Answer:
An emulsifying agent is typically characterized by having <u><em>d. one polar end and one nonpolar end.</em></u>
Explanation:
Emulsifiers are substances that have the ability to bind, for example, fats with those substances that have mostly water in their conformation. In other words, the emulsifier facilitates mixtures of two or more immiscible liquid substances.
This is because the molecules of an emulsifier are often lipophilic (attract oil) at one end and hydrophilic (attract water) at the other. In other words it consists of a polar (hydrophilic) head group and a non-polar (hydrophobic) tail.
<u><em>An emulsifying agent is typically characterized by having d. one polar end and one nonpolar end.</em></u>
Answer:
pH = 12.544
Explanation:
0.0350M 0.0350M 0.0350M.........equilibrium
∴ pOH = - log [OH-]
∴ pH + pOH = 14
⇒ [OH-] = 0.0350 M
⇒ pOH = - Log (0.0350)
⇒ pOH = 1.456
⇒ pH = 14 - 1.456
⇒ pH = 12.544

Explanation: Balance the reaction of KOH + H3PO4 = K3PO4 + H2O using this chemical equation balancer!
Two [hydrogen] atoms and one [oxygen] atom
Answer:
The concentration of the solution, 
Explanation:
The absorbance of a solution can be calculated by Beer-Lambert's law as:
Where,
A is the absorbance of the solution
ɛ is the molar absorption coefficient (
)
C is the concentration (
)
l is the path length of the cell in which sample is taken (cm)
Given,
A = 0.20
ɛ = 27400 
l = 1 cm
Applying in the above formula for the calculation of concentration as:
So , concentration is:
