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.
These events are actually sorted right, according to the time they occurred.
1. Democritus proposes the existence of atoms - this happened in the 5th century BC
2. Dalton's atomic theory - it was first presented in 1803
3. J.J. Thomson discovers the electron - happened in 1897
4. Rutherford's gold foil experiment - somewhere between 1908 and 1913
5. Bohr model - it was introduced in 1913
6. Schrodinger's wave - the equation was published in 1925
The ideal gas equation is;
PV = nRT; therefore making P the subject we get;
P = nRT/V
The total number of moles is 0.125 + 0.125 = 0.250 moles
Temperature in kelvin = 273.15 + 18 = 291.15 K
PV = nRT
P = (0.250 × 0.0821 )× 291.15 K ÷ (7.50 L) = 0.796 atm
Thus, the pressure in the container will be 0.796 atm
Answer:
It's explained below.
Explanation:
An everyday situation is when we raise an object.
Now, when we raise an object, energy is transferred to the Earth object system and thus the gravitational field energy of the system will increase.
Now, this energy is usually released when the object falls. The mechanism of this release is known as gravitational force.
In the same manner, two magnetic and electrically charged objects that are interacting at a distance will exert forces on each other and this can lead to transfer of energy between the interacting objects.
We can first find the number of moles using the ideal gas law equation,
PV = nrT
where P - pressure - 1000 mmHg / 760 mmHg/atm = 1.32 atm
V - volume - 100 x 10⁻³ L
n - number of moles
r - universal gas constant - 0.08206 LatmK⁻¹mol⁻¹
T - temperature in Kelvin - 95 °C + 273 = 368 K
substituting these values
1.32 atm x 100 x 10⁻³ L = n x 0.08206 LatmK⁻¹mol⁻¹ x 368 K
n = 0.00437 mol
molar mass can be determined as follows
molar mass = mass present / number of moles
molar mass = 0.597 g / 0.00437 mol = 136.6 g/mol
molar mass of gas is 137 g/mol
