Ammonium Iodide dissociates reversibly to ammonia and hydrogen iodide:

Chemistry
1 answer:
NeTakaya3 years ago
7 0

Answer:

The partial pressure of ammonia at equilibrium when a sufficient quantity of ammonium iodide is heated to 400°C Is 0.103 atm.

The correct option is A.

Explanation;

NH4I(s) ⇋ NH3(g) + HI(g)Kp = 0.215 at 400°C

NH4I(s)= 0.215

NH3(g)=0.103

HI(g)Kp=0.112

Therefore = 0.103 +0.112= 0.215

Therefore the partial pressure of ammonia at equilibrium is 0.103 atm

Archy [21]

Answer:

B) atom of Xenon

Explanation:

Xenon is already stable alone, because it has a complete octet, or 8 electrons. This graph is not an ion because it shows xenon is its default state, consisting of 8 electrons.

It is not a molecule because a molecule is a group of atoms, or a compound, what is shown is a singular atom.

Calculate the number of ATP generated from one saturated 10 ‑carbon fatty acid. Assume that each NADH molecule generates 2.5 ATP
larisa86 [58]

Answer:

Total ATP molecules produced = 66 molecules of ATP

Explanation:

A 10-carbon fatty acid when it has undergone complete oxidation will yield 5 acetyl-CoA molecules and 4 FADH₂ and 4 NADH molecules each. Each of the 5 acetyl-CoA molecules enters into the citric acid cycle and is completely oxidized to yield further ATP and  FADH₂ and NADH molecules.

The total yield of ATP in the various enzymatic step is calculated below:

Acyl-CoA dehydrodenase = 4 FADH₂

β-Hydroxyacyl-CoA dehydrogenase = 4 NADH

Isocitrate dehydrogenase = 5 NADH

α-Ketoglutarate dehydrogenase = 5 NADH

Succinyl-CoA synthase = 5 ATP (from substrate-level phosphorylation of GDP)

Succinate dehydrogenase = 5 FADH₂

Malate dehydrogenase = 5 NADH

Total ATP  from FADH₂ molecoles = 9 * 1.5 = 13.5

Total NADH molecules = 19 * 2.5 = 47.5

Total ATP molecules produced = 13.5 + 47.5 + 5

Total ATP molecules produced = 66 molecules of ATP

Salicylamide can undergo an iodination by electrophilic aromatic substitution. Arrange the procedural steps in order to iodinate
Tanzania [10]

The procedural steps in order to get iodinate salicylamide are as follows:

  • It begins first at a laboratory.
  • Secondly, one has to dissolve salicylamide in ethanol.
  • Then one has to add sodium iodide.
  • Later on, one has to add sodium hypochlorite to the ice cold solution of salicylamide and sodium iodide.
  • Thereafter one has to sodium thiosulfate.
  • It is better to Acidify by a person adding about 10% of  HCl.
  • The one has to collect the crude product through the use of vacuum filtration.
  • Lastly one then Recrystallize from hot ethanol.
<h3>What is Electrophilic aromatic substitution?</h3>

The Electrophilic aromatic substitution is known to be a kind of an organic reaction where an atom is said to be added or attached to a kind of aromatic structure (that is made up of hydrogen) is said to be replaced by an electrophile.

Several tomato plants are grown indoors next to a sunny window. The plants receive water and fertilizer and remain on the window
mrs_skeptik [129]

You can see my previous answer to this very same question on brainly.com/question/11374210.


The answer is:  option D. Response to environment.


Explanation:


As explained, plants (organisms in general) respond to the stimulus provided by the environment.


Such behavior is named tropism. Tropism may be positive or negative.


When the plant's stem bends toward the window, it is showing positive phototropism, which means that the plant growth response to light such that the stems bend toward light, permiting the leaves to receive more light.


I also mention that while the plant's stems posses positive phototropism they posses negative gravitropism and the roots posses positive gravitropism.


Gravitropism is the response of the plant growth to gravity.


Stems grow away from gravity meaning that this is negative gravitropism, but roots grow toward gravity which is positive gravitropism
