H2 is neutral. It does not affect pH.
No, a pH of 1.3 to 2.0 would be acidic, though such a pH could be achieved with either a strong or a weak acid.

Given/Known:1mole of H2 = 2.01588g H21mole of H2 = 6.022 x 1023 molecules H21) Convert molecules of H2 to moles of H2 by doing the following calculation.9.4 x 1025 molecules H2 x (1mol H2/6.022 x 1023 molecules H2) = 156mol H22) Convert the moles of H2 to mass in grams of H2.156mol H2 x (2.01588g H2/1mol H2) = 314g H2
H2(g) is the compound in the gaseous state in the given reaction.
The balanced equation is as follows: Zn(s) + 2HCl(aq) --> ZnCl2(aq) + H2(g)
pH depends on:strength, (H2 is very, very, very, very weak!; much and much more weaker than H2O) ANDconcentration (H2 is very, very, very insoluble in water, so very, very, very low concentration)Thus pH will be (about?) 7.0
No, a pH of 1.3 to 2.0 would be acidic, though such a pH could be achieved with either a strong or a weak acid.
H2+ has a stronger bond than H2. The addition of a positive charge to the H2 molecule increases the attraction between the two hydrogen atoms, resulting in a stronger bond.
The product of H2 is hydrogen gas (H2) composed of diatomic molecules.
