Answer: The saltiest locations in the ocean are the regions where evaporation is highest or in large bodies of water where there is no outlet into the ocean. The saltiest ocean water is in the Red Sea and in the Persian Gulf region (around 40‰) due to very high evaporation and little fresh water inflow.
Explanation: Sea water salinity is expressed as a ratio of salt (in grams) to liter of water. In sea water there is typically close to 35 grams of dissolved salts in each liter. It is written as 35‰ The normal range of ocean salinity ranges between 33-37 grams per liter (33‰ - 37‰).But as in weather, where there are areas of high and low pressure, there are areas of high and low salinity. Of the five ocean basins, the Atlantic Ocean is the saltiest. On average, there is a distinct decrease of salinity near the equator and at both poles, although for different reasons.Near the equator, the tropics receive the most rain on a consistent basis. As a result, the fresh water falling into the ocean helps decrease the salinity of the surface water in that region. As one move toward the poles, the region of rain decreases and with less rain and more sunshine, evaporation increases.Fresh water, in the form of water vapor, moves from the ocean to the atmosphere through evaporation causing the higher salinity. Toward the poles, fresh water from melting ice decreases the surface salinity once again. Water has a unique property. As the temperature decreases to 40°F (4°C) the molecules slow, water contracts and the density increases. Below 40°F (4°C) the molecules begin to bond to each other and as they do, the water begins to expand again, decreasing the density. At 32°F (0°C) all molecules are locked into a crystalline structure with a resulting nine percent expansion in size. This expansion, and corresponding decrease in density, is the reason ice floats. The amount of salt in sea water also determines the temperature at which sea water freezes. Adding salt to water lowers the freezing temperature. Water with a salinity of 17‰ freezes at about 30°F (-1°C) and 35‰ water freezes at about 28.5°F (-2°C). Yet, despite the saltiness of the ocean, sea ice contains very little salt, about a tenth of the amount of salt that sea water has. This is because ice will not incorporate sea salt into its crystal structure. Therefore, sea ice is actually drinkable. The temperature and salinity of the sea water also help determine its density. As the temperature of sea water decreases the density also increases. Also, as the salt content of sea water increases, so does its density. This makes the density of sea water, unlike fresh water, below the freezing point. So, in situations of sea ice formation, the salinity, and therefore the density of the underlying water continues to increase well after an area is iced over.
In the "Average Salinity" map (below), it shows the lowest salinity in the polar regions. Bear in mind, this image depicts surface salinity only. The surface salinity is lower in the polar regions than in the tropical regions due to melting each summer. However, each winter below the ocean surface, the increased salinity in the water due to ice formation, causes the water below the ice to sink and that sinking motion governs the motion of the ocean's deep-water currents.

Answers
Answer:
A. Empirical formula => C₂H₄O
B. Molecular formula => C₄H₈O₂
Explanation:
From the question given above, the following data were obtained:
Mass of C = 0.273 g
Mass of H = 0.046 g
Mass of O = 0.182 g
Molar mass of compound = 88 g/mol
A. Determination of the empirical formula of the compound.
C = 0.273 g
H = 0.046 g
O = 0.182 g
Divide by their molar mass
C = 0.273 /12 = 0.023
H = 0.046 /1 = 0.046
O = 0.182 /16 = 0.011
Divide by the smallest
C = 0.023 / 0.011 = 2
H = 0.046 / 0.011 = 4
O = 0.011 / 0.011 = 1
Thus, the empirical formula of the compound is C₂H₄O
B. Determination of the molecular formula of the compound.
Empirical formula = C₂H₄O
Molar mass of compound = 88 g/mol
Molecular formula =?
Molecular formula = [C₂H₄O]ₙ
[C₂H₄O]ₙ = 88
[(12×2) + (4×1) + 16]n = 88
[24 + 4 + 16]n = 88
44n = 88
Divide both side by 44
n = 88 / 44
n = 2
Molecular formula = [C₂H₄O]ₙ
Molecular formula = [C₂H₄O]₂
Molecular formula = C₄H₈O₂

will mark brainlest 1) Now that you have studied the facts about the Severn River, you are ready to make a decision. What questions would you want answered if you were to determine whether to build a tidal power plant at the Severn River?
Answers
Answer:
The questions I would like to answer are:
Will the productivity of the river severn offset the cost of installing the plant?
Is it possible to build a dam on site?
Is it possible to establish submerged turbines in this location?
How would human life and nature be impacted by the plant?
Explanation:
Tidal power plants are signals that use tidal energy to generate electricity. The installation of this type of plant is quite expensive and involves the establishment of dams on site to take advantage of the differences between high and low tides and the establishment of submerged turbines to take advantage of sea currents.
To decide whether I would decide to build a tidal plant on the Severn River, I would need to evaluate a few things to make sure that the project is viable. For that I would ask myself some questions like:
Will the productivity of the river severn offset the cost of installing the plant? (If the installation costs are greater than the capacity of this river to promote high generation of electricity, it would be better to abandon the project)
Is it possible to build a dam on site? Is it possible to establish submerged turbines in this location? (It is necessary to consider the physical and chemical characteristics of the place to know if it is possible to install these two equipment and in a way that they work efficiently)
How would human life and nature be impacted by the plant? (Projects like this include major environmental and social impacts. These impacts must be analyzed and ways to mitigate them must be considered and included in the project.)
