i hope this helped
They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid. Prokaryotic organisms have varying cell shapes.

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.
Answer:
Water absorbs 84cal.
Explanation:
The given information about water is:
- mass of water (m): 12g
- change in temperature (ΔT): 7°C
With the given information, and the specific heat of water (c=1cal/g.°C), we can calculate the aeat that water absorbs, using the heat formula:
So, water absorbs 84cal.
Answer:
9.47 mL
Explanation:
The reaction that takes place is:
- 2KOH + H₂SO₄ → K₂SO₄ + 2H₂O
First we <u>calculate how many KOH moles reacted</u>, using <em>the given concentration and volume of KOH solution</em>:
- 0.061 mol/L = 0.061 mmol/mL
- 0.061 mmol/mL * 26.7 mL = 1.6287 mmol KOH
Then we <u>convert KOH moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:
- 1.6287 mmol KOH *
= 0.8144 mmol H₂SO₄
Finally we <u>calculate the required volume of the H₂SO₄ solution</u>, using<em> the number of moles and given concentration</em>:
- 0.8144 mmol ÷ 0.086 mmol/mL = 9.47 mL
30-60 breaths per minute
A rabbit's heart rate should be 120-150 beats per minute. A rabbit's respiration rate should be 30-60 breaths per minute. A rabbit's temperature should be 101.3-104F.
