Answer:
Explanation:
to put this plainly after putting strong electrolytes in water they dissolve to nothing but ions they give you an example and definition of a strong electrolyte I suggest you read those and see if you come up with what I gave you they also tell you that not all strong electrolytes dissolve as strongly as others that are in the example.
Answer:
Ca2+ represents an ion with 20 protons and 18 electrons.
Explanation:
Answer:
Each principal energy level above the first contains one s orbital and three p orbitals. A set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. Therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

Answer:
The longest wavelength of radiation with enough energy to break a carbon–carbon bond is 343.75 nm.
Explanation:
E = hc/λ
E: energy = 348 000 J / 6.022 x 10²³ = 5.7788 x 10⁻¹⁹ J
h: Planck's constant = 6.62607004 × 10⁻³⁴ J.s
c: speed of light = 299 792 458 m / s
λ: wavelength
λ = hc/E
λ = (6.62607004 × 10⁻³⁴ J.s x 299 792 458 m / s) / 5.7788 x 10⁻¹⁹J
λ = 3.4375 x 10⁻⁷ m
λ = 343.75 nm
