Nitrogen gas and hydrogen gas react to form ammoniagas. suppose you have of and of in a reactor. calculate the largest amount of that could be produced. round your answer to the nearest is 362.7 g of NH3
The balanced equation of the given reaction is represented as;
N2 (g) + 3H2 (g) -> 2NH3 (g)
From observation, we can see that the mole ratio between the elements in the reaction which are: N2, H2 and NH3 have a mole ratio 1 : 3 : 2
As we can see that N2 : H2 = 1:3
It means that the reaction will consume three times more moles of hydrogen than the moles of nitrogen consumed. Thus, the H2(hydrogen gas) will limit the amount of N2 (Nitrogen gas) that will take part in the reaction.
Thus,
No. of moles of N2 that will take part in the reaction is;
1 mole of H2 × 1 mole of N2/3 moles of H2
The moles of H2 will cancel out to give;
1/3 moles of N2
We are told we have 11.0 mol of N2.
Thus, remaining N2 will be; 11 - ⅓ = 32/3 moles of N2
The mole ration between N2 and NH3 as a earlier seen is 1:2.
Thus,
We have;
32/3 moles of N2 × 2 moles of NH3/1 mole of N2
The mole of N2 will cancel out to give;
64/3 moles of NH3
Now, atomic mass of NH3 = 17 g/mol
Thus, max amount of NH3 that could be produced is;
64/3 × 17 = 362.7 g

Nitrogen N2 gas and hydrogen H2 gas react to form ammonia NH3 gas. Suppose you have 11.0 mol of N2 and 1.0 mol of H2 in a reactor. Calculate the largest amount of NH3 that could be produced. Round your answer to the nearest 0.1 mol.
The conversion of an action potential (AP) generated by a motor neuron to contraction of skeletal muscle fiber is called excitation-contraction coupling. This activity will test your understanding of the sequence of events that occur during excitation-contraction coupling.
Place the events that occur during excitation-contraction coupling in the correct order from left to right.
Hints
AP propagates along sarcolemma
AP travels down T tubules to triads Voltage-sensitive proteins
open Ca2+ channels
Sarcoplasmic reticulum releases Ca2+
Ca2+ levels in sarcoplasm increase
Recall from the video that a single motor neuron can conduct action potentials to several skeletal muscle fibers within a muscle. Excitation-contraction coupling converts these action potentials in a muscle fiber to a contraction. As muscle fibers contract, the entire muscle shortens and pulls the tendons on either end of the muscle, producing muscle tension.
The events that occur during excitation-contraction coupling in the correct order from left to right are as: AP propagates along sarcolemma, AP travels down T tubules to triads, Voltage-sensitive proteins open Ca⁺² channels, Sarcoplasmic reticulum releases Ca⁺², Ca⁺² levels in sarcoplasm increase
The term "excitation-contraction" refers to the chain of events that connects the excitation of the sarcolemma. The sarcolemma is the membrane that connects the muscle cells, to the contraction of the muscles. Although the excitation-contraction coupling in the myocardium is, in many respects, comparable to that in skeletal muscle and smooth muscle.
The events that occur during excitation-contraction coupling in the correct order from left to right are as:

the genetic differences between bacteria and archaea translate into a variety of structural and functional adaptations. what feature is similar in both domains?
Both archaea and bacteria are prokaryotes, which means they lack membrane-bound organelles and a nucleus. Microbes are incredibly little, single-celled creatures that are invisible to the human eye.
Archaea and bacteria resemble each other in size and shape when we examine them under a microscope. As rods, cones, plates, and coils, they are present.
Using whatever energy and carbon sources are available, prokaryotes have been and can still survive in any environment. Prokaryotes have a variety of roles on Earth, including digesting dead species, flourishing inside living things like people, and participating in nutrient cycles like the nitrogen and carbon cycles. Both bacteria and archaea are prokaryotes, which include structures called flagella that function as propellers for the organisms as they move through their surroundings. In Eukarya, which also includes all other animals, plants, fungi, and single-celled protists, DNA is contained in nuclei that are separate from the rest of the cell. Both are single-celled microorganisms that lack nuclei. The fossil record shows that prokaryotes were the first living things.

The degree to which two chromosomes share repetitive elements determines the likelihood that this event will occur.
A DNA segment can be as small as a few bases or as large as a significant chromosomal region, but in terms of genomics, duplication refers to a type of mutation in which one or more copies are produced. All living things duplicate their DNA.
Therefore, A cell divides into two identical daughter cells after duplicating every component of it, including its chromosomes, during the mitotic process. The steps of mitosis are meticulously regulated by specific genes because this process is so crucial.

with only 7.3 million mi 2 of primary forests remaining worldwide, 23,000 mi 2 of these forests continue to be cut on an annual basis. discuss two major environmental concerns with this continual loss of primary forest land.
Forest deterioration and deforestation are the two major environmental concerns with this continual loss of primary forest land.
Why there is continuous forest loss?Forests are home to more than 75% of all land-based life. Forests are crucial to halting climate change because they act as a carbon sink, absorbing carbon dioxide that would otherwise be released into the atmosphere and cause a continuous change in weather patterns. The threats include forest deterioration and deforestation. Illegal logging is the main cause of forest degradation, while agriculture is the main cause of deforestation (although poorly planned infrastructure is also evolving into a substantial risk factor). Deforestation in tropical rain forests is particularly concerning because they are the natural habitat for much of the world's species. For instance, over the past 50 years, the Amazon has lost 17% of its forest due mostly to forest conversion for cattle grazing, highways etc.

when a trait is sex-linked recessive, how does that affect the likelihood of the phenotype being expressed in a hemizygous individual versus an individual who is homozygous or heterozygous
In case of sex-linked recessive trait, the hemizygous individual will always show the phenotype and the trait is more common in hemizygous individuals i.e. males. In case of heterozygous individuals which can be females they carry the allele as a carrier and do not express any phenotype. The homozygous recessive females will always display the phenotype.
Sex-linked recessive is the trait where the gene for any mutation or disease is present on the X-chromosomes. It can only be expressed when both the X-chromosome contain the defective allele. However males being hemizygous can express the phenotype.
Heterozygous is the condition where the trait is present in any one of the homologous chromosomes. Any trait during heterozygous state will be expressed in dominant condition but not in recessive condition.

genetic variation in a group of organisms enables some organisms to survive better than others in the environment in which they live. organisms of even a small population can differ strikingly in terms of how well suited they are for life in a certain environment. an example would be moths of the same species with different color wings. moths with wings similar to the color of tree bark are better able to camouflage themselves than moths of a different color. as a result, the tree-colored moths are more likely to survive, reproduce, and pass on their genes. this process is called natural selection, and it is the main force that drives evolution.
Genetic Diversity, Genetic variation is the existence of distinct gene sequences among various members of a species. Natural selection, one of the main factors guiding the evolution of life, is made possible by it.
Geographic variation refers to genetic variations among populations from various regions. Genetic drift or natural selection are to blame for this. The percentage of polymorphic gene loci or the proportion of heterozygous people at a given gene locus are two typical ways to quantify genetic diversity within a population.
Genetic diversity in populations is maintained by a number of factors. In populations of diploid organisms, potentially detrimental recessive alleles can be protected from selection by heterozygous individuals (recessive alleles are only expressed in the less common homozygous individuals).
