A solution is considered homogeneous when its components are uniformly distributed and have the same physical and chemical properties throughout. This results in a single phase with no visible boundaries between the different substances dissolved in the solvent.
No, in a physical change, no new substances are formed. The change only affects the physical appearance or state of the matter, such as size, shape, or phase, but the chemical composition remains the same.
Heterogeneous physical refers to a system where the components or substances within it are not uniform or of the same kind. This means that there are different types of materials or substances present within the system, displaying varying physical properties or characteristics.
- chemical analysis of these substances - determination of some physical properties
During a physical change, the composition of the materials remains the same. The change only affects the physical properties of the substance, such as its shape, size, or state of matter, without altering its chemical composition. This means that no new substances are formed during a physical change.
When ammonium chloride(NH4Cl) is dissolved in water the solvation process itself is a physical change, NH4Cl changes from one of its state (crystalline) to solution, where NH4+ and Cl- ions are surrounded by water molecules.
A physical change has occurred, where the ammonium chloride solid has dissolved in water to form a colorless solution. No new substances are formed in this process, so it is still the same compound but now in a different state (solid to solution).
Urine is a liquid waste product composed of water, electrolytes, and waste substances like urea and creatinine. It is not a compound but a complex mixture.
in both, substances mix together
in both, substances mix together
A solution is considered homogeneous when its components are uniformly distributed and have the same physical and chemical properties throughout. This results in a single phase with no visible boundaries between the different substances dissolved in the solvent.
Isotonic solution
Not necessarily. Some chemical reactions may change the physical state of matter (e.g. solid to liquid), while others may not involve a change in physical state. It depends on the specific reaction and the properties of the substances involved.
No, in a physical change, no new substances are formed. The change only affects the physical appearance or state of the matter, such as size, shape, or phase, but the chemical composition remains the same.
No. The cheese is still cheese, it's just in pieces now.
Mixtures and solutions are both combinations of two or more substances. In a mixture, the substances are physically combined and can be separated by physical means, while in a solution, one substance (solute) is dissolved in another (solvent) at a molecular level and cannot be easily separated.
Yes, in a physical change, the arrangement or state of the particles in a substance can change, but the chemical composition and fundamental properties remain the same. Examples of physical changes include changes in state (solid to liquid), size, shape, or phase transitions.
