Limestone.

It is a sedimentary rock composed of calcite and aragonite. It is used as a building material mainly because it is easily available and easy to work with.

Limestone is used in the manufacture of steel as it is the primary raw material that helps to remove impurities from the iron ore and produces waste matter  that has low melting point and viscosity

A client with eczema has a prescription for a topical corticosteroid. the nurse cautions the client to use the product carefully
Eva8 [605]
The risk of systemic absorption is greater in the area of the face. Corticosteroids have anti-inflammatory and anti-proliferative effects and for that reason, they are administered in cases of eczema and dermatitis. However, their action has to be limited to the affected skin areas (the target organ) and not the systemic organs. The skin of the face is not as thick as on the rest of the body, so applying the corticosteroid cream on this area increases the risk of the absorption of the drug in the systemic circulation.

The two most abundant elements in the oceans are sodium and chlorine. Together they make a salt, halite. Sodium is dissolved in
antoniya [11.8K]

Answer:

Volcanic gases. (Ans A)

Explanation:

Ocean water is salty because of the presence of dissolved salt. When water contact with a rock it starts weathering processes and this process starts to dissolve the soluble elements such as sodium out of the rock.

In volcanic gases, lots of chlorine ions are present in the atmosphere, these ions easily dissolve with water and produce the large flux of chloride that splashes into the oceans. So, the most common source of chloride ions in ocean waters comes from the volcanic explosions.
