Answer:
Hydrothermal solutions
Explanation:
Vein deposits which cuts through rock layers are usually products of hydrothermal solutions.
Veins are rich ore deposits in which superheated water rich in dissolved minerals penetrated through a rock body and the minerals becomes precipitated and deposited in the process. Most veins have small width and a great length. Some occurs as veinlets depending on the nature of the weaknesses they trace out in a rock body.
Veins contains minerals such as gold, copper ore, rare earth metals. Most hydrothermal solutions contains minerals that are not compatible with the melt as rocks crystallize. They preferred to be carried with super heated water which deposits them seperately.
The mass of hematite that contains 8.0×10³ kg of iron is 2.29 × 10⁴ kg.
<h3>What are iron ores?</h3>
Iron ores refers to minerals in which iron occur in combined form found in the earth's crust.
Some ores of iron include:
- hematite,
- magnetite,
- limonite, and
- siderite.
Molar mass of hematite, Fe₂O₃ = 160 g/mol
Molar mass iron = 56 g/mol
Percent mass of iron in hematite = 56/160 = 35%
The mass of hematite that contains 8.0×10³ kg of iron = 8.0 × 10³kg/0.35 = 2.29 × 10⁴ kg.
Therefore, the mass of hematite that contains 8.0×10³ kg of iron is 2.29 × 10⁴ kg.
