All the elements in one group have the same number of valence electrons.
The pressure of the nitrogen gas produced is determined as 44.77 atm.
<h3>
What is the pressure of the Nitrogen gas?</h3>
The pressure of the nitrogen gas is determined from ideal gas equation, as shown below;
PV = nRT
P = nRT/V
where;
- n is number of moles = 2 moles
- R is ideal gas constant = 0.08205 L.atm/mol.K
- T is temperature = 68⁰C = 68 + 273 = 341 K
- V is volume = 1.25 L
P = (2 x 0.08205 x 341)/(1.25)
P = 44.77 atm.

The most accurate answer is A.
Bacterial cells are generally very small, almost 10 times smaller than most animal and plant cells. Most bacterial cells measure about 0.2 to 10 microns or micrometers which in inches is 0.0000079 to 0.00039.
One of the reasons that bacterial cells are so small is that they require a large surface area to volume ratio to be able to take in nutrients. They take in nutrients from their surroundings through the process of diffusion.
Explanation:
Atomic number (Z) = Number of the protons
It means that if the atomic number of C is 6, it implies that the number of protons in carbon is 6 too.
Mass number (M) = Number of the protons + Number of the neutrons
It means that if the atomic mass of C is 12, it implies that the number of protons and the neutrons in carbon is 12.
