Answer:
The answer to your question is 126.1°C
Explanation:
Boiling point Difference of boiling points
C₃H₈ - 42.1°C
C₄H₁₀ - 0.5°C 41.6 °C
C₅H₁₂ 36.1°C 36.6°C 41.6 - 36.6 = 5°C
C₆H₁₄ 68.7°C 32.6°C 36.6 - 32.6 =4°C
C₇H₁₆ 98.4°C 29.7°C 32.6 - 29.7 = 2.9°C
We can observe on the table that the difference of boiling points diminishes 1°C when the hydrocarbon has one more carbon, then the difference of temperature between the hydrocarbon of 8 carbons and the hydrocarbon of 7 carbons must be 2°C.
So, this difference is 29.7°C - 2°C = 27.7°C.
And the boiling point of octane is approximately 98.4 + 27.7°C = 126.1°C
Answer:
The two physical/ chemical processes by which carbon dioxide molecules in the air move to the cells of phytoplankton in the ocean are the photosynthesis and the biological carbon pump.
Explanation:
The biological carbon pump is the action of organisms to move carbon during chemical and biological interactions from the surface into the deeper ocean and then to rocks.
The biological carbon pump its composed of three processes, which are the photosynthesis, the gravity and the food web interactions. They are all part of the carbon cycle.
During the photosynthesis, the phytoplankton take up carbon dioxide from the atmosphere that is dissolved in the surface water, and receives the energy from the sun to turn it into glucose and oxygen.
In the cells of the phytoplankton, glucose is transformed into other organic compounds. This material has organic carbon that can end in two ways: it is incorporated to marine organisms during the food web interactions or it can be remineralised forming calcium carbonate in the ocean surface.
The remineralization can be done by many organisms to build its shells or skeletons, or by chemical processes that happen in the ocean. This process allows more carbon dioxide to enter the water and to continue the cycle.
So when marine organisms die, all its organic components sink into the bottom of the ocean and carbon-rich sediments are form. And after millions of years, these sediments turn into rocks after going through chemical and physical phenomenon.
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.
