Okay so similar to Benny, this is what I had for my assessment!
Which form of energy changes in chemical reactions due to bonds breaking and forming?
- potential
What does it mean for a reaction to release energy?
- The relative potential energy of the reaction is positive.
Carbon monoxide and nitrogen monoxide react to produce carbon dioxide and nitrogen gas. If the system contains platinum, then less energy is required for the reaction to occur. Which term best describes the role of platinum in the system?
- catalyst
The two oxygen atoms in a molecule of oxygen gas share their outer electrons. Which type of bond do the oxygen atoms form?
- covalent
A scientist fills two test tubes with different aqueous solutions and adds different compounds to each solution. After the reactions are complete, the scientist measures the temperature of each solution. The table shows the results of the experiment.
Test Tube 1 Test Tube 2
Initial Temperature 20°C 20°C
Final Temperature 25°C 19°C
Which statement best explains the results?
- The reaction in test tube 1 is exothermic, and the reaction in test tube 2 is not.
