Answer:

Two design criteria for the design of the ammonia making process are;

1) Sustainable hydrogen production by renewable energy

2) Sustainable use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water

Explanation:

Ammonia is produced from natural gas in the following process;

H₂ + RSH → RH + H₂S

H₂S + ZnO → ZnS + H₂O (Waste water)

CH₄ + H₂O → CO + 3H₂

CO + H₂O → CO₂ + H₂

Ammonia is then produced by reacting the produced hydrogen with nitrogen in the presence of a catalyst in a process known as the Haber-Bosch process as follows;

3H₂ + N₂ → 2NH₃

The

The design criteria for the design of the ammonia making process therefore as follows;

1) Sustainable use of renewable energy to produce hydrogen gas from the electrolysis of water

2) Use of the ammonia-water thermal absorption cycle to retrieve the ammonia present in the waster water.

Which one is one pkease?

matrenka [14]

$\qquad\qquad\huge\underline{{\sf Answer}}$

The Correct choice is D. Fe + S = FeS

because, in nature Iron (Fe) and Sulphur (S) are found in mono - Atomic form. so, There will be 1 Fe atom reacting with 1 S atom to form FeS (Iron sulphide)

Imagine you are working on ways to improve the process by which Iron ore containing Fe2O3 is converted into Iron: Fe2O3(s) + CO(

Goryan [66]

Answer:

1. theoretical yield of Fe = 105g.

2. Percentage yield of Fe = 83.71%

Explanation:

Step 1:

Data obtained from the question. This includes:

The equation for the reaction:

Fe2O3(s) + CO(g) -> Fe(s) + CO2(g)

Mass of Fe2O3 = 150g

Actual yield of Fe = 87.9g

Theoretical yield of Fe =?

Percentage yield of Fe =.?

Step 2:

Balancing the equation.

Fe2O3(s) + CO(g) -> Fe(s) + CO2(g)

The above equation can be balanced as follow:

There are 2 atoms of Fe on the left side and 1 atom on the right side. It can be balance by putting 2 in front of Fe as shown below:

Fe2O3(s) + CO(g) -> 2Fe(s) + CO2(g)

There are a total of 4 atoms of O on the left side and 2 atoms on the right side. It can be balance by putting 3 in front of CO and 3 in front of CO2 as shown below:

Fe2O3(s) + 3CO(g) -> 2Fe(s) + 3CO2(g)

Now the equation is balanced.

Step 3:

Determination of the mass of Fe2O3 that reacted and the mass of Fe produced from the balanced equation. This is illustrated below:

Fe2O3(s) + 3CO(g) -> 2Fe(s) + 3CO2(g)

Molar Mass of Fe2O3 = (56x2) + (16x3) = 112 + 48 = 160g/mol

Molar Mass of Fe = 56g/mol

Mass of Fe from the balanced equation = 2 x 56 = 112g

From the balanced equation,

160g of Fe2O3 reacted.

112g of Fe is produced.

Step 4:

Determination of the theoretical yield of Fe. This is illustrated below:

From the balanced equation,

160g of Fe2O3 produced 112g of Fe.

Therefore, 150g of Fe2O3 will produce = (150x112)/160 =105g of Fe.

Therefore, the theoretical yield of Fe is 105g.

Step 5:

Determination of the percentage yield of Fe. This is illustrated below:

Actual yield of Fe = 87.9g

Theoretical yield of Fe =105g

Percentage yield of Fe =.?

Percentage yield = Actual yield/Theoretical yield x100

Percentage yield = 87.9/105 x 100

Percentage yield = 83.71%
