Which of these equations is balanced?
a. 3 h2so4 + 2al → al2(so4)3 + 3h2
b. 2kcl + pb(no3)2 → 2kno3 + pbcl2
a. a
b. b
c. a and b
d. neither

Both are already balanced. So, your answer would be: C. a and b

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
