Which describes the role of oxygen in photosynthesis and cellular respiration?

1 answer:

4 0

photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.

<u>Answer:</u> The total number of electrons that must be shared between carbon and oxygen atoms are 8.

<u>Explanation:</u>

A covalent compound is formed when sharing of electrons takes place between the atoms forming a compound.

Carbon is the 6th element of the periodic table having electronic configuration of $1s^22s^22p^2$

This element requires 4 electrons to complete its shell.

Oxygen is the 8th element of the periodic table having electronic configuration of $1s^22s^22p^4$

This element requires 2 electrons to complete its shell.

So, in order to complete the octet of both the elements, 2 oxygen atoms are required for 1 carbon atom.

Hence, the total number of electrons that must be shared between carbon and oxygen atoms are 8.

A 50°C solution has a pH of 3.30. At this temperature, Kw = 5.48 x 10 9. What is the pOH of the solution?

sammy [17]

Answer:

9.93

Explanation:

Your value for Kw is incorrect. The correct value is 5.48 × 10^-14.

pH + pOH = pKw

3.30 + pOH = -log(5.84 × 10^-14) = 13.23

pOH = 13.23 - 3.30 = 9.93

The pOH of the solution is 9.93.

Calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.
