Question

F. Combustion Reactions 1. liquid ethanol (C2H5OH) + oxygen gas A carbon dioxide gas + steam 2. gaseous propane (C3H8) + oxygen gas A carbon dioxide gas + steam G. Mystery Reaction For the mystery reaction, see if you can predict the products and balance the reaction Note that turmeric acted as an indicator, so it is not represented in the chemical reaction. Also the isopropyl alcohol did not react (it merely dissolved the substances). One of the products was a gas (which one?), and one was water. Can you identify the other products? calcium chloride(aq) + NaNCO3(aq) right arrow ??

Explanation / Answer

F. Completed balanced equations

a. C2H5OH(l) + 3O2(g) ----> 2CO2(g) + 3H2O(l)

b. C3H8(g) + 5O2(g) ---> 3CO2(g) + 4H2O(l)

G. the completed reaction with products formed,

CaCl2(aq) + 2NaHCO3(aq) ----> CaCO3 + CO2 + H2O + 2NaCl
