Idk really but i hope you figure out the answer im not on that yet.
Answer:
17.2 moles of Iron are required
Explanation:
Based on the chemical reaction:
2Fe + 3S → Fe₂S₃
<em>2 moles of Fe react with 3 moles of S to produce 1 mole of Iron (III) sulfide</em>
<em />
Assuming and excess of sulfur, if we want to obtain 8.6 moles of Fe₂S₃ are required:
8.6 moles Fe₂S₃ * (2 moles Fe / 1mol Fe₂S₃) =
<h3>17.2 moles of Iron are required</h3>
An atom consist of mainly two parts, namely nucleus and electrons. In the nucleus, there are groups of protons and neutron DENSELY packed, each element has its own atomic number(number of protons) but can have different no. of neutron (isotop). within the proton and neutron, there are subatomic particles called quarks. Talking about the electrons, they move very quickly arround the nucleus and there are different energy level for electron to switch between. In chemical reaction, we are only concerning the no. of valence electrons.

The rate of change in the amount of silver supplied is equal to the ratio of the difference in the amount supplied to the number of years elapsed from 2005 to 2008. That is,
rate of change = (25 - 200) / (2008 - 2005) = -173/3
The answer is letter A.
Stir it,
Or as warmer water makes solutes dissolve faster Sarah can do that
