BALANCING CHEMICAL EQUATIONS – PG. 30

RULES FOR BALANCING CHEMICAL EQUATIONS 1. Draw a chart underneath the yield sign 2. Count all elements and list them in both columns Al + O 2 Al 2 O 2 3. Pick an element that is not equal on both sides and find the least common multiple 4. Add coefficients to the chosen element and recount atoms 5. Repeat steps 3 - 4 for unbalanced atoms until all elements are equal 6. Write the balanced equation for full credit

COMBUSTION OF ISOPROPYL ALCOHOL

COMBUSTION OF ISOPROPYL ALCOHOL BALANCE THE FOLLOWING CHEMICAL REACTION 10. Balance the following chemical reaction using steps 1 -6 in your notebook. You must show your steps. _____ Na 2 O 2 + _____ H 2 O _____ Na. OH + _____ O 2

DISCUSSION QUESTIONS: 1. CAN YOU TELL WHETHER ENERGY WAS ABSORBED OR RELEASED IN THIS REACTION? EXPLAIN HOW YOU KNOW… 2. DOES THAT MAKE THIS REACTION ENDOTHERMIC OR EXOTHERMIC? EXPLAIN… 3. WHICH SIDE WOULD ENERGY BE FOUND ON? Energy is released with this reaction: We call this EXOTHERMIC for “EXIT HEAT” 2 C 3 H 8 O + 9 O 2 6 CO 2 + 8 H 2 O+ energy

INTRODUCTION TO ENERGY RESOURCES 1. Read the article: “Do We Grow It or Mine It? ” 2. As a group, Go back through the article and complete the comparing and contrasting energy resources worksheet. 3. Review and discuss answers as a group. 4. Review as a class.
