Which element is more difficult to take electrons away from tin or Gallium and why ?

Answers

In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). In fact, for the alkali metals (the elements in Group 1), the ease of giving up an electron varies as follows: Cs > Rb > K > Na > Li with Cs the most likely, and Li the least likely, to lose an electron.

Cesium (Cs) in particular can surrender its valence electron quite conveniently than lithium (Li). In fact, the ease with which the alkali metals give up an electron varies as follows: > Cs > Rb > K > Na Li is the most likely to lose an electron, followed by Cs and Li.

What is reactivity?

In chemistry, reactivity is the impulse that causes a chemical substance to undergo a chemical reaction, either on its own or in conjunction with other materials, resulting in the release of energy.

The reactivity of an element is a measure of how easily it will combine with other elements to form substances.

The number of electrons in an atom's outermost shell determines its reactivity. Noble gases have low reactivity so even though their electron shells are complete.

Cesium (Cs) in particular can more easily surrender its valence electron than lithium (Li).

In fact, the alkali metals' ability to give up an electron varies as follows: > Cs > Rb > K > Na Li has the highest probability of losing an electron, followed by Cs and Li.

Thus, these are some elements that is more difficult to take electrons away from tin or Gallium.

In the atmosphere, 50% of the air lies below an altitude of 89.0000655.

What do you mean by altitude of atmosphere?

Exosphere. Located between about 700 and 10,000 kilometers (440 and 6,200 miles) above Earth's surface, the exosphere is the highest layer of Earth's atmosphere and, at its top, merges with the solar wind.

The commonly accepted end of earth's atmosphere falls within the thermosphere at 62 miles (100 kilometers) above the earth's surface. This commonly accepted boundary is called the Kármán Line.

The Stratosphere extends around 31 miles (50 km) down to anywhere from 4 to 12 miles (6 to 20 km) above the Earth's surface. This layer holds 19 percent of the atmosphere's gases but very little water vapor.

Select all of the following that are a result of heating up a solution?
Molecules will move faster
Molecules will slow down
Molecular movement will not change
More collisions will occur between molecules

Answers

Answer:

a

Explanation:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

The results of heating up a solution are:

Molecules will move faster

More collisions will occur between molecules

According to the kinetic molecular theory, when a solution is heated up:

The temperature of the solution risesThe attractive forces binding the molecules weakensThe speed of the molecules increases. This means that the molecules  move faster than before The rate of collision between the molecules increases. This is because of an increase in the Kinetic Energy possessed by the molecules as the temperature rises

Therefore, among the given options, the results of heating up a solution are:

Explanation:

The organelle pictured (a chloroplast) seems to be absorbing energy from the sunlight and that is included in the process of photosynthesis.

The carbohydrates (glucose) are formed by the process of photosynthesis in the chloroplast of the cell which then sent to the mitochondria for the production of ATP through glycolysis. Thus, the correct option is F.

What is Photosynthesis?

Photosynthesis is the process of conversion of light energy (sunlight) into chemical energy (glucose). This process takes place in the chloroplast of plant cell where chlorophyll is present, this pigment (chlorophyll) is responsible for trapping the sunlight which is responsible for conduction of photosynthesis.

The products of photosynthesis (glucose) is sent to the mitochondria of cell for the production of ATP by the process of glycolysis. This ATP is then utilized by the cell in other cellular mechanisms.

What stage of respiration immediately follows the process depicted below? (2 points)

C) fermentation
D)krebs cycle

Answers

Image Attached

Answer:

D) Krebs' cycle

Explanation:

The stage of respiration shown is pyruvate oxidation. This is the intermediate stage between the first and second stages of aerobic respiration.

The first stage is glycolysis, which is the breakdown of glucose into two molecules of pyruvate. After pyruvate oxidation, the next stage is the Krebs cycle. The Krebs cycle is a series of reactions that release energy through  oxidation of acetyl-CoA.

During cell respiration, the reactants of glucose and oxygen are transformed into the products of carbon dioxide, water, and ATP. Which of the following cell transport processes would be relatively unaffected if a cell no longer had access to glucose? Choose 1 answer: Choose 1 answer: (Choice A) A The transport of calcium into a muscle cell via facilitated diffusion. (Choice B) B The transport of an amino acid into an intestinal cell from an area of low concentration to an area of high concentration gradient. (Choice C) C The transport of sodium against its concentration gradient in a brain cell. (Choice D) D The passive transport of a charged potassium ion (K^+ + start superscript, plus, end superscript) through a cell membrane.

Answers

The process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.

What is Cellular respiration?

Cellular respiration may be defined as the chemical process through which the breaking down of food occurs with the liberation of energy. This process takes place in the excess of oxygen and constructs energy from carbohydrates (sugars).

The excess glucose delivers the required energy for the cell to perform its metabolic activities. But when the amount of glucose is not significantly present in the cell, the process of transport of calcium into a muscle cell via facilitated diffusion remains unaffected.

This is because the transport of calcium occurs due to paracellular passive transport without the utilization of energy. While the rest of the process requires energy for the transport.

And due to a lack of glucose, cells do not have the ability to derive energy in form of ATP.

Therefore, the process of cell transport that would be relatively unaffected if a cell no longer had access to glucose is the transport of calcium into a muscle cell via facilitated diffusion. Thus, the correct option is A.

Suspended in the stroma of the chloroplast
Bound to free ribosomes
Based on the diagram, what is the site of modification and packaging of
proteins and lipids prior to export from the cell?

Answers

Answer:

1. Embedded in the plasma membrane

2. There is no diagram attached but the question can be answered based on general knowledge. The answer is Golgi apparatus/body.

Explanation:

1. Cholesterol is fat molecule produced in the Smooth Endoplasmic reticulum of animal cells. It is then transported to the plasma membrane, where it plays a vital role in the functionality of the plasma membrane. Hence, embedded in the plasma membrane of an animal cell is CHOLESTEROL, in addition to phospholipids.

2. The Golgi apparatus is an organelle in eukaryotic cells that functions in the modification and packaging of protein and lipid molecules produced by the RER and SER respectively.

The most likely location of cholesterol in an animal cell is A. Embedded in the plasma membrane.

Based on the diagram, the site of modification and packaging of proteins and lipids prior to export from the cell is the Golgi apparatus.

Cholesterol simply means a fat molecule that is formed in the smooth endoplasmic reticulum of animal cells.

It should be noted that the cholesterol is then sent It is then to the plasma membrane,

The Golgi apparatus is an organelle that can be found in eukaryotic cells. The function of the Golgi apparatus is the modification and the packaging of the lipid molecules and the protein molecules that are produced.
