In this equation 2mg+o2=2mgo what is the subscript of the oxygen molecule

The subscript of the O₂ molecule is the small “2” at the lower right-hand corner of the “O”.

Explanation:

A subscript is a letter or a number that is written below the line.

In chemistry, a subscript after an atomic symbol tells you how many of those atoms are in the unit.

Thus, the subscript in O₂ tells you that there are two oxygen atoms in a molecule of oxygen.

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.

the correct answer would be b) volume versus temperature, because they are also directly proportional.
