Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
What is a hectogeneous chemical?
a hectogeneous chemical is a chemical in which vaporization,condensation,sublimation,and deposition form into one giant substance that turns into a chemical.
Explain why sublimation is regarded as a physical change but the slaking of lime is considered as a chemical change?
- Sublimation don't change the molecule; solid iodine or sublimated iodine are iodine. - Slaking of lime transform the calcium oxide in calcium hydroxide. A chemical change occur.
How can the efficiency of a chemical reaction be expressed?
A chemical reaction is represented by a chemical equation.
The chemical equation of iodine solid to gas?
The chemical equation for the sublimation of iodine solid to iodine gas is: I2(s) -> I2(g). This represents the process in which solid iodine directly transforms into iodine gas without going through a liquid phase.
What is the chemical equation for the sublimation of iodine?
heat in closed system with a cold finder on top to collect crystals. p.s. i hope you're not using red phos. too...
Is sublimation of sodium chloride chemical or physical change?
Sublimation is a physical change.
Is sublimation a chemical or physical?
Physical
Is iodine sublimating a chemical change?
Yes, the sublimation of iodine is a physical change, not a chemical change. Sublimation is the process by which a substance transitions from a solid directly to a gas without passing through the liquid phase. The chemical composition of iodine remains the same during sublimation.
Write the equation for the sublimation of ammonium chloride?
mesured mass-mass by subtraction/mass by subtraction * 100%
The phase change represented by the equation I2s to I2g is called?
The phase change represented by the equation I2s to I2g is called sublimation. This process occurs when a solid directly turns into a gas without passing through the liquid phase.
Is burning woo sublimation?
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
What are the chemical reactions involves in sublimation?
Sublimation, per se, does not involve any chemical reactions. It is simply a physical change of a substance going from a solid to a gas without passing through the liquid phase.
Why is the sublimation of dry ice and the expansion of gases not chemical reations?
A chemical reaction is one that changes the chemical properties of a substance. Sublimation is just going from solid to a gas and is only a change of state.
A shorthand description of a chemical reaction using chemical formulas and symbols is a chemical what?
A chemical equation is a shorthand description of a chemical reaction.
Why are sublimation and deposition are classified as physical changes?
Because sublimation and deposition doesn't change the chemical nature of the molecule.
