Almost all of the oxygen (O2) one consumes in breathing is converted to:
a. acetyl-CoA.
b. carbon dioxide (CO2).
c. carbon monoxide and then to carbon dioxide.
d. none of the above.
e. water.
Almost all of the oxygen (O2) one consumes in breathing is converted to: b. carbon dioxide (CO2).
When we breathe in oxygen, it is used in cellular respiration, which is the process by which our body converts glucose and oxygen into energy in the form of ATP. In the process, the oxygen is combined with the hydrogen atoms from glucose to form water, and the carbon atoms from glucose are converted to carbon dioxide (CO2) as a waste product. Therefore, almost all of the oxygen that one consumes in breathing is converted to carbon dioxide (CO2).Breathing is the process by which an organism takes in oxygen and expels carbon dioxide. In humans and other mammals, this process is accomplished through the respiratory system, which includes the nose, trachea, bronchi, and lungs. When we inhale, air is drawn into the lungs through the nose or mouth, passing through the trachea and bronchi before reaching the alveoli, which are small air sacs in the lungs where gas exchange occurs.

The molar mass of nitrogen gas is 28. 00 g/mol
Show all steps in the solution of this question, including proper units, for full credit
3.88 grams of sodium azide are required to form 5.00 g of nitrogen gas.
In order to determine how many grams of sodium azide are required to form 5.00 g of nitrogen gas, we can use the balanced equation for the reaction:
2NaN3 (s) → 2Na (s) + 3N2 (g)
We can start by converting the given amount of nitrogen gas to moles:
5.00 g N2 x (1 mol N2 / 28.00 g N2) = 0.1786 mol N2
We know that the reaction produces 3 moles of N2 for every 2 moles of NaN3 that are used, so we can use the following ratio to find the number of moles of NaN3 required:
0.1786 mol N2 / 3 mol N2 = 0.0596 mol NaN3
Finally, we can convert moles of NaN3 back to grams using the molar mass of NaN3:
0.0596 mol NaN3 x (64.99 g NaN3 / 1 mol NaN3) = 3.88 g NaN3

The student collected data on the mass of each artificial cell. The student predicted that the cell in the beaker with 25% sugar solution would have the greatest change in mass after 24 hours. The student's prediction would be correct.
Why would the prediction of the experiment be correct?The artificial cell placed in the beaker with 25% sugar solution would likely have the greatest change in mass after 24 hours because of osmosis.
Osmosis is the movement of water across a semi-permeable membrane from an area of high water concentration to an area of low water concentration. In this case, the artificial cell has a semi-permeable membrane that allows water to pass through, but not sugar.
The 25% sugar solution in the beaker is less concentrated than the sugar solution inside the artificial cell, so water will move from the beaker into the cell, causing the cell to swell and increase in mass.
On the other hand, the artificial cells in the beakers with 0% and 12.5% sugar solutions will have less of a change in mass as the solution outside of the cell is more concentrated than inside the cell.

At equivalence, the number of moles of methylamine and HCl are equal, and the pH of the solution is 4.76.
At equivalence, the number of moles of methylamine and HCl are equal, so we can use the equation:
n(CH3NH2) = n(HCl)
0.2108M * 110.0mL = 0.4152M * V
V = 52.4mL
Total volume of the solution: 110.0mL + 52.4mL = 162.4mL
We can use the Henderson-Hasselbalch equation to calculate the pH at equivalence:
pH = pKb + log([CH3NH2]/[HCl])
pH = 3.36 + log(0.2108M/(0.2108M + 0.4152M))
pH = 3.36 + log(0.2108M/(0.6259M))

Does reactivity increase or decrease from left to right among elements in a period?
Period. As you move from either the left to the right, reactivity rises. Group reactivity diminishes from top to bottom.
As you move from left toward right across a period, responsiveness declines. Higher reactivity is caused by the ease with which electrons can be given or snatched away as you move further to the left as well as along the periodic chart.
This is because the size of both the atomic radius expands as the quantity of electronic energy does. reducing the attractiveness of other elements' valence electrons lowers reactivity.
It happens because there are more valence shells and less interaction among valence pairs of electrons. Consequently, the propensity to take electrons from some of the other atoms declines. Atoms get more electronegative as they move through a period.

ny = (22.4 L * 1 mol/22.4 L) = 1 mol
Therefore, nx = 1 mol and ny = 1 mol.
This means that if the reaction is carried out in a 22.4 L container, the initial amounts of x and y required to form solid xy are 1 mol of x and 1 mol of y.

Answer:
30.5%
Explanation:
A 0.95 M solution of 10.0 mL Al(OH)3 is neutralized using a 2 M solution of H2SO4. How much H2SO4 was needed
H2SO4 has a molecular weight of 98 g/mole. 98% concentrated sulfuric with a density of 1.84 g/mL is the usual source.
We would need 98 g for a 1 M solution in 1 L, but because this is for 500 mL, just 49 g of H2SO4 will be needed. Common concentrations of sulfuric acid are 78, 93, or 98 percent. Pure anhydrous sulfuric acid does not exist in nature due to its affinity for water. 35% sulfuric acid Fertilizers like ammonium sulfate and super-phosphate of lime are produced using solution. In the production of hydrochloric acid, sulfate salts, synthetic detergents, dyes & pigments, and medications, it is frequently employed.
