Answer:
This ammonium laurel sulfates anion consists of a nonpolar hydrocarbon chain and a polar sulfate end group. It means it has a hydrophilic head and hydrophobic tail. There are ammonium ions, sulfate, and fatty acids present.
Lauryl sulfate has lauric acid attach to sulfate ions with carbon-sulfur bond, the fatty acid formed by the covalent bonds between C-C attached to hydrogens. Sulfur also bound to oxygen by covalent bonds. Nitrogen is surrounded by the four hydrogen atoms in the hydrophilic head.
Answer:
P = 0.75 atm
Explanation:
Using Boyle's law
Given ,
<u>For Bulb A</u>
Pressure = 190 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 190 / 760 atm = 0.25 atm
Volume = 200 mL
For Bulb B
Pressure = 1 atm
Volume = 400 mL
For Bulb C
Volume = 1.00 L = 1000 mL
Pressure = 75.994 kPa
The expression for the conversion of pressure in KiloPascal to pressure in atm is shown below:
P (kPa) = P (atm)
75.994 kPa = atm
Pressure = 0.75 atm
Also, Total volume, V = 200 + 400 + 1000 mL = 1600 mL
Using above equation as:
We get, Total pressure, P = 0.75 atm
Answer:
Specific heat capacity = 0.24 j/g.°C
Explanation:
Given data:
Mass of metal = 82.4 g
Heat absorbed = 846 j
Change in temperature = 67°C - 25°C
Specific heat capacity = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 67°C - 25°C
ΔT = 42°C
Q = m.c. ΔT
846 j = 82.4 g . c. 42°C
c = 846 j / 3460.8 g.°C
c = 0.24 j/g.°C
