Burning money experiment for chemistry This discrepant event is short but can be made into a lot of fun with a little theater: Find the largest dollar bill amount in the classroom. I like to ask the class who the “big shot” is in the class and then proceed to ask them how much money […]
The 2020-2021 school year had its challenges, no doubt. Here are the top three things you should do to ensure a successful year for 2021-2022. Without further ado, let’s jump in! 1) Make your students excited to be back! Yes, this is the absolute best thing you can do for your students. Students learn drastically […]
Catalyst A catalyst is a substance that speeds up a chemical reaction but it does not undergo a chemical reaction itself. The catalyst allows the reaction an alternative pathway to take place. The catalyst does not lower the activation energy of the reaction. Analogy
The term microstate refers to the behavior of atoms and molecules in terms of how energy is redistributed among the particles in a system. A microstate is the arrangement of molecules within a macrostate, that is, within a system with very specific properties. If atoms have more energy and freedom of movement in a macrostate, […]
Bond Enthalpy Introduction In order to understand why breaking bonds requires energy (endothermic) and making bonds releases energy (exothermic), one must first understand the nature of a chemical bond and why it occurs in the first place. Remember that bonds are due to the exchange or sharing of electrons between atoms. Forming bonds is a […]
