Based on the information in the table, which conclusion about the chemical reactivit of these elements is valid? Boron is the most reactive because it has the least number of protons. Potassium is the most reactive because it has the least number of valence electrons. Silicon is the most reactive because it has an equal number of protons and neutrons. Gallium is the most reactive because it has many more neutrons than protons. ​

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

it's all four options.

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.
