what is a reversible change?
478465
It is any change that will revert back to the original state, either automatically over time, or with the application of energy and organization.

lol chem... anyway a physical change is one that only effects apperence such as a paper ripping or adding paint to a wall. a chemical change changes what something is compleatly like burning paper changes it into ash

There is an entire branch of mathematics dealing with change, called calculus. \n\nThere are many math problems dealing with how you can make change from a certain amount of currency. \n\nBut I have never heard of anything called the Law of Change.

Physical\n\nA chemical change is a change in molecular composition. For example: When you mix baking soda and vinegar, it ceases to be simply soda and vinegar. A chemical reaction takes place.\n\nA physical change is a change in physical property. For example: The irons heating element is activated, causing the metal to warm up. It doesn't change to any other form of metal, nor does its structure differ afterwards. It mearly changes in physical temperature.

The quality of being changeable; mutability\n\nA sudden or unexpected change or shift.

any change from one state (gas, liquid, solid) which is accompanied by alteration of the chemical composition; any process in which one or more substances are changed into one or more different substances

This is a purely physical change of state from solid to liquid as a result of energy being added to the system.  There is an increase in entropy of the system.

Reverse engineering (RE) is the process of taking something (a mechanical device, an electrical component, a software program, etc.) apart and analyzing its workings in detail, usually with the intention to construct a new device or program that does the same thing without actually copying anything from the original. The verb form is to reverse-engineer, spelled with a hyphen.\n\norward engineering - The traditional process of moving from high-level abstractions and logical, implementation-independent designs to the physical implementation of a system.

A solute cannot undergo reversible oxidation/reduction if it diffuses away from the electrode. The diffusion coefficient simply measures how quickly this diffusion happens. \n\nWhen deciding how reversible a particular redox reaction is by CV, you have to consider both the intrinsic reactive properties of the species in solution as well as how much material is lost to analysis as it diffuses away from your electrode.

The activation energy of a reaction is different for every reaction and is totaly independant of wether the reaction is exothermic or endothermic. For any reaction to proceed the minimum energy must be equal to or higher than the activation energy.\n\nNow where your question can come in is, i think, is if the reaction is reversible. In one direction the reaction will be exothermic and in the opposite direction the reaction will be endothermic. For both the forward and backward reactions the activation energy is the same and there is nothing that can be done to change that.

not technically in the way we know it. According to Einstein time as the measure of distance in the figurative Universe can be turned back by exceeding a speed of the speed of light squared times the mass of the components at this speed. Read steven Hawking a history of time to learn further on the subject. Time in terms of the chemical equation, namely reactants to products can be reversed by this step. However, in respect to redoing certain moments in life, no. The only force which can do that is God.

A reverse exchange is when you close your replacement property before your relinquished property. \n\nThe advantage is that you're able to secure the property before your sale closes. This minimizes the risk of failing to identify replacement property within 45 days.\n\nThe downside is that reverse exchanges are much more expensive than a normal delayed exchange. On average reverses run between $6,000 & $10,000, as compared to our $500 fee for a delayed exchange.\n\nIf you have the ability to sell your property first then close on the purchase that will certainly save you alot of money, however if there's a large gain involved it may make sense for you to do a reverse. The best thing to do from here is consult with your CPA to find out what is your best option. \n\nIf you have further questions you're welcome to email me at alex@havenexchange.com or call toll free (866)794-1031, and I'll be happy to help.\n\nSincerely,\n\nAlex Goldsmith - Account Manager\nHaven Exchange

to what are you changing?

its not much different. and people like change, so they changed it.

The other name for a chemical change is a permanent change.This is because once a chemical change has taken place we cannot obtain the reactants back from the products formed during this change.\nexample=burning of wood to produce ash.We cannot get back the original wood from the ash that has been formed during this change.
