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:
Atoms are neither created or destroyed.
Explanation:
The end result of a chemical change does not create or destroy any atoms. Matter cannot be created or destroyed, meaning the same amount of atoms exist before and after the change.
Answer:
Explanation:
Because the experiment has an different independent and dependent variable and each part has a different result of what type of copper or what type of control you are using for you experiment.

Answer:
The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.
Explanation:
Given data:
Wavelength of x-ray = 8.82 nm
frequency of x-ray = ?
Solution:
speed = Wavelength × frequency
frequency = speed / Wavelength
c = 3 × 10⁸ m/s
f = c/ λ
f = 3 × 10⁸ m/s /8.82 × 10⁻⁹m
f = 0.340 × 10¹⁷ s⁻¹
The wave with the wavelength of 8.82 nm have frequency of 0.340 × 10¹⁷ s⁻¹.
(3) Cl2(g) <==> Cl2(l), because it has an equilibrium between the two phases of liquid and gas.
