Burning Money Experiment
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...
Returning to the classroom
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...
Catalyst and Activation Energy
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
Entropy – Microstate and Macrostate
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...
Bond Energy and Bond Enthalpy
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...
Reaction enthalpies
Enthalpy change For a reaction Bonds Know that Breaking bonds always requires energy (never releases energy) Forming bonds always releases energy (never requires energy) Exothermic and endothermic process Breaking bonds is always an endothermic process (whether...
Reaction Coordinate Diagram
Given the following reaction, sketch a reaction coordinate graph. The reaction involves two steps, step 1 is the slowest step and step 2 is the fastest step. Indicate on the diagram the overall enthalpy change of the reaction, the reaction for the transitions states and intermediate states.
H2(g) + 2ICl(g) –> 2HCl(g) + I2(g)
Memorizing the Names of Polyatomic Ions
Examples of polyatomic ions Generally, polyatomic ions have suffixes that end in "ite" or "ate" if they contain oxygen atoms. chloridehypochloritechloritechlorateperchlorate Note: Chloride shown above is not a polyatomic ion, it's a monoatomic ion...
Compounds with Polyatomic Ions
What are polyatomic ions? Ions are formed when neutral atoms gain or lose electrons. Similarly, a polyatomic ion is formed when a neutral molecule gains or loses electrons. A polyatomic ion is a charged group of atoms covalently bonded together. Majority of the...
