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.
<u>Answer:</u> The number of moles of nitrogen gas is 0.505 moles.
<u>Explanation:</u>
To calculate the number of moles of nitrogen gas, we use ideal gas equation, which is:

where,
P = pressure of the gas = 4.27 atm
V = Volume of the gas = 2.96 L
T = Temperature of the gas = ![32.0^oC=[32.0+273]K=305K](https://tex.z-dn.net/?f=32.0%5EoC%3D%5B32.0%2B273%5DK%3D305K)
R = Gas constant = 
n = number of moles of gas = ?
Putting values in above equation, we get:

Hence, the number of moles of nitrogen gas is 0.505 moles.
Hey there!
Electrons are negatively charged and orbit the nucleus of the atom on energy levels (kind of in a cloud) :)

First, you have to know what reacts with Aluminum Nitrate so that you can balance the equation and find out the stoichiometric coefficient. I found a similar question from another website as shown in the picture attached. Balancing the reaction would result to:
2Al(NO₃)₃ + 3FeCl₂ --> 3Fe(NO₃)₂ + 2AlCl₃
<em>The coefficient is 2.</em>
