The most prevalent PSCs form at temperatures several degrees above the ice frost point and are believed to consist of HNO$_3$ hydrates; however, their formation mechanism is unclear. Results of laboratory experiments are presented which indicate that the background stratospheric H$_2$SO$_4$/H...
In a formal sense, the new-particle-formation mechanism could be one of two types: formation of stable H2SO4–NH3clusters, followed by nano-Köhler-type activation by nitric acid and ammonia16; or else true synergistic nucleation of nitric acid, sulfuric acid and ammonia9. In a practical s...
To calculate the stoichiometry of FeS + H2SO4 + HNO3 = Fe2(SO4)3 + NO2 + H2O you must balance the equation to find the stoichiometric mole ratio of each compound. The equation can be balanced using the chemical equation balancer. The stoichiometry calculator above ...
A reaction mechanism was proposed and was shown to reasonably elucidate the observed rate phenomena.doi:10.1002/prep.19900150405Tai-Kang LiuChung Shan Institute of Science and Technology, Lung Tan, Taoyuan, Taiwan (Republic of ChinaYan-Nian Shyr...

Vacuum pyrolysis of acid-impregnated (H2SO4, HCl, HNO3) purified cellulose was carried out at a heating rate of 10°C min−1 and a constant final temperature (380°C). The average pressure was 130 Pa in the retort. The objective was to study the influence of inorganic ion content on...
6FeO +9H2SO4+2HNO3=3Fe2(SO4)3+2NO +10H2O. Enter the amount of any of the substances to determine the ideal amounts to maximize the theoretical yield of the reaction. To find the limiting and excess reagents when a non-ideal amount of each substance is used, y...
Decreased reaction rates at > 7 molL1 H2SO4 are attributed to high solution viscosities and the formation of fluorosulfuric acid. Generally, in HF-HNO3-H2SO4/H2O etching mixtures a reduced dissociation of nitric acid, the formation of nitronium ions, the solubility of neutral nitrogen ...
