Answer:
a) The approximate absorbance of benzoic acid at 228 nm? : A = 0.8
b) The molar absorptivity(∈)
of benzoic acid at 228 nm? : ∈ = 
Explanation:
Looking at the absorbance spectra, we can see that the approximate absorbance of benzoic acid at 228 is 0.8.
mass concentration of benzoic acid = 
the molar concentration of benzoic acid = (mass concentration of benzoic acid) / (molar mass of benzoic acid )
molar concentration of benzoic acid = 
molar concentration of benzoic acid = 
molar absorptivity (∈) of benzoic acid = (absorbance) /[ (molar concentration of benzoic acid ) × (path length) ]
∈ = (0.8) / [ (
) ×(1.00 cm)]
= 
Answer:
either bacterial cells or plant cells but I think bacterial
Explanation:
from google: Bacteria are single celled microbes. Bacteria are classified into five groups according to their basic shapes: spherical (cocci), rod (bacilli), spiral (spirilla), comma (vibrios) or corkscrew (spirochaetes). ... They can exist as single cells, in pairs, chains or clusters.
- cannot be human or mouse cells as both are animals and animal cells do not have cell walls
They dont have definite shape, high density and volume.
But they can be mixed together very easily
hope you got your answer
Answer:
Explanation:
The reaction can be represented by this nuclear equation: 23892U → 23490Th + 42He + Energy.
