Answer:
1. rocks are composed of grains of minerals which are formed by the longest natural chemical reaction
2. clear liquids are mainly sugar and water . they are transparent food and mainly are beverages , ice , grains etc stuff
3. concrete is made up of basically three components . water , aggregate ( rock , sand and gravel ) and portland cement .
4. salt consist of NaCl it is made up of sodium and chloride it is also called rock or halite salt
Explanation:
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.
Answer:
0.7atm
Explanation:
Given parameters:
Initial temperature = 25.2°C in Kelvin; 25.2 + 273 = 298.2K
Initial pressure = 0.6atm
Final temperature = 72.4°C in kelvin = 72.4 + 273 = 345.4K
Unknown:
Final pressure = ?
Solution:
Since we are dealing with pressure temperature relationships under a fixed volume, we use a simplification of the combined gas law to solve this problem.
At fixed volume;
where P and T are temperature values
1 and 2 are the initial and final states
Input the parameters and solve for P₂
P₂ = 0.7atm
