Answer:
N2 = 588.95 mm Hg
O2 = 158.36 mm Hg
Ar = 6.787 mm Hg
Explanation:
Their percentage represents their mole fraction.
N2= 78.1% = 0.781
O2 = 21.0% = 0.21
Ar = 0.9% = 0.009
Barometric pressure is 754.1 mm Hg
Partial pressure for each will be,
For N2 = 0.781 x 754.1 = 588.95 mm Hg
For O2 = 0.21 x 754.1 = 158.36 mm Hg
For Ar = 0.009 x 754.1 = 6.787 mm Hg
For the answer to the question determine the total charge of the boron if t<span>he nucleus of one boron atom has 5 protons and 4 neutrons. The answer to this question is +5 for the charge of the boron.

Because the alkali metals are the group 1 metals, they have only 1 valence electron that they want to lose, and the halogens are the group 17 nonmetals, they want to gain 1 valence electron to become stable.
The sodium-potassium pump does not run out of ions since ion exchange is essential for the action potential to take place and to maintain homeostasis.
The cell has variable concentrations of different substances compared to the environment that surrounds it, with significant differences with sodium and potassium.
- The main function of the sodium-potassium pump is to maintain homeostasis of the intracellular medium, controlling the concentrations of these two ions.
- In order to carry out the adequate exchange of sodium and potassium ions in the extra and intracellular medium, the cells need an active transport process that is carried out thanks to the sodium potassium pump.
- This process is needed for the maintenance and functioning of cells, and it is essential for the action potential to be executed, necessary for the transmission of electrical impulses from neuron to neuron.
Therefore, we can conclude that the sodium potassium pump produces an exchange of potassium ions for sodium ions which keeps the cellular system functioning properly.
