Answer:
V is proportional to StartFraction n over p EndFraction.
Explanation:
Let us remind ourselves of the statements of both Boyle's law and Avogadro's laws.
Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
Avogadro's law states that at the same temperature and pressure, equal volumes of gases contain equal number of molecules.
Hence ;
V α 1/P (Boyle's law)
V α n (Avogadro's law)
V α n/p (combination of Boyle's law and Avogadro's law)
Answer:

Explanation:
I don't know what dimensional analysis is but I just did multiplication.
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)

1.1kg = 1100g
If each paper clip is 0.88g : 1100 / 0.88 = 1250
1250 paper clips in the box
