Chemical bonding may involve any of the following except the 1. change in mass in a chemical reaction
2. unequal sharing of a pair of electrons between two nonmetals
3. electrostatic attraction between two ions
4. transfer of an electron from one atom to another

Number 1 is wrong it doesn't change the mass

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

the maximum mass of nh3 is nh3 in grams
