Why doesn't it matter which nonradioactive isotope of oxygen you breathe?

Chemistry

Answer:

Because they all have the same chemical properties and can be used for breathing.

Explanation:

Conceptually, isotopes are atoms that have the same number of protons, that is, they are distinct species of the same element, differing only in the number of masses and neutrons.

Oxygen is a colorless, odorless and tasteless gas, poorly soluble in water, present in nature as three stable isotopes: oxygen 16 (present in 99.75% of occurrences in the environment); oxygen 17 (0.37% of occurrences) and oxygen 18 (0.20% of occurrences). All forms of non-radioactive isotope of oxygen can be breathed by living beings, because they all use the same kind of chemical properties, so all have the same function.

Isotopes of an element have same atomic number (number of protons) but vary in the mass number (number of neutrons). The chemical reactivity of an element is not affected by the change in mass number. So, for stable isotopes of Oxygen, (Oxygen-16, Oxygen-17 and Oxygen-18) the biochemical pathway of oxygen breathed in during respiration remains unaffected even with different isotopes. Only the radioactive isotopes of oxygen when breathed in may cause serious health hazards as they emit radiations that may damage the internal organs in the body.

In the following equation, which element has been oxidized?
Bumek [7]

The  element  that has  been  oxidized   is Al  (  Answer  A)


Explanation

 if  the oxidation number of an element is greater in the product side than the reactant  side  then the element   has lost  the electrons . This mean  that  the element  has been oxidized.

Al  is  oxidized  because  it move  from  oxidation  state  Zero(0)  in reactant side  to  oxidation state 3⁺  in product  side.

This  implies  that  Al  loses  3  electrons.

Because CSF is continually being made at the rate of about 20 mL/hr, it has to exit back into the bloodstream by being reabsorbe
klasskru [66]

Answer:

It is called the superior sagittal sinus.

Explanation:

The superior sagittal sinus which is often called the superior longitudinal sinus) is situated in the human head. It is an unpaired region in the human head around the attached margin of the falx cerebri. It main function is to ensure that blood is removed from the lateral parts of the anterior cerebral hemispheres and transferred to the confluence of sinuses. It also has a triangular cross sectional area and with a left/right lateral angles at its junctions. Therefore, The right answer is the the superior sagittal sinus.

The standard free energy that is required for the sodium-potassium ATPase to pump two K ions into the cell and three Na ions is
BabaBlast [244]

Answer:

Explanation:

This apparent disparity of the free energy can be taken into account because:

the free energy produced by the hydrolysis of one ATP is adequate enough under psychological circumstances.

The Na-K ATPase aids the pumping of Na+ ions out of the cell and K+ ions into the cell. These actions occurring against their potential(concentration) gradients, which may be produced by hydrolyzing one ATP molecule.
