Answer:
Sodium arachidate; Sodium palmitate and Sodium palmitate
Explanation:
Triglycerides are esters of fatty acids with glycerol. In triglycerides, three fatty acid molecules are linked by ester bonds to each of the three carbon atoms in a glycerol molecule. The fatty acids may be same or different fatty acid molecules. Hydrolysis of triglycerides yields the three fatty acid molecules and glycerol.
Saponification is the process by which a base is used to catalyst the hydrolysis of the ester bonds in glycerides. The products of this base-catalyzed hydrolysis of triglycerides are the metallic salts of the three fatty acids and glycerol. The salts of the fatty acids are known as soaps.
For a triglyceride that has the fatty acid chains arachidic acid, palmitic acid and palmitic acid attached to the three backbone carbons glycerol, the saponification of the triglyceride with NaOH will yield the sodium salts or soaps of the three fatty acids as well as glycerol.
Arachidic acid will react with NaOH to yield sodium arachidate.
The two palmitic acid molecules will each react with NaOH to yield sodium palmitate.
Answer:
The equilibrium concentration of CH₃OH is 0.28 M
Explanation:
For the reaction: CO (g) + 2H₂(g) ↔ CH₃OH(g)
The equilibrium constant (Keq) is given for the following expresion:
Keq= 
=14.5
Where (CH3OH), (CO) and (H2) are the molar concentrations of each product or reactant.
We have:
(CH3OH)= ?
(CO)= 0.15 M
(H2)= 0.36 M
So, we only have to replace the concentrations in the equilibrium constant expression to obtain the missing concentration we need:
14.5= 
14.5 x (0.15 M) x 
= (CH₃OH)
0.2818 M = (CH₃OH)
Answer:
6.1 ×10^-19 J
Explanation:
From E= hc/λ
h= planks constant = 6.6×10^-34 Js
c= speed of light = 3×10^8 ms^1
λ= wavelength = 325 nm
E= 6.6 × 10^-34 × 3×10^8/325 × 10^-9
E= 0.061 × 10^ -17 J
E= 6.1 ×10^-19 J
The conversion factor for volume at STP is
or
. Since we want volume, we would use
. We conclude with the following calculations:
The answer is 9.744L H2
<h3>Answer:</h3>
The state of water is determined solely by the conditions of <u>pressure and temperature</u>.
<h3>Explanation:</h3>
Effect of Temperature:
Temperature has direct effect on the kinetic energy of water molecules. Greater the Temperature greater is the K.E of molecules and lesser is the intermolecular forces between molecules. Therefore, at temperature below 0 °C water exists in solid state, at temperature in between 0 and 100 °C it exists in liquid state and (at sea level) and above 100 °C it exists in vapor state.
Effect of Pressure:
The state of water is also influenced by the external pressure. For example, water can be converted into gas phase by reducing the external pressure (this technique is used in vacuum distillation where solvents are evaporated at temperatures lower than their boiling points) and also, the water can remain in liquid state even above 100 °C if the external pressure is increases (this method is being utilized in daily use pressure cookers).
