What is a calorie? correct answersA unit of heat energy With our crude calorimeters in class we burned food by lighting it on fire. What chemical reaction occurs when food is burned? How does this reaction relate to the breakdown of food for energy in our body? correct answersA combustion reaction occurs. The food and oxygen in the air combine to form carbon dioxide and water molecules and produce lots of energy. This happens in the body as well, using enzymes to catalyze all of the reactions...

UNIT 4 Combustion of Methane: CH4(g) + 2 02 -> C02 (g) + 2 H20 (g) a) If we have five molecules of CH4 and eight molecules of 02, which is the limiting reactant? 02 is limiting reactant because it yields the least amount of product UNIT 4 N2 (g) + 3 H2 (g) -> 2 NH3 (g) Find mol of NH3 (reactant and excess) H2 is the limiting reactant because it yields 2 molecules of NH3 while N2 yields 6 molecules of NH3 UNIT 4 How many moles of Si3N4 can be made from 1.20 moles of of Si and...

spontaneous - ANSWER-a process that proceeds without continuous outside intervention nonspontaneous - ANSWER-a process that cannot occur on its own a process that requires continuous outside intervention to proceed If a process is spontaneous in one direction: - ANSWER-it must be nonspontaneous in the opposite direction Do spontaneous reactions start by themselves? - ANSWER-NO - require a little energy boost (ex: spark or external flame that ignites the flame in a gas lamp or gasolin...
