In chemistry, a chemical reaction is a process that leads to the transformation of one set of chemical substances to another. Both reactants and products are involved in the chemical reactions.
In chemistry, energy is what is required to bring about a chemical reaction. The total energy of a system is the sum of the potential energy of its constituent particles and the kinetic energy of these particles. Chemical energy, also called bond energy, is the potential energy stored in the chemical bonds of a substance. Chemical energy is released when a bond is broken during chemical reactions.

here's sort of a strange problem. Um, we're going to consider walking up the Empire State Building stairs and we're going to calculate the estimated we're going to estimate the potential energy expended. Okay, so we're gonna make some assumptions here. We're going to make the assumption that we're using em mass times G. That's 9.8 meters per second squared times the height. And that's gonna be the height of the Empire State Building. Okay, so and these are estimates, So we're gonna take our mass as 80 kilograms. Um, RG is a constant. That's 9.8 meters per second squared. And we're gonna take HH, which I just looked up as 3 81 meters. So plugging these values into our equation, we get u equals 80 kilograms times 9.8. Having trouble, really? My eighths meters per second squared times 381 meters. Do the answer for this and I get 298 1000 700 some odd kilogram meters squared per second squared, which is Jules. So I've got you equals 200 98,700 jewels. And let's just round that three sig figs that will go 290 nine Kila jewels And again, these are just some estimates, so you could use different numbers and get different values.
