in their natural state, Na and Cl are neutral, unstable. When reacting, Na will lose an electron to Cl, and the resulting Na+ is eletrostatically attracted to Cl-. In the end, two neutral unstable compounds form a single polar, stable compound that is neither reactive like sodium or toxic like chlorine
I think it is a chemical change Forming underground it is a chemical change Salt forming from a saline solution for example h20 + NaCl --delta-> h2 + O2 + NaCl (This is not a balanced solution) This is a physical change, since there is no change to the Sodium Chloride
It is chemical. It is chemical because when salt is formed from elements it becomes a chemical and not a physical.
When salt is mixed in with water, they form a solution. Salt is the solute, and water is the solvent.
Mixing an acid and base to produce water and a salt is a chemical change because new substances with different chemical properties are formed. The reaction between the acid and base involves the breaking and forming of chemical bonds, resulting in the formation of water and a salt.
It is a physical change because the chemical composition of salt and water do not change. You can separate the salt and water physically by allowing the water to evaporate, which leaves the salt.
Mixing Epsom salt and ammonia would result in a physical change. It is considered physical because no new substances are formed during the mixing process.
This is a physical process, but sodium and chloride ions ar formed.
This is a physical process, but sodium and chloride ions ar formed.
The dissolving of salt in water is considered a physical change, not a chemical change. This is because no new substances are being formed during the process; the salt molecules are simply breaking apart and dispersing throughout the water.
Mixing salt and pepper is a physical change
Dissolving table salt in water represents a physical change, not a chemical change. The salt molecules remain intact and simply disperse in the water, without any chemical bonds being broken or formed.
Physical change as no new substance is formed and the properties have also not changed. Hope it helps!
