if sodium chloride dissolves in water what is it a chemical or physical change?
The dissolution of sodium chloride in water is considered a physical change because no new substances are formed - the sodium chloride remains as sodium and chloride ions in the water solution.
Is adding calcium chloride to sodium carbonate a physical change or a chemical change?
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.
Why is sodium chloride a compound and not a mixture of sodium and chlorine?
Sodium chloride is a compound because it is formed by a chemical bond between sodium and chlorine atoms. In a compound, the elements are chemically bonded in fixed proportions, creating a new substance with different properties than its components. A mixture, on the other hand, is a physical combination of substances that can be separated by physical means. Sodium chloride cannot be separated back into its original elements by physical means.
Is iron chloride and sodium hydroxide a physical or chemical change?
The reaction between iron (III) chloride and sodium hydroxide is a chemical change as new substances are formed. Iron (III) hydroxide and sodium chloride are produced as a result of the reaction.
When sodium chloride is dissolved in water sodium cations and chloride anions are formed what kind of reation is taking place is what?
The dissolution of sodium chloride in water is a type of a physical process known as dissociation. The ionic bonds in the solid sodium chloride break apart in water, causing the sodium cations and chloride anions to separate and become surrounded by water molecules.
Is sodium chloride a chemical or physical property?
Sodium chloride is a chemical compound (NaCl), not a property.
What is sodium chloride apperence?
The physical appearance of Sodium chloride is a white crystalline solid.
if sodium chloride dissolves in water what is it a chemical or physical change?
The dissolution of sodium chloride in water is considered a physical change because no new substances are formed - the sodium chloride remains as sodium and chloride ions in the water solution.
Is dissolving sodium chloride a chemical or physical change?
Dissolving sodium chloride in water is a physical change because the chemical composition of sodium chloride remains the same. The sodium and chloride ions are simply dispersed throughout the water, but they can still be recovered by evaporating the water.
How is calcium chloride different from sodium chloride?
Sodium chloride is NaCl, calcium chloride is CaCl2. Consequently all the physical and chemical properties are different.
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
What is sodium chloride sodium sulfate?
Sodium chloride has the chemical formula NaCl and sodium sulfate has the chemical formula Na2SO4.
Is sodium chloride physical or chemical?
This is a chemical reaction, a chemical change.
Is melting sodium chloride a physical change?
Yes, melting sodium chloride is a physical change because it involves a change in state from a solid to a liquid without altering the chemical composition of the substance.
Is heating sodium chloride a chemical change?
No, heating sodium chloride is a physical change rather than a chemical change. When heated, sodium chloride simply changes physical state from a solid to a liquid (molten form) without any change in its chemical composition.
Is adding calcium chloride to sodium carbonate a physical change or a chemical change?
Adding calcium chloride to sodium carbonate would be a chemical change because it results in the formation of new substances (calcium carbonate and sodium chloride) with different chemical properties than the original reactants.
Is sulfur sodium chloride sand a physical or chemical?
sulfur sodium chloride sand is a homogeneous mixture (solution)
