Constant temperature T The, The IUPAC name of an element with atomic number 119 is. Therefore, Fady is incorrect and only Lobna is correct. Q2) Name the important scientists and their studies which led to the discovery of the components of Q3) Explain Lavoisers experiment which provided evidence to the discovery of components in air. It's prepared by using a hydrogen source and combining it with oxygen. I would definitely recommend Study.com to my colleagues. 3. Hydrogen peroxide is used for stain removal, as a cleanser and as a disinfectant. succeed. Therefore, when oxygen and air are mixed, oxygen will fall to the bottom. We also know that a catalyst is a substance whose quantity and structure do not change during a chemical reaction. The other product is water. sodium peroxide. in certain plants. 2HSO4(aq) [Electrolysis] HO3SOOSO3H(aq) [Hydrolysis] 2HSO4(aq)+2H+(aq)+H2O2(aq), 2HSO4 H2S2O8+ 2e Peroxodi Sulphuric Acid [Marshalls acid], H2S2O8+ H2O H2SO5+ H2SO4 Peroxomono Sulphuric Acid [Caros acid], Auto-Oxidation Method of Preparation of H2O2.
