Answer: Acidic liquids have low pH levels. Many fruit juices qualify as acidic liquids. Some of the more acidic fruit juices are orange juice, lemon juice, grapefruit juice, tomato juice and red currant juice.

Answer:
Iron is oxidized to form rust.
Explanation:
Consider the reaction; 4Fe + 302------>2Fe2O3, we can see that iron is being oxidized to iron III oxide. Rust is the common name of iron III oxide.
Rusting is an electrochemical process, iron rusts when it comes into contact with air and water because electrochemical cells are set up at the surface of contact.
Iron usually functions as the anode in the electrochemical process. This process leads to the formation of iron III oxide. Rust is soft and breaks off easily thereby exposing the metal below the surface to further rusting.
Explanation:
<h2>symbols, abbreviations, or full names for units of length, Formula of ammonium carbonate: (NH4) 2CO3 Molar mass of ammonium carbonate = 96.11 g/mol Finding moles of ammonium carbonate: (6.975 g) / (96.11 g/mol) = 0.07257 moles Since there are 2 moles of ammonium ions in every mole of ammonium carbonate</h2>
The percent yield is 45 %.
