The a metal tank containing hydrogen gas has a pressure gauge that reads 575 psi, 120 pressure inside of the tank.
What is pressure gauge?
A device used to measure a fluid's (liquid or gas') state by calculating the force the fluid would apply to a unit area if it were at rest.
What is pressure?
The force of all gas particle/wall collisions divided by the surface area of the wall is the definition of pressure (P): One of the fundamental quantifiable variables.
Therefore, a metal tank containing hydrogen gas has a pressure gauge that reads 575 psi, 120 pressure inside of the tank.

Answer:
23 kPA
Explanation:
95kPa = 24kPA (CO2) + 48 kPa (N) + x kPa (O)
24kPA(CO2)+ 48kPA (N) = 72 kPA
95kPA - 72kPA= 23kPA (O)
The protons contribute significantly more to an atom's mass because sodium has an atomic number of 11, where the number of protons in a neutral sodium atom is equal to the number of electrons. In the first group or column of the periodic table, sodium is an alkali metal.
The sodium atom mass has 11 protons and electrons, and its outermost shell has one valence electron. Pure sodium has a high level of reactivity. Since it is such a soft metal, a knife may be used to cut it with ease. The chemical element sodium has the atomic number 11 and the symbol Na.

The last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).
<h3>What is an experiment?</h3>
The essence of an experiment is to be able to establish a cause and effect relationship. It is only when we carry out a carefully controlled experiment that we can say that x causes y because the data would support our findings.
After, we have carried out an experiment, the next step is to put the evidences together and then try to arrive at a logical conclusion for the experimental procedure.
Thus the last step (step 5) in the experiment is to write a conclusion for the experiment. (Option B).
