Answer: Option (b) is the correct answer.

Explanation:

Since, the chemical formula of acetic acid is CH_{3}COOH. And, symbol which represents a carbon atom is C, hydrogen atom is represented by H and an oxygen atom is represented by O.

Therefore, as in a molecule of acetic acid there are total 2 carbon atoms, 4 hydrogen atoms and total 2 oxygen atoms.

Thus, we can conclude that there are 2 atoms of the element carbon (C) are in a molecule of acetic acid.

How can an abiotic factor affect a biotic factor
xenn [34]
Biotic and abiotic factors are the environmental conditions that the organisms have to face to live in a specified environment.

-Abiotic factors-
Abiotic factors are the physical and chemical conditions of an environment. For example : heat, salinity, pressure, light, wind, pH ...

-Biotic factors-
Biotic factors are all the biological conditions of an environment for a specie/taxa. It can include prey and predator abundance, available food amount, available space, intra and interspecific competition...

The development of organims is under the control of abiotic factors. Some are adapted to heat, cold etc ... The abiotic factors will define which organisms are able or not to live in a specified place.

The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment.
So, the abiotic factors are controling the biotic factors of an environment.

If the pressure in the room is 759.2 torr and the vapor pressure of water is 23.8 torr, what is the pressure of hydrogen gas in
Gwar [14]

The partial pressure of Hydrogen gas can directly be calculated by simply taking the difference of the overall pressure and the vapour pressure of water. That is:

 

P (H2 gas) = 759.2 torr – 23.8 torr

<span>P (H2 gas) = 735.4 torr</span>
