Answer to: Determine the energy change for the following reaction. Indicate if it is endothermic or exothermic. H_2 + Cl_2 \rightarrow 2HCl By...
Energy assumes several forms; it may be thermal (in the form of heat), electrical, mechanical, chemical, radiant, or kinetic. In doing work, the energy is changed from one form to one or more other form(s). In these changes some of the energy is “lost” in the sense that it ...

Back to a chemical reaction: when you change the temperature, the equilibrium point also changes. Instead of changing the spring constant, we change the equilibrium constant, which manifests as a change in the reference force, ΔG°. For a certain Q - at a lower temperature the driving forc...
Home energy management and control changes with the seasons. There are different steps you can take as the temperature fluxuates in order to keep your energy bills down and your home comfortable. Winter Cold If you're willing to be active in managing your home's energy resources, there are...
In chemistry, energy changes arise due to two key processes: the formation of a chemical bond and the breaking of a chemical bond, where the term "chemical bond" refers to any of the following: ionic bond, covalent bond, metallic bond and intermolecular force of attraction (although some may...
How would changes in substrate concentration change the reaction rate of enzymes? What is the activation energy of a chemical reaction, and how does an enzyme allow this obstacle to be overcome much more easily? How do enzymes affect reactions?
However, while fossil fuel technologies, nuclear fission reactors, and (under certain conditions) hydroelectric power can have their energy outputs tweaked to meet real-time changes in demand, many types of renewable or even future energy solutions simply aren’t as reliable or controllable in real...
vary in how much a system’s environment can be a part of the changes it’s undergoing until the system is no longer considered “self-organized.” Since you asked about ‘The Big Bang,’ it’s important to point out that it is still a theory (widely accepted, but a theory nonetheless...
