The modern model of the atom describes electrons in a little less specific detail than earlier models did. Why is it that being less sure about the placement of electrons in an atom is actually an improvement over earlier models?

The standard free energy of activation of a reaction A is Reaction B is ten million times faster than reaction A at the same temperature. The products of each reaction are 10.0 kJ mol-1 (2.39 kcal mol-1) more stable than the reactants.

How does the shape of a structure affect its overall strength

Kim is doing an experiment with sound waves. She tested to see how quickly a sound wave could travel through three different materials: a metal pole, a helium balloon and a glass of water. She recorded her results.
