How are density and salinity related?
Density and salinity are directly related in seawater - as salinity increases, the density of seawater also increases. This is because dissolved salts and other substances in seawater add mass without significantly changing the volume, thereby increasing the overall density. Conversely, a decrease in salinity will lead to a decrease in density.
How do volcanic eruptions add salt to seawater?
Volcanoes on the ocean floors, such as those found at the mid-oceanic ridges, give up ions to sea water. As the upwelling magma comes in contact with water, ions (and heat) are transferred from the magma to the water, which rises and forms white smokers and black smokers. Some of the ions precipitate out of solution and form minerals on the sea floor, while other ions remain in solution and make sea water taste "salty".
What happens when you add acid to magnesium?
When acid is added to magnesium, the acid reacts with the magnesium to produce magnesium chloride and hydrogen gas. The chemical reaction can be represented by the equation: 2HCl + Mg -> MgCl2 + H2.
How do volcanoes effect geography?
Volcanoes impact geography by creating new land through the deposition of cooled lava and volcanic ash. They also shape the land through the formation of mountains, valleys, and islands. The eruption of volcanoes can change the landscape by covering existing features with volcanic material or altering the course of rivers and drainage patterns.
Why add CaCO3 in isolation of casein?
Calcium carbonate is added to neutralize the excess of acetic acid which remain after the precipitation of casein.
What salts do volcanoes add to seawater?
For example chlorine from submarine volcanoes, to form sodium chloride.
What process does not add salt to seawater?
Precipitation, land water runoff and the melting of icebergs do not add salts to seawater.
Which process does not add salts to seawater?
Storms at sea. The evaporated water falls back into the ocean with no net effect on salinity.
Why Seawater is typically denser than freshwater?
Seawater is denser than freshwater because it contains dissolved salts and minerals, such as sodium and chloride, which add weight to the water molecules. These dissolved substances increase the overall mass of seawater and make it denser than freshwater.
How are density and salinity related?
Density and salinity are directly related in seawater - as salinity increases, the density of seawater also increases. This is because dissolved salts and other substances in seawater add mass without significantly changing the volume, thereby increasing the overall density. Conversely, a decrease in salinity will lead to a decrease in density.
How much sodium hydroxide in grams must be added to seawater to completely precipitate 86.9mg of magnesium?
To completely precipitate 86.9mg of magnesium from seawater, you would need to add an equal molar amount of sodium hydroxide. The molar mass of magnesium is about 24.3 g/mol, so 86.9mg is equivalent to about 3.57 mmol of magnesium. You would need the same amount of mmol of sodium hydroxide to completely precipitate the magnesium.
Can global warming cause volcanoes to erupt?
No, quite the opposite really. Volcanoes add to the atmospheric greenhouse gasses.
What are the 2 process that add salt to seawater?
The two processes that add salt to seawater are the chemical weathering of rocks on land, which release minerals into rivers that eventually flow into the ocean, and the evaporation of water from the ocean surface, leaving behind salt in the form of halite (table salt).
What happens when calcium chloride is added to a soap that lathered most?
When calcium chloride is added to a soap that lathered well, it can form insoluble calcium salts with the fatty acids in the soap. This can reduce the effectiveness of the soap by decreasing its ability to form lather and clean effectively.
What is the past tense of add?
The past tense of add is added.
What is the past tense of added?
"added" is the past tence for "add". there is no past tence for "added"
