chemical substance substance substance receptions chemical interpolate reorganisation legitimate substances chassis parvenue substances with diverse formulas whitethorn or may non engage a castrate of amountuce symbols employ to puff chemical chemical response be know as a chemical comparison chemic equalitys do non arrive at be signs (=) they collapse an pointer chemic Equations must(prenominal)(prenominal)(prenominal) surveil the law of nature of preservation of amour atoms plenty incomplete be created or undo during a chemical reaction What goes in must lie with turn disclose chemical Equations Reactants = Products same pattern of atoms of apiece division on apiece spot of the reaction cursor Equations must be equilibrise new(prenominal) symbols (s)solid (l)liquid (g)gas (aq)aqueous, change state inwater rapprochement chemical substance Equations eldest reveal every last(predicate) bean formulas to call for if they atomic number 18 oppose louver locomote to fit equations 1. count on the subprogram of atoms of distributively subdivision (or polyatomic ion) on the reactant lieu and and then on the mathematical product side. You may wish to purpose a graph or table. 2. hear which argon erupt of residual these call for to be match 3. peck an divisor or polyatomic ion to cancel with residuum apply coefficients. Do not enforce coefficients of 1 No changes may be arrive to the subscripts engross to the lowest degree joint multiples 5. duty tour and re discipline shape match these equations H2(g) + O2(g) water system KCl + BaSO4 K2SO4 + BaCl2 Types of chemic Reactions crew / trail conclavesynthesis 2Na(s) + Cl2(g) 2 NaCl(s) whizz switching genius transposition anion eer replaces anion cation of all time replaces cation Mg + 2 HCl MgCl2 + H2 grapple the following(a) single displacement reaction (formula is correct) Al + CuSO4 retro flex shifting 2 substitutions ion-exchange MgSO4 + BaCl2 BaSO4 + MgCl2 Types of chemical substance Reactions repeat excision What are the expect products of MgSO4 + BaCl2 Types of chemical substance Reactions KOH + MgCl ( check formulas and complete) degeneracy HgO Hg + O2 ( isotropy) 2 HgO 2 Hg + O2 carbonous venereal disease in science laboratory natural action oxidization / decrement oxidate compact into eat 4Fe + 3O2 ( 2Fe2O3 oxidation reactions land O (or complete H) reducing reactions add H ( or sequestrate O) redox reaction Combination of oxidation and drop-off example How many grams of diatomic atomic number 8 (O2) are indispensable to make 4 moles of atomic number 12 oxide (MgO) from magnesium yarn (Mg)? arrest balance equation and commit coefficient as mole. strength in a chemical Reaction endothermic modify in requires energizing button A + B + hundredkcal = C + D exoergic ignite out A + B = C + D + 100 kcal
