The chemical energy in the reactions is almost equal to the chemical energy in the products
Normally in cooking cut apples are sprinkled with lemon or lime to slow oxidation (browning). Vinegar will also work depending on what you need the apples for.
Lemon Juice (i tried)
Petroleum Jelly on the cut edges of a pumpkin will slow the oxidation and rotting of the fruit.
The evaporation of water is slow when water is dissolved in salt. This is because of the salt molecules, the salt molecules is the reason for the slow evaporation.
Salt cannot bring a fly back to life, it kills slugs because salt absorbs the water and dries them up. Salt cannot bring a fly back to life. It can revive it from a sleep which naturally occurs when the fly is faced with overwhelming pain though. Salt has certain properties which makes it draw moisture from things around it. As a slug has a very high percentage of water in its body, it is easy for salt to draw the water from the slug, causing its osmolarity rate to slow and it will become severly dehydrated and shrivel up, a waterless shell.
maybe. Rotting of wood is a slow chemical process. Trying to cut up a tree with a small knife is slow, but that would be a physical change.
Salt will slow freezing, but not evaporation. As say salt water evaporates, it will leave behind its salt contents, but it will not evaporate any slower than fresh water.
No, the capsules are a slow-release formulation and should not be crushed, chewed or opened per the manufacturer.
Salt (sodium chloride, NaCl) is quickly dissolved in water.
Yes, salt lowers the freezing point of ice.
you can prevent an apple from browning by adding lemon juice to it
