Recall from earlier that we drew graphs for the energy changes in exothermic and endothermic reactions. We can now add some information to these graphs. This will also explain why we draw these graphs with a curve rather than using a straight line from the reactants energy to the products energy.
The term National Guard was not the official name until 1933. While National Guard was used by some states before this time, individual state militia had various titles ranging from Mississippiâs State Guard to Indiana Legion. After World War II, the Air National Guard was created as a component of the newly established United States Airforce. Today, approximately 350,000 men and women serve in the National Guard and the Air National Guard, 39% of the Armyâs operational force. There are over 1,500 national days. Donât miss a single one.
