This doesnt make sense, but you can put sodium in water and it will smoulder producing hydrogen gas.
It is false; sodium iodide is more soluble than sodium chloride in water.

Obsidian is created whenever water flows on top of still lava.

False. Dissolved oxygen in ocean water does not cause salinity. Salinity is primarily determined by the amount of dissolved salts in the water, such as sodium and chloride ions. Dissolved oxygen levels are influenced by factors like temperature, depth, and the presence of photosynthetic organisms.
When lemon juice (which is acidic) is mixed with sodium hydroxide (a strong base), a neutralization reaction occurs, resulting in the formation of water and sodium citrate - a salt. This reaction will produce heat and can be exothermic. It is important to handle sodium hydroxide carefully as it is a caustic substance.
Sodium doesn't dissolve in water, it reacts with water to form sodium hydroxide and hydrogen: sodium + water ----> sodium hydroxide + hydrogen
Sodium brings ions, organic molecules, vitamins and water into the epithelial cells, which is then pumped by Na/K ATPase into the interstitial space, which then flows into the blood.
The river water flows into the sea.
