How does the hydrogen concentration of a solution change when the pH shifts from 6 to 2? (4 points)

Answers

Answer:

the overall concentration of hydrogen ions is universely related to its PH and can be measured on the physical (figure 1). therefore, the more hydrogen ions present.

The hydrogen ion concentration of a solution increases when pH shifts from 6 to 2.

What is pH?

a metric for determining how basic or acidic a substance or solution is. The pH scale ranges from 0 to 14. A pH value of 7 is considered neutral on this scale, meaning it is neither acidic nor basic. It is more acidic if the pH value is below 7, and more basic if the pH value is above 7.

Typically, a pH meter is used to measure pH, which converts the difference in electromotive force (electrical potential or voltage) between suitable electrodes put in the solution under test into pH measurements.

The different solutions have different pH based on the concentration of hydrogen ions. The concentration of hydrogen ions increases when pH shifts from 6 to 2.

2) Earth

Explanation:

Here, the planet A is mars, and planet B is Earth as per the information given here.

What are planets?

A planet is basically a celestial body which orbits the Sun. It has enough mass to overcome rigid body forces as well as adopt a hydrostatic equilibrium shape (almost round), has cleared the area in and around its orbit, and is in orbit around the Sun.

A rocky planet is basically the feature of Mars. Volcanoes, impacts, winds, crustal movement, and chemical reactions have all changed its solid surface.

The surface of Earth, a rocky planet along with the mountains, canyons, plains, and other landforms, is solid and dynamic.

Basically, the world is mostly encapsulated with the component namely water.

The only planet in solar system renowned to have liquid water on its surface is Earth, which is the fifth largest planet overall.

Thus, A is mars and B is Earth.

Plastic wrap is commonly made out of PVC (Polyvinylidene Chloride). In recent years other PVC alternatives have become more popular. The most popular option in recent years is LDPE (Low-Density Polyethylene) because it is considered to be safer for the body. The best management for plastic wrap would have to be by you taking plastic wrap to local retail stores where they collect plastic grocery bags for recycling. Any package that you see with the How2Recycle Store Drop-Off label can be recycled this way.

Human waste from excretion is probably classified as organic waste, since it comes from you and the food you eat. The best management for human excretion would probably be sewer pipes that lead into the sewage system that lead into other mainframes.

Wastewater is an odd typing since it contains human waste, food scraps, oils, soaps and chemicals. The best management for this would include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.

Lactic acid fermentation can be modeled by which equation?
O Lactic acid + NADH → Pyruvic acid NADH
O Pyruvic acid + NAD+ → Lactic acid + NADH
O Lactic acid + NADH → Pyruvic acid + NAD+
O Pyruvic acid + NADH → Lactic acid + NAD+

Answers

Lactic acid fermentation can be modeled by the following equation: Pyruvic acid + NADHLactic acid + NAD+

LACTIC ACID FERMENTATION:

Fermentation is a process undergone by some anaerobic organisms. Ideally, the process of cellular respiration proceeds as follows in the presence of oxygen: Glycolysis- Kreb cycle - ETC.

However, in the absence of oxygen (anaerobic condition), the product of glycolysis which is pyruvic acid combines with an electron carrier (NADH) to give rise to lactic acid and NAD+.

This means that pyruvic acid is reduced while NADH is oxidized as modelled in the following equation:

Pyruvic acid + NADHLactic acid + NAD+

Learn more at: https://brainly.com/question/11502989?referrer=searchResults

Answer to Question 1:

Well, given the choices to the question above 'Lactic acid fermentation can be modeled by which equation?', I would say that the best choice would be 'Pyruvic acid + NADH → Lactic acid + NAD+', or in other words, Option D.

Explanation for Question 1:

For a further explanation expanding more on the first question and showing why, the user above's answer is super helpful.

Answer to Question 2:

For the additional question asked 'In the Krebs cycle, how is citric acid formed?', I didn't see the options, however I believe they are:

O Carbon dioxide bonds with a chain of coenzyme A.

O Pyruvic acid molecules are broken down by an acetyl group.

O Acetyl-CoA joins with a large molecule called ozaloacetic acid.

O Enzymes combine hydrogen ions, oxygen, and electrons.

^ This being said, I would say your best choice would be Option C.

Explanation for Question 2:

The Krebs cycle begins when acetyl-CoA combines with a four-carbon molecule called OAA, aka oxaloacetate. This begins to produce citric acid, in which has six carbon-atoms. This is why the Krebs cycle is also referred to as 'the citric acid cycle.'

answer ASAP

Answers

As to the model of the different types of saccharides displayed, we can name its efficiency as a clear strength, and its lack of more examples as a limitation.

Using models to display information can be advantageous in that they allow the user to visualize something that may otherwise be difficult to picture. This increases memory retention and increases learning.

One example of a strength displayed by this model is its efficiency. By this, I mean that the model provides a clear and easy way to compare the differences in structure between the types of saccharides by positioning them all onto the same page, near one another enough to make quick and easy comparisons.

The noticeable limitation of the model, however, is its lack of further examples. The model in question shows a single example for each type of saccharide, limiting the user's knowledge to the difference between the types only. After using this model, the user will still lack information as to how saccharides of the same type can vary from one another.
