31
A dalton is the same as an atomic mass unit. And an atomic mass unit is approximately the mass of a nucleon (proton or neutron) such that the mass is 1 g/mol. So in this problem you have 15 protons and 16 neutrons, so the number of daltons is 15 + 16 = 31.
The complete statement will be "Support gases system are subject to the same hazards as, present in any piped medical gas system with the additional hazard of higher pressure"
<h3>What are gas systems?</h3>
Generally, A gas system is simply defined as an assemblage of tubes, used for gas reticulation and circulation.
In conclusion, a higher pressure will be experienced as an additional hazard to the medical gas system.

Answer:
P1V1 = P2V2
(1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm
Answer:
Nitrogen
Explanation:
It is the most abundant gas in the atmosphere.
Answer:
The correct order is: Fluorine; Oxygen; Nitrogen; Carbon; Hydrogen; Sodium.
Explanation:
The electronegativity in the periodic table increases to the right in a period and up in a group. We can figure out the electronegativity of each element according to its electron configuration:
Carbon: [He] 
Fluorine: [He] 
Hydrogen: 
Nitrogen: [He] 
Oxygen: [He] 
Sodium: [Ne] 
The period of a chemical element is given by the last energy level of electron configuration.
The group of a chemical element is given by the amount of electrons in the last energy level of electron configuration.
Therefore,
Carbon: Period 2 Group 4
Fluorine: Period 2 Group 7
Hydrogen: Period 1 Group 1
Nitrogen: Period 2 Group 5
Oxygen: Period 2 Group 6
Sodium: Period 3 Group 1
Electronegativity increases when the number of the group increases.
Electronegativity increases when the number of the period decreases.
In conclusion, Fluorine has the greatest number of group and Sodium has the lowest number of group (also it has a greater number of period than hydrogen, so it is less electronegative than hydrogen)
