Boyle's law state that the total pressure of an enclosed gas is inversely proportional to the volume of the container, as long as the temperature is constant
Nesterboy [21]3 years ago

Answer: Boyle's law

Explanation: It states that pressure of a gas is inversely proportional to the volume of a gas at constant temperature.

P∝\frac{1}{V}       at constant temperature

or If the pressure of gas is decreased, the volume increases if the temperature is unchanged and If the pressure of gas is increased, the volume decreases if the temperature is unchanged.

P_1V_1=P_2V_2

What structural feature of lecithin allows it to behave like an emulsifying agent?
stepladder [879]
Lecithin is an emulsifier agent that's composed of 5 smaller molecules: phosphoric acid, choline, glycerol( is the backbone), and two fatty acids. 

The fatty acids, which are hydrophobic (afraid of water), makes this substance more similiar to fats and represent the non-polar part of the lecithin.
The phosphate group is the polar portion of the molecule and it's the negatively charged. The choline is positively charged, which readily dissolve in water<span>.

</span><span>Lecithin is a good emulsifier because of these structural features. the hydrophobic contacts with the oil, while the hydrophilic end contacts with the water.</span>

Andreyy89
The answer is D. Evaporating water only breaks apart intermolecular bonds like H-bonds and dipole-dipole bonds, and does not change the chemical composition (or intramolecular bonds).

Irina-Kira [14]

<u>Answer:</u> The concentration of A after 865 seconds is 0.00125 M

<u>Explanation:</u>

The integrated rate law equation for second order reaction follows:

k=\frac{1}{t}\left (\frac{1}{[A]}-\frac{1}{[A]_o}\right)

where,

k = rate constant = 0.660M^{-1}s^{-1}

t = time taken = 865 second

[A] = concentration of substance after time 't' = ?

[A]_o = Initial concentration = 0.00440 M

Putting values in above equation, we get:

0.660=\frac{1}{865}\left (\frac{1}{[A]}-\frac{1}{(0.00440)}\right)

[A]=0.00125M

Hence, the concentration of A after 865 seconds is 0.00125 M
