Answer:
4.13 moles of Fe will be produced in the reaction
Explanation:
To produce Fe from CO, we need to react Fe₂O₃ and the carbon monoxide.
The reaction is:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
1 mol of iron (III) oxide react to 3 moles of carbon monoxide in order to produce 2 moles of Iron and 3 moles of carbon dioxide.
We assume, the Fe₂O₃ in excess, so we propose this rule of three
3 moles of CO can produce 2 moles of Fe
Therefore 6.20 moles of CO will produce (6.20 . 2)/3 = 4.13 moles of Fe
The answer is; extremophiles
These organisms are found in places on earth that would be damaging to most life on earth. There are different categories of extremophiles depending on their environment. For example, those that live in the extreme cold (even below 150C ) are called Psychrophiles while Xerophiles live extreme desiccation.
Answer:
Crude oil is separated by fractional distillation. Crude oil is heated to vaporize the different hydrocarbons in a tank which is cool at the top and hot at the bottom. The vapours then rise and the different hydrocarbons condense at their specific boiling points, allowing them to be separated.
Lighter products, such as butane and other liquid petroleum gases (LPG), gasoline blending components, and naphtha, are recovered at the lowest temperatures. Mid-range products include jet fuel, kerosene, and distillates (such as home heating oil and diesel fuel).
Answer:
1. This reaction is <u>(A) Exothermic .</u>
2. When the temperature is decreased the equilibrium constant, K: <u>(A) Increases</u>
3.When the temperature is decreased the equilibrium concentration of Co2:<u> (A) Increases</u>
Explanation:
1. The pink color predominates at low temperatures, indicating that the commodity is preferred.
This is a reaction that is <u>exothermic.</u>
2. As the decrease in the temperature , the equilibrium constant , K ;
equilibrium constant = 
=![\frac{[CO^2^+][Cl^-^4]}{CoCl^2^-_4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BCO%5E2%5E%2B%5D%5BCl%5E-%5E4%5D%7D%7BCoCl%5E2%5E-_4%7D)
As the temperature drops, the concentration of
and 
rises, and K rises as well , thus it <u>increases </u>.
3. The equilibrium concentration of decreases as the temperature decreases:
When the temperature is lowered, the equilibrium shifts to the right , that is it <u>increases.</u>
