Answer:
24.2 mL.
Explanation:
<em>Assuming constant temperature</em>, we can solve this problem using <em>Boyle's law</em>, which states:
Where:
We <u>input the data</u>:
- 0.98 bar * 25 mL = 1.013 bar * V₂
And <u>solve for V₂</u>:
The closest option is the second one: 24.2 mL.
Answer:
C
Explanation:
Pressure it says it in the name its the force of colliding particles
Answer:
0.37 g
Explanation:
The molecular weight for Glycerol = 92
Number of Carbon atoms in glycerol (x)
= 3
Molecular weight of the Biomass ( Klebsiella aerogenes )
= 
= 
= 26.1
From the molecular weight of the Biomass, we can deduce the Degree of reduction for the substrate(glycerol denoted as
) as follows:
= (4×1)+(1×1.73)-(2×0.43)-(3×0.24)
= 4.15
Given that the yield of the Biomass = 0.40 g
However;
C = 
C = 
C = 1.41 g
Now , the oxygen requirement can be calculated as:
= 
= 
= 2.1 g/mol
Hence, we can say that the needed oxygen = 2.1 g/mol of the substrate consumed.
Now converting it to mass terms; we have:
= 
= 
= 0.3652 g
≅ 0.37 g
∴ The oxygen requirement for this culture in mass terms = 0.37 g
Answer:
Explanation
Hardness has been defined the level of difficulty with a smooth surface of a mineral may be scratched. The hardness of a mineral species is upon the strength of the bonds which compose its crystal structure Hardness is measured of how easily a material can be scratched or indented Hard materials are often very brittle.
