nter your answer in the provided box. Nitric acid (HNO3) is used in the production of fertilizer, dyes, drugs, and explosives. Calculate the pH of a HNO3 solution having a hydrogen ion concentration of 0.39 M. pH

Explanation:

pH = - log[ H⁺ ]

[ H⁺ ] = .39

pH = - log .39

= - log (39 x 10⁻²)

= 2 - log 39

= 2 - 1.59

=  .4 1

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
