1. Carbon(II) oxide, also known as carbon monoxide, is a colorless, odorless, and highly toxic gas with the chemical formula CO. It is formed when carbon or carbon-containing compounds burn in a limited supply of oxygen (incomplete combustion). One method of its preparation in the laboratory is by the dehydration of methanoic acid (formic acid) using concentrated sulfuric acid as a dehydrating agent: HCOOH(l) conc. H_2SO_4 CO(g) + H_2O(l) 2. Here are two physical and two chemical properties of Carbon(IV) oxide (carbon dioxide): Physical Properties: It is a colorless and odorless gas. It is denser than air. Chemical Properties: It is a non-supporter of combustion (does not burn and extinguishes flames). It reacts with water to form carbonic acid (H_2CO_3), making it slightly acidic. 3. An acid is a substance that produces hydrogen ions (H^+) when dissolved in water (Arrhenius definition) or is a proton (H^+) donor (Brønsted-Lowry definition). A base is a substance that produces hydroxide ions (OH^-) when dissolved in water (Arrhenius definition) or is a proton (H^+) acceptor (Brønsted-Lowry definition). Example of an acid: Hydrochloric acid (HCl) Example of a base: Sodium hydroxide (NaOH) 4. The balanced chemical equation for the reaction between hydrochloric acid and sodium hydroxide is: HCl(aq) + NaOH(aq) NaCl(aq) + H_2O(l) 5. A salt is an ionic compound formed when the hydrogen atom of an acid is replaced by a metal ion or an ammonium ion. It is typically formed from the reaction of an acid with a base, metal, or carbonate. Two methods of preparing salts are: Neutralization reaction: Reacting an acid with a base (e.g., HCl + NaOH NaCl + H_2O). Reaction of an acid with a metal: Reacting a dilute acid with a reactive metal (e.g., Zn(s) + H_2SO_4(aq) ZnSO_4(aq) + H_2g)). Drop the next question! 📸
