help with pre lab

low are several ways of slowing reactions in real-world situations. For each, identify the factorts) of the "Collision Theory of Chemical Reactions" that is used to slow the reaction rate. Explain 6. Listed be why your answer (or answers) is the correct one. dousing a fire with water a. b. dousing a grease fire with CO2 from a fire extinguisher ce using additives in food that tie up metal contaminants (metals make the food spoil faster) d. sealing food with plastic wrap (gases can't pass through the plastic wrap and react with the food to spoil it) e. refrigerating food to prevent spoilage

Explanation / Answer

a. dousing a fire with water: Fire reacts dynamically with water and gets extinguished.

b. dousing a grease fire with CO2 from a fire extinguisher: Grease fire reacts gently with CO2 and gets extinguished.

c. using additives in food that tie up metal contaminants (metals make the food spoil faster): metal gets oxidized due to the air in the food and the food gets spoiled.

d. sealing food with plastic wrap (gases can't pass through the plastic wrap and react with the food to spoil it): The gas present in the plastic wrap reacts with food and makes it spoil.

e. refrigerating food to prevent spoilage: The freons (chlorofluorocarbons) present in the refrigerator react with the food and protects it without spoiling.
