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.

For an enzymatically catalyzed reaction in which the measured values for KM and Vmax are, respectively, 10.0 mM and 0.172 mM min
abruzzese [7]

Answer:

17.2 minutes is the value of the turnover number.

Explanation:

Using Michaelis-Menten equation:

V = V_{max}\times \frac{[S]}{ (Km + [S])}

V_{max }=k_{cat}\times E_o

Where  :

V_{max} = max rate velocity

[S] = substrate concentration

K_m = Michaelis-Menten constant

V = reaction rate

k_{cat} = catalytic rate constant

E_o = initial enzyme concentration

We have :

K_m=10.0mM

E_o=10.0\mu M=10.0\times 0.001 mM

V_{max}=0.172 mM/min

V_{max} is the rate is obtained when all enzyme is bonded to the substrate. k_{cat} is termed as the turnover number.

k_{cat}=\frac{V_{max}}{E_o}=\frac{0.172 mM}{10.0\times 0.001 mM}

=17.2 minutes

17.2 minutes is the value of the turnover number.

For each of the following reactions, identify the missing reactant(s) or products(s) and then balance the resulting equation. No
Pachacha [2.7K]

Answer:

A. The reactants are= Li and O2

The balanced equation is:

4Li + O2 —> 2Li2O

B. The products are: MgCl2 and O2

The balanced equation is:

Mg(ClO3)2 —> MgCl2 + 3O2

C. The products are: Ca(NO3)2 and H2O

The balanced equation is:

2HNO3 + Ca(OH)2 —> Ca(NO3)2 +

2H2O

D. The products are: CO2 and H2O

The balanced equation is:

C5H12 + 8O2 —> 5CO2 + 6H2O

Explanation:

A. ____ —> Li2O

The reactants are Li and O2. Thus the equation is given below:

Li + O2 —> Li2O

Thus the equation is balanced as follow:

There are 2 atoms of O on the left side and 1 atom on the right side. It can be balance by putting 2 in front of Li2O as shown below:

Li + O2 —> 2Li2O

Now, we have 4 atoms of Li on the right side and 1 atom on the left. It can be balance by putting 4 in front of Li as shown below:

4Li + O2 —> 2Li2O

Now the equation is balanced

B. Mg(ClO3)2 —> __

The products are MgCl2 and O2

The equation is given below:

Mg(ClO3)2 —> MgCl2 + O2

The equation can be balance as follow:

There are 6 atoms of O on the left side and 2 atoms on the right side. It can be balance by putting 3 in front of O2 as shown below:

Mg(ClO3)2 —> MgCl2 + 3O2

Now the equation is balanced

C. HNO3 + Ca(OH)2 —>___

The products are: Ca(NO3)2 and H2O

The equation is given below:

HNO3 + Ca(OH)2 —> Ca(NO3)2 + H2O

The equation is balanced as follow:

There are 2 atoms of NO3 on the right side and 1 atom on the left. It can be balance by putting 2 in front of HNO3 as shown below:

2HNO3 + Ca(OH)2 —> Ca(NO3)2 + H2O

There are a total of 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of H2O as shown below:

2HNO3 + Ca(OH)2 —> Ca(NO3)2 + 2H2O

Now the equation is balanced

D. C5H12 + O2 —>__

The products are: CO2 and H2O

The equation is given below:

C5H12 + O2 —> CO2 + H2O

The equation can be balance as follow:

There are 5 atoms of C on the left side and 1 atom on the right side. It can be balance by putting 5 in front of CO2 as shown below:

C5H12 + O2 —> 5CO2 + H2O

There are 12 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 6 in front of H2O as shown below:

C5H12 + O2 —> 5CO2 + 6H2O

Now, there are a total of 16 atoms of O on the right side and 2 atoms on the left. It can be balance by putting 8 in front of O2 as shown below:

C5H12 + 8O2 —> 5CO2 + 6H2O

Now we can see that the equation is balanced.

What is produced by a neutralization reaction between an arrhenius acid and an arrhenius base?
stepladder [879]

Answer: Salt and Water

Explanation:

An Arrhenius acid (HCl) can best be defined as any substance that when added to water increases the concentration of H+ ions.

While an Arrhenius base (KOH) is any substance that when added to water increases the concentration of OH- ions.

When an Arrhenius acid such as HCl reacts with an Arrhenius base such as KOH, the end products will be salt and water, in a process called Neutralization Reaction.

HCl (aq) + KOH (aq)  -------> KCl (aq) + H2O (l)
