Balance HNO3 + H2O + C2H3NaO2 = NaNO3 + C2H6O3 Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, e...
3As2S3+4H2O +28HNO3=28NO +6H3AsO4+9H2SO4. 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, yo...

nucleation involves sulfuric acid (H2SO4) over almost all the troposphere8. However, binary nucleation of H2SO4–H2O is slow and, so, ternary or multicomponent nucleation with extra vapours such as ammonia (NH3)9and organics10,11is necessary to account for observed new-particle-formation rates...
Furthermore, reaction probability measurements reveal that the chlorine radical precursors are formed readily at polar stratospheric temperatures not just on NAT and ice crystals, but also on liquid H$_2$SO$_4$ solutions and on solid H$_2$SO$_4$ hydrates. These results imply that the ...
