaction: C₃H₈(g) + 5O₂(g) → 3CO₂(g) + 4H₂O(g).
<span>There are same number
of atoms of on both side of balanced chemical reaction: ten oxygen atoms, three carbon atoms and eight hydrogen atoms.
</span>Carbon is oxidized and oxygen is reduced in this balanced chemical reaction of combustion of propane.
Answer:
I, II
Explanation:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
