In order from the most likely to bind an oxygen to least likely;

Haemoglobin is more likely to bind oxygen if its other oxygen binding sites have already bound to an oxygen molecule. The higher the partial pressure of oxygen in the blood also makes it more likely that the hemoglobin will bind oxygen.

Hemoglobin is a protein-rich in iron that has an affinity (combining ability) to oxygen and with oxygen, it forms oxyhemoglobin in red blood cells. The amount of hemoglobin in normal blood is 15 grams per 100 ml of blood, and the hour is usually called "100 percent".

<h2>Further Explanation</h2>

Hemoglobin is a substance found in red blood cells. Hemoglobin is actually a globular protein in the form of 4 subunits, and each subunit contains hame.

Hemoglobin plays an important role in oxygen transport as long as it can re-bind oxygen. Hemoglobin tends to bind oxygen when the environment is full of oxygen and releases oxygen in a relatively low oxygen environment. This means hemoglobin takes oxygen in the lungs and releases it to tissues such as active muscle. In people who have normal hemoglobin, the capacity of the blood carries about 20 mL of oxygen per 100 mL of oxygen. In almost all situations, blood contains a lot of oxygen as it moves through the lungs.

Hemoglobin is carried by circulating red blood cells (erythrocytes). This circulation rotates for about 10 days containing approximately 3 x 10 red blood cells. A rough estimate of blood hemoglobin levels can be obtained from the amount of hematocrit or from the amount of blood by consuming each red blood cell that has normal hemoglobin

The heat produced by the metabolism reaction of muscle contractions releases a lot of acid & heat causes the body temperature to rise and the active cells need a lot of O2 to spur the release of O2 from OxyHb (Hb affinity towards O2 decreases) the curve shifts to the right.

Hypothermia causes slow cell metabolism so that the O2 needed by the tissue to release a small amount of O2 from Hb is also slow (Hb affinity for O2 decreases) and the hemoglobin oxygen dissociation curve shifts to the left.

CONCLUSIONS: Suppose a student titrated a sample of monoprotic acid of unknown concentration using a previously standardized sol
Zolol [24]

Concentration of unknown acid is 0.061 M

Given:

Concentration of NaOH = 0.125 M

Volume of NaOH = 24.68 mL

Volume of acid solution = 50.00 mL

To Find:

Concentration of the unknown acid

Solution: Concentration is the abundance of a constituent divided by the total volume of a mixture. The concentration of the solution tells you how much solute has been dissolved in the solvent

Here we will use the formula for concentration:

M1V1 = M2V2

0.125 x 24.68 = 50 x M2

M2 = 0.125 x 24.68 / 50

M2 = 0.061 M

Hence, the concentration of unknown acid is 0.061 M

emmasim [6.3K]

Answer:

Matter has different densities. Different food colorings have different densities. Those with a higher density will sink to the bottom and mix much easier than one with a lower density. The higher density also contains more particles making it easier to mix or give it a fuller color.
