Why are oxygen and hydrogen two of the most abundant elements in living things

Physics
1 answer:
katen-ka-za [31]3 years ago
6 0

Answer:

Oxygen and Hydrogen are the most abundant elements found in living beings because of their combination to form water together that builds the 70% of the living body, oxygen being used in respiration and Hydrogen being used to form other compounds as it has the simplest structure and least requirements to bond with other elements.

Explanation:

To build something, it's is important to start with the simplest formation and proceed to the complex ones. Same case applies on living beings. With the creation of all living bodies, two of the most abundant elements Hydrogen and Oxygen tends to volunteer in the formation of living bodies. Their simplest structure and least requirements to bond easily with other elements also make them suitable for the creation of living bodies.

Hydrogen consisting of only one proton and one neutron, easily collaborates with other elements and forms the complex compounds. Whereas, oxygen being processed under the respiration system, helps in developing important organs and compounds. And, most importantly not to forget point is that they both combine to make the significant compound of the living body i.e water. However, Carbon, Nitrogen and other traces are also present in the living beings but these two serve as the saviors of the war.

object carries a charge of -8.1 µC, while another carries a charge of -2.0 µC. How many electrons must be transferred from the
LenKa [72]

Number of electrons transferred: 1.91\cdot 10^{13}

Explanation:

The charge on the first object is

Q_1 = -8.1\mu C

while the charge on the 2nd object is

Q_2=-2.0 \mu C

When they are in contact, the final charge on each object will be

Q=\frac{Q_1+Q_2}{2}=\frac{-8.1+(-2.0)}{2}=-5.05 \mu C

So, the amount of charge (electrons) transferred from the 1st object to the 2nd object is

\Delta Q = Q_1 - Q = -8.1 -(5.05)=-3.05 \mu C = -3.05\cdot 10^{-6}C

The charge of one electron is

e=-1.6\cdot 10^{-19}C

Therefore, the number of electrons transferred is

N=\frac{Q}{e}=\frac{-3.05\cdot 10^{-6}}{-1.6\cdot 10^{-19}}=1.91\cdot 10^{13}

If there is "waste" energy, does the Law of Conservation of Energy still apply? please don't type something random if so i'll ju
FinnZ [79.3K]

Explanation:

Yes, the law of conservation of energy still applies even if there is waste energy.

The waste energy are the transformation products of energy from one form to another.

According to the law of conservation of energy "energy is neither created nor destroyed by transformed from one form to another in a system".

But of then times, energy is lost as heat or sound within a system.

  • If we take into account these waste energy, we can see that energy is indeed conserved.
  • The sum total of the energy generated and those produced will be the same if we factor in other forms in which the energy has been transformed into.
