Yo sup??
The answer to your question is option c ie
c.9
the rest 12 are under non essential as they are produced by our body itself
Hope this helps.
Answer: K = 284
Explanation:
Gibbs free energy (DG) = RT(InK)
Where :
R = Gas constant = 8.314J/K/mol = 0.008314KJmol/K
T = temperature in Kelvin = 298K
K = dissociation rate
DG = 14
DG = RT(InK)
14 = 0.008314 × 298 × (InK)
14 = 2.477572 × InK
Ink = (14 ÷ 2.477542)
InK = 5.6507619
K = 284
Answer:
Physicol properties can be extensive or intensive. Extensive properties vary with the amount of the substance and include mass, weight, and volume
Explanation:
The mechanical property of steel that characterizes its resistance to permanent deformation is ductility.
Am alloy is a substance prepared by adding one or more elements to a base or parent metal to obtain desirable properties.
Steel is an alloy of Iron and carbon in the composition of 99.8% and 0.2% respectively.
The mechanical or physical properties of steel include:
- It is more malleable and ductile than iron.
- It is harder and stronger.
- it can withstand great stress and strain.
The ductility of a metal like steel is the ability of a metal to change its shape without breaking, that is, resistance to permanent deformation.
Therefore, the mechanical property of steel that characterizes its resistance to permanent deformation is ductility.
