Answer:
The correct answer is a) 48.16 grams of HCl will be produced, b) mass of chlorine consumed is 206 grams.
Explanation:
a) The reaction given is:
K₂S₂O₃ + 4Cl₂ + 5H₂O ⇒ 2KHSO₄ + 8HCl
Based on the given information, the mass of KHSO4 is 45 grams. The moles of KHSO4 can be determined by using the formula,
Moles = given mass/Molar mass
= 45/136.16
= 0.33 Moles of KHSO₄
From the reaction it can be seen that when 2 moles of KHSO₄ is produced, 8 moles of HCl is also produced. Therefore,
2 moles of KHSO₄ = 8 moles of HCl
So, moles of HCl will be,
Moles of HCl = 8 × 0.33/2
= 1.321 moles
Now the mass of HCl is,
Mass of HCl = Moles of HCl × Molar mass of HCl
= 1.321 × 36.46
= 48.16 grams of HCl
b) It is known that 1 mole is equal to 6.023 × 10²³ molecules
In the given case, the molecules of water is given, that is, 2.20 * 10²⁴ molecules. Now let us consider that the moles of water is x.
x mole of water = 2.20 × 10²⁴ /6.022 × 10²³
= 3.653 mole of H2O
From the reaction given, it can be seen that when 5 moles of water are consumed, 4 moles of chlorine are consumed.
5 moles of water = 4 moles of chlorine
3.653 moles H₂O = x moles of Cl₂
Moles of Cl₂ = 4 × 3.653 /5
= 2.906 moles Cl₂
Now the mass of Cl₂ determined as,
Mass of Cl₂ = moles of Cl₂ × Molar mass of Cl₂
= 2.906 × 70.9
= 206 grams

Which plate boundary and movement commonly create volcanoes that can result in the development of habitable islands? Explain how islands can be created by plate tectonics. Plz hurry up I need this done in five min
The plate boundary and movement that commonly create volcanoes that can result in the development of the habitable island are convergent plates.
What are volcanoes?Volcanoes are the eruption of lava or magma from the earth's crust. This happens due to earthquakes. Due to the earthquake, the plate's tectonic collide with each other.
When the tectonic plates collide with each other three types of formation happen, both plates move upwards both played move away from each other or one plate goes under the other plate.
As volcanoes erupt, layers of lava are built up that could someday break the surface of the water. An island is created when the tops of the volcanoes rise above the surface of the ocean.
Thus, convergent plates are those that frequently result in volcanoes and plate boundary movement that can lead to the establishment of a habitable island.

What will be the approximate temperature of the liver if a victim dies at 3:15 pm and is found at 4:15 pm on the same day? (Assume ambient temperatures are normal)
98.6
97.2
95.8
99.5
Answer:
c
Explanation:
I think its c. sorry if im wrong
The approximate temperature of the liver if a victim dies at 3:15 pm and is found at 4:15 pm on the same day is 95.8. So, the correct option is C.
What do you mean by Ambient temperature?Ambient temperature may be defined as the air temperature of any object or environment where equipment is stored.
After the death of a victim, the temperature of the liver is found lower than that of the normal temperature of the body. Because as the individual dies, the speed of blood movement decreases with respect to time.
Therefore, The approximate temperature of the liver if a victim dies at 3:15 pm and is found at 4:15 pm on the same day is 95.8.

After a polypeptide chain is synthesized, it may undergo additional processing to form the finished protein. Learn how their functions are based on their three-dimensional structures, which ... bonds are formed by a biochemical reaction that extracts a water molecule as it joins to protein structure because these side chains can bond with one another to these stable folding patterns make up the secondary structure of a protein. A genotype is an organism’s set of heritable genes that can be passed down from parents to offspring. The genes take part in determining the characteristics that are observable in an organism, such as hair color, height, etc. An example of a characteristic determined by a genotype is the petal color in a pea plant. Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.
Once a protein is made, its biochemical and structural properties play a role in producing option a. phenotype.
Phenotype is the observational traits or characteristics of an individual organism. This is an aspect that includes the morphology and the physical form of an organism.
Phenotypes are produced as genetic material that is Chromosomes and DNA are produce proteins, and once the protein is prepared, then proteins, contribute to the structural properties of the cell to make physical form or phenotype.
The biochemical and structural properties plays role in producing the phenotype as the various enzyme and biological reactions help in maintaining physical form and morphology and other aspects.

circulatory system summary
Answer:
The circulatory system or vascular system is an organ system that helps in the transport of the blood from and to the heart. The blood transport also takes oxygen, nutrients, hormones, and other components from the heart to the various part of the brain with the help of the arteries and carry waste such as carbon dioxide to the heart in veins.
The oxygenated blood enters in the left atrium and moves to the left ventricle to the aorta and starts its journey to the body whereas deoxygenated blood enters in the right upper chamber or right atrium of the heart and pump to the right lower chamber and to the lungs to carry the oxygen again. This process is a continuous process.

Answer:
How can we explain why there is so much diversity of life on Earth today?
There are several key reasons for high biodiversity in tropical ecosystems. High NPP directly contributes to α-diversity by supporting more species with minimum viable populations, whereas enlarged populations of each organism increase overall mutation frequency and hence intraspecific genetic variation.

Sex Linked Inheritance
Why are women often carriers of X-linked traits but rarely affected by them?
Answer:
See the answer below
Explanation:
Women are often carriers of X-linked traits but are rarely affected by the trait because they have two X chromosomes and the two have to carry the X-linked allele in order for them to be phenotypically affected, especially if the trait is a recessive one.
Unlike men that are XY and only require one X-linked allele in order to be affected for X-linked recessive traits, women need two alleles - one on each chromosome - in order to be affected. One of the X chromosomes of a woman usually comes from the woman's father and the other one from her mother. In order to be affected, a woman must inherit an affected chromosome from her father and her mother respectively, thereby reducing the probability of having the trait.
The X chromosome of a man usually comes from his mother. Hence, a man only needs to inherit an affected chromosome from his carrier mother to be affected for the trait, thereby increasing the probability of having the trait when compared to a woman.
This is not the case for X-linked dominant traits where both men and women have an equal chance of being affected.
Women carry two XX chromosomes in their cells. They carry the X chromosome but rarely gets affected by the trait because to be phenotypically affected they should carry X linked disease trait on both the X chromosomes.
Especially in the case when the trait is recessive then they should have two XX chromosomes which are linked to traits.
In the male, they have one X and one Y chromosome so they acquire an X chromosome and gets affected by it.
In male presence of one X chromosome from the carrier mother is enough to pass the trait. While in females to have X linked recessive trait they should have two alleles.
The woman does not get affected as one chromosome comes from the father and the other from the mother so to be affected the woman must acquire genes with traits from both parents.
Therefore, women are often carriers but are rarely affected by them.
