Answer:
a) blue vitriol: copper (II) sulfate pentahydrate, b) slaked lime: calcium hydroxide, c) oil of vitriol: Sulfuric acid, d) washing soda: sodium carbonate, e) muriatic acid: hydrochloric acid, f) epsom salt: magnesium sulfate, g) chalk: calcium carbonate, h) dry ice: carbon dioxide, o) baking soda: sodium bicarbonate, j) lye: sodium hydroxide.
Explanation:
Answer is: H₂O → H⁺ + OH⁻.
Water dissociates (autoionization) to form hydrogen ions (H⁺) and hydroxide (OH⁻) ions. The protons (H⁺) hydrate as hydroxonium ions( H₃O⁺).
The Kw (the ionic product for water) at 25°C is 1·10⁻¹⁴ mol²/dm⁶ or 1·10⁻¹⁴ M². Concentration of hydrogen ions and hydroxide ions in pure water are the same.
Answer:
what does it mean?
if u could tell it to me...i would be thankful to ya

For that you have to use the Aufbau principle
For example, writing the electronic configuration of Fe(28)
I recommend that you memorize the aufbau principle. Once you learn it, you don’t need anything else except the atomic number of the element to write it’s electronic configuration.
