one million) H2(g) + Cl(g) --> 2HCl (aq) 2) SO2(g) + H2O(l) --> H2SO3 3) 4Fe(s) + 6O(g) --> 2Fe2O3 (s) 4) H2O2 (aq) --> H2(g) + O2(g) whilst doing those you purely could comprehend what the oxidation states of the atoms are. then you definately can write the chemical reaction and stability it utilising stoichiometry. the foremost to balancing equations is to confirm you may comparable volume of each and every species on the two factors. Its least complicated to split them out and count sort them for my section. synthesis reactions one million) HCl (aq) + Al(s) --> AlCl3 (s) + H2(g) 2) H2O (l) + Na(s) --> NaOH (aq) + H2(g) 3) 2Mg(s) + Pt(OH)4 --> 2Mg(OH)2 + Pt(4+) With those, you're doing what's named a single displacement reaction. you purely transpose the metals. If hydrogen is being replaced, commonly that is going to sort hydrogen gas. confirm you verify the periodic table to be certain if the steel you're changing with is greater reactive then the only that it may be changing. the better and the greater left the component, the greater reactive with non-metals that is going to likely be. decomposition O2 --> 2O(2+) PCl5 --> P(5+) + 5Cl(-) For the states, any steel by utilising itself that doesnt have a cost on that is going to likely be interior the solid state. commonly ionic species and metals with a cost (like Pt(4+) would be interior the aqueous state (aq). Water would be liquid (l), and hydrogen would be gas (g). Neutralization one million) HCl(aq) + LiOH (aq) --> LiCl(aq) + H2O(l) 2) 2H2SO4 (aq) + 4NaOH (aq) --> 2Na2SO4 (aq) + 4H2O (l) 3) BaCl2 (aq) + Na2CrO4 (a) --> BaCrO4 (aq) + 2NaCl (aq) nuetralization reactions are the comparable different than its greater like a double alternative reaction. Acids and bases like the 1st one will consistently sort a salt and water. Double displacement reactions one million) 2FeCl3 (aq) + 3Na2SO4(aq) --> 6NaCl (aq) + Fe2(SO4)3 (aq) only turn the two metals and stability. pay interest to oxidation states on the species. you're welcome for doing all your hw. you greater effective provide me terrific answer ;)
