Al(s) + HCl → AlCl3 (aq) + H2(g) find the oxidation number for each element

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

c (diamond),

sio2 (quartz)
