Ques:Answer the following question given this paragraph: A: The energy is stored in the bonds of the products as chemical energy. In an endothermic reaction, the products have more stored chemical energy than the reactants. This is represented by the graph on the left in the Figure below . In an exothermic reaction, the opposite is true. The products have less stored chemical energy than the reactants. You can see this in the graph on the right in the Figure below . Q: Endothermic and exothermic reactions differ in whether the products or reactants store more of what? Choices: - Motion energy - Thermal energy - Kinetic Energy - chemical energy A:

Ans:chemical energy

Ques:Answer the following question given this paragraph: Both of these people are participating in a board sport, but the man on the left is snowboarding in Norway while the woman on the right is sandboarding in Dubai. Snow and sand are both kinds of matter, but they have different properties. What are some ways snow and sand differ? One difference is the temperature at which they melt. Snow melts at 0C, whereas sand melts at about 1600C! The temperature at which something melts is its melting point. Melting point is just one of many physical properties of matter. Q: The temperature at which something melts is refered to as what? Choices: - precipitation point - evaporation point - boiling point - melting point A:

Ans:
melting point
