Indicate the si base units or derived units that are appropriate for the following measurements:
(a) the length of a marathon race(26 miles 385 yards)
(b) the mass of an automobile
(c) the volume of a swimming pool
(d) the speed of an airplane
(e) the density of gold
(f) the area of a football field
(g) the maximum temperature at the south pole on april 1,1913

The units of SI: meter, kilogram, second, Kelvin

Explanation:

(a) The length of a marathon race: meter (m)

(b) The mass of an automobile : kilogram (kg)

(c) The volume of a swimming pool : cubic meter (m^3)

(d) The speed of an airplane : (m/s)

(e) The density of gold : (kg/m^3)

(f) The area of a football field : square meter (m^2)

(g) The maximum temperature at the South Pole on April 1,1913: Kelvin (K)

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
