Answer the following questions showing all appropriate work.


1) After balancing the chemical reaction below, determine how many gram of C12H22O11 (called sucrose) you need to make 61.3L of carbon dioxide (@STP)?

 ____ C12H22O11(s)  + ____ O2(g)   ---> ____ C1O2(g)  + ____ H2O1(g)


2) Using your knowledge of single replacement reaction, determine the Balanced complete chemical reaction for the reactant below including phases. Then determine how many grams there are of one of the products if you react 94.7g of the zinc acetate. (Assume reaction occurs even if it does not)

 ___ Al(s)  +  ___ Zn1(C2H3O2)2 (aq)  -->


3) Using the answer to the question above (Question 2), determine the number of base particles of the other product (one you did not answer from the Question 2).


4) After balancing the chemical reaction below, determine how many grams of dihydrogen monoxide you make if you react 79.1g of nitrogen monoxide (assuming there is sufficient amount of other reactants).

 ___ NH3(g)  + ___ NO(g) --> ___ N2(g)  + ___ H2O(g)








Answers
1) 78.0g C12H22O11
If 2) 33.6g Zn then 3) 2.10E23 f.u. Al1(C2H3O2)3
If 2) 70.4g Al1(C2H3O2)3 then 3) 3.12E23 atoms Zn
4) 47.5g H2O1
