Name:____________________ Per:___ Writing, Balancing, & Identifying Chemical Reactions 1. a) List the 7 diatomic elements: b) What does it mean to be diatomic? Writing Chemical Reactions: a) Write the correct formulas & equations (remember the diatomic elements!) b) balance the equations (if it won’t balance, you’ve written the formulas wrong!) 1. A clear solution of calcium chloride and a clear solution of sodium carbonate are mixed to form a white solid of calcium carbonate in a sodium chloride solution. 2. Solid potassium chlorate breaks down into a solid potassium chloride and oxygen gas. 3. Hydrogen gas and nitrogen gas are combined to produce ammonia (NH3) gas. 4. Zinc (s) + lead (II) nitrate (aq) yields zinc nitrate (aq) + lead (s) 5. Aqueous hydrochloric acid + aqueous magnesium hydroxide yields aqueous magnesium chloride and liquid water. 6. Aluminum bromide (aq) + chlorine (g) yield aluminum chloride (aq) + bromine (g) Type of Chem. RXN? Will this reaction occur? (need reference sheet) Predicting the Products of a Chemical Reaction Type of reaction 1. Predict the Products & Balance the Equation (show work below equation) __Al(s) + 2. __Mg(s) + Will it occur & Why? __Cl2(g)  __O2(g)  3. __Ca(NO3)2 (aq) + 4. __Na(s) + 5. __HCl(aq) + 6. __AgNO3(aq) + 7. __C6H6(l) + __O2(g)  8. __C3H8(g) + __O2(g)  9. __HgO(s)  10. __ H2O (l) + electricity __Ag(s)  __H2O(l)  __Ba(OH)2(aq)  __Na2CO3(aq)  LAB Data Table: Reactants 1. Mg (s) + Cu(NO3)2 (aq)  2. Cu (s) + CaCl2  3. Na2CO3 (aq) + CaCl2 (aq)  4. Zn(NO3)2 (aq) + Cu(NO3)2 (aq) Products Should it occur? Did you observe a reaction? What indicators did you see?
