What is produced when an acid reacts with water? a. oxygen gas b. hydronium ions c. hydrogen gas d. an indicator

acids are species that release H⁺ ions/protons. Hydrogen ions are also called protons since they have no electron and only proton.

When hydrogen ions are added to water - H₂O, oygen tends to donate one of its lone pairs to H⁺ which is electron deficient in the form of a dative bond.

thereby making a hydronium ion.

written as H₃O⁺.

when neutral H₂O donates an electron pair to H⁺, the overall charge of the ion becomes positive.

answer is B. hydronium ions

Diffraction and Interference

Explanation:

The light sometimes acts like a particle and sometimes like a wave, yet the diffraction and interference are proof of the light's wave nature.

First of all, as a definition, the interference is an effect caused by superposition of two systems of waves (from two different sources). (As an example, the interference -distortion- in radio waves)

The diffraction, by the other hand, refers to several events that occur when a wave meets an obstacle. (usually described as a bending of waves around obstacles -likethe water waves- and in other cases as the dissemination of waves, once they passed small openings)
