Suppose you have 1000 mL of a solution of hydrochloric acid (HCI) that is 12 M in concentration. If you added 350 mL to this solution, what would be the resulting concentration of HCI?

True is ur answer : )

Answer is: hydrogen is being oxidized.chemical reaction: co₂ + h₂ → co + h₂o.oxidation half reaction: h₂ → 2h⁺ + 2e⁻.reduction half reaction: c⁺⁴ + 2e⁻ → c⁺².oxidation is increase of oxidation number, hydrogen change oxidation number from neutral charge (in molecule of hydrogen) to oxidation number +1 (in water).

At a given pressure, gas particles with smaller masses move faster.
