Which reaction below represents the second ionization of sr? a. sr(g) → sr⁺(g) + e⁻ b. sr2⁺(g) + e⁻ → sr⁺(g) c. sr⁺(g) + e⁻ → sr(g) d. sr⁻(g) + e⁻ → sr2⁻(g) e. sr⁺(g) → sr2⁺(g) + e⁻?

h let me think

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
