if electrons are received from only glycolysis, how many molecules of oxygen can be reduced by one glucose molecule?

Answers

Answer 1

Hence one molecule of oxygen can be reduced  by one glucose molecule, if electrons are received from only glycolysis

The balanced chemical equation for the conversion of glucose to pyruvate shows that four hydrogen atoms (four protons and four electrons) are also formed:

CH 206 — 2 CH3-C-C-OH + 4H+ + 4e Glucose Pyruvate

Since there could be  4 lectrons and 4 hydrogens  from one molecule of that are from glucose to pyruvate step.

O2 + 4H+  + 4e-  = 2H2O

Hence one molecule of oxygen can be reduced .The method by which glucose is metabolised to create energy is known as glycolysis. It generates water, ATP, NADH, and two pyruvate molecules. It doesn't need oxygen to happen since it happens in a cell's cytoplasm. In both aerobic and anaerobic species, it happens.

What is the relationship among the efficieny output work and input work of a machine?

Answers

The efficiency of a machine is the ratio of the output work it performs to the input work required to operate it. This ratio is expressed as a percentage, and it tells you how much of the input work is converted into useful output work.

For example, if a machine requires 10 units of input work to perform 5 units of output work, its efficiency would be 50%. This means that 50% of the input work is converted into useful output work, while the remaining 50% is lost as waste heat, friction, or other forms of energy dissipation.

In general, the efficiency of a machine is determined by its design, as well as the materials and components used to construct it. Machines that are well-designed and constructed with high-quality materials will typically have higher efficiencies than those that are poorly designed or made with lower-quality materials.

It's also important to note that the efficiency of a machine can vary depending on the type and amount of work it is performing. For example, a machine may be more efficient at performing certain tasks than others, or it may become less efficient as it wears out or is subjected to heavy use.

9. Why did your water appear to boil at a temperature less than 100°C? Use the definition of temperature to
help with your answer.

Answers

The boiling requires overcoming air pressure with vapor pressure, the boiling temperature of water depends on your height from sea level. Additionally, although this tends to raise the boiling point, it relies on the presence of contaminants in the water.

However, water boils at sea level at a temperature of 100 degrees Celsius. It serves as a definition. Because that is what the Celsius system is founded on, that temperature was picked. Actually, the temperature that pure liquid water at sea level cannot get above is 100 degrees Celsius, which is the most that it can be heated to before plateauing. The "boiling point" measures the actual object in question.

If you gauge the temperature from the first sign of boiling, it may occur at a little lower levels. Whisps of vapor may be seen around 90–95 degrees, but if you are at sea level with a reliable thermometer and clear water, the temperature should increase to 100 and remain there until the water starts to boil.

What is the percent compositions for nature's mix of lithium isotopes? What do you notice about the average atomic mass compare to the mass numbers for these same lithium isotopes? How does this relate back to how the average atomic mass is calculated?

Answers

The percent compositions for the naturally occurring isotopes of lithium are as follows: lithium-6 (7.5%), lithium-7 (92.5%), and lithium-8 (0.01%). The average atomic mass of lithium is calculated by taking into account the masses of all of its naturally occurring isotopes and the percent abundance of each isotope. When we look at the average atomic mass of lithium and compare it to the mass numbers of its isotopes, we can see that the average atomic mass is not equal to any of the individual isotope mass numbers. This is because the average atomic mass is a weighted average that takes into account the percent abundance of each isotope. Therefore, the average atomic mass of lithium is not the same as the mass number of any of its individual isotopes.

Answers

If you have 25 ml of a buffer solution at an initial ph, and it takes 13 ml of 0.1m hcl to change the buffer to ph -1, 130 ml/M is the buffer capacity for this solution.

The buffer capacity of a solution is a measure of its ability to resist changes in pH when small amounts of acid or base are added. It is defined as the amount of acid or base that must be added to the solution to change its pH by one unit.

To find the buffer capacity of a solution, we need to know the initial pH of the solution and the amount of acid or base required to change its pH by one unit.

In this case, we are given that the initial pH of the buffer solution is some value, and it takes 13 mL of 0.1 M HCl to change the pH by 1 unit. We can use this information to calculate the buffer capacity as follows:

Buffer capacity = amount of acid or base required to change pH by 1 unit / concentration of acid or base

The molecule O=C=S) is linear and has a Lewis structure analogous to that of CO2. Would you expect this molecule to be nonpolar?

Answers

The molecule O=C=S is linear and has a Lewis structure analogous to that of CO2. This molecule is polar molecule.

What are polar molecules?

Polar molecules are molecules that have two oppositely charged ends. Polar molecules exist as a result of differences in the electronegativities of the atoms of the elements found in the molecule.

With two electron domains around the central atom .the electron domain & molecular geometries are linear .sinces oxygen is more electronegative than sulphur.

The bond dipole symmetrically distributed around the carbon atom , are not identical and therefore,the bond dipole do not sum to zero.

Therefore, OCS molecule is a polar molecule not a non polar.

Answer: Pour résoudre ce problème, nous devons trouver le rapport molaire de l'aluminium à l'oxyde d'aluminium. Pour ce faire, nous devons d'abord trouver le nombre de moles d'aluminium et d'oxyde d'aluminium. Nous pouvons le faire en utilisant la loi des nombres d'Avogadro, qui est la relation entre le nombre d'atomes et le nombre de moles.

Pour trouver le nombre de moles d'aluminium, nous devons d'abord trouver le nombre d'atomes d'aluminium. Nous le faisons en multipliant le nombre d'atomes d'aluminium par l'équation chimique donnée. 3al * 1 = 3 atomes d'aluminium.

Nous pouvons maintenant trouver le nombre de moles d'aluminium en divisant le nombre d'atomes d'aluminium par le nombre d'Avogadro (6,02 x 10^23). 3atomes d'aluminium/6,02x10^23= 5,00 x 10^-23 moles d'aluminium.

Nous devons maintenant trouver le nombre de moles d'oxyde d'aluminium. Pour ce faire, nous devons trouver le nombre d'atomes d'oxygène et le multiplier par 2 pour obtenir le nombre d'atomes d'oxyde d'aluminium. Nous pouvons le faire en multipliant le nombre d'atomes de perchlorate d'ammonium par l'équation chimique donnée. 3NH4ClO4 * 4 = 12 atomes d'oxygène

Nous pouvons maintenant trouver le nombre de moles d'oxyde d'aluminium en divisant le nombre d'atomes d'oxygène par le nombre d'Avogadro (6,02 x 10^23). 12atomes d'oxygène/6,02x10^23= 2,00 x 10^-22 moles d'oxyde d'aluminium.

Maintenant que nous avons trouvé le nombre de moles d'aluminium et d'oxyde d'aluminium, nous pouvons trouver le rapport molaire de l'aluminium à l'oxyde d'aluminium. Nous le faisons en divisant le nombre de moles d'aluminium par le nombre de moles d'oxyde d'aluminium. 5,00 x 10^-23/2,00 x 10^-22= 2,50 x 10^-1

Le rapport molaire de l'aluminium à l'oxyde d'aluminium est donc de 2,50 x 10^-1.
