The answer is c I know because I did did yesterday
The rate of a reaction can be increased by:
-using a catalyst- it lowers the activation energy and leads to less energy required to break bonds of reactants. This lower activation energy leads to more products formed with less time, hence an increase reaction rate.
-increasing temperature- the particles of a molecule move faster and undergo more collision which leads to an increase in the speed of the reaction.
-increasing pressure- means there is more particles of reactants in a reduced volume. The particles do not need to move long distances to find another particle to react with, hence the rate of reaction increases.
Using an inhibitor will not increase the rate of the reaction because, an inhibitor binds to the active site where a catalyst is supposed to act. This means a higher activation energy and thus a decrease in reaction rate.
Likewise, decreasing the concentration implies few particles available to collide with each other and that slow down the speed of the reaction.
Metals don't form covalent bonds because of the low ionization energes of the metal atoms. It is easier for them to release electrons rather than sharing it. But this is not always the case, there are some metals that can form covalent bonds.
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>
True
After the process of Ore processing, Enrichment, Fuel production and being passed through the reactor core the last remaining step is spent fuel disposal.
