sanitary pads and diapers contain higher phthalate contents than those in common commercial plastic products

The correct answer is because sanitary pads and diapers are in direct contact with external genitalia for an extended period of time, a significant amount of VOCs or phthalates may be absorbed into the reproductive system.

Sanitary pads and diapers are made of synthetic plastic materials that can leach into the environment when used. The amounts of volatile organic compounds (VOCs) (methylene chloride, toluene, and xylene) and phthalates (DBP, DEHP, DEP, and BBP) found in sanitary pads and diapers were measured in this study. VOC and phthalate concentrations in sanitary pads varied by 5,900 and 130 times, respectively. VOC and phthalate concentrations in diapers varied by three and sixty-three times between brands. The VOC concentrations in sanitary pads and diapers were comparable to those in residential air. However, sanitary pads and diapers had significantly higher phthalate concentrations than common commercial plastic products.

Hexane and octane are mixed to form a 45 mol% hexane solution at 25 deg C. The densities of hexane and octane are 0.655 g/cm3 an
avanturin [10]

Answer:

The required volume of hexane is 0.66245 Liters.

Explanation:

Volume of octane = v=1.0 L=1000 cm^3

Density of octane= d = 0.703 g/cm^3

Mass of octane ,m= d\times v=0.703 g/cm^3\times 1000 cm^3=703 g

Moles of octane =\frac{m}{114 g/mol}=\frac{703 g}{114 g/mol}=6.166 mol

Mole percentage of Hexane = 45%

Mole percentage of octane = 100% - 45% = 55%

55\%=\frac{6.166 mol}{\text{Total moles}}\times 100

Total moles = 11.212 mol

Moles of hexane :

45%=\frac{\text{moles of hexane }}{\text{Total moles}}\times 100

Moles of hexane = 5.0454 mol

Mass of 5.0454 moles of hexane,M = 5.0454 mol × 86 g/mol=433.9044 g

Density of the hexane,D = 0.655 g/cm^3

Volume of hexane = V

V=\frac{M}{D}=\frac{433.9044 g}{0.655 g/cm^3}=662.4494 cm^3\approx 0.66245 L

(1 cm^3= 0.001 L)

The required volume of hexane is 0.66245 Liters.

Which element would most likely have a positive electron affinity
STatiana [176]

Answer : Electron affinity (Eea) of an atom or molecule can be defined as the amount of energy released or spent when an electron is being added to a neutral atom or molecule in the gaseous state to form a negative ion.


Chlorine is considered to be the element which has highest electron affinity in the modern periodic table.


The general formula is X + e^{-} ----> X^{-} + energy


It is found that nonmetals have more positive Eea than metals.


Electron affinity increases across the group from left to right in the modern periodic table. Elements with small nucleus have high electron affinity.
