How many hydrogen ATOMS are needed to produce 2 water (H2O) molecules? HINT: ATOMS not molecules

Just 4...

Explanation:

There are 2 hydrogen atoms in 1 water molecule, so in 2 water molecules would have 4 hydrogen atoms.

*booyah*

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

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
