What else can I help you with?
What is it when two or more substances mix together so well that they appear to be a single substance?
Homogeneous mixture.
What is the shininess or dullness of a substance called?
The shininess or dullness of a substance is called its luster. It refers to the way light is reflected off the surface of the material. Substances with high luster appear shiny, while those with low luster appear dull.
What happens molecularly when a substance goes through a phases to get from a solid to a gas?
The particle theory states that all particles are made of matter, these particles are in constant motion and there is a force of attraction between these particles. Solids have more closely packed particles and thse particles get looser as they progress through the states from liquid to gas. Therefore, moleculary, the molecules move faster and faster and appear farther and farther away from each other.
What do particles look like in a syringe?
Particles in a syringe may appear as a suspension or solution depending on the type of material being injected. Suspensions typically look cloudy or have visible particles floating in the liquid, while solutions are usually clear and homogeneous. Observing particles in a syringe can give clues about the nature and consistency of the substance being dispensed.
What color is a substance?
The color of a substance depends on how it interacts with light. Substances can appear different colors based on the specific wavelengths of light they absorb and reflect. For example, a substance that absorbs all wavelengths of light appears black, while a substance that reflects all wavelengths appears white.
When substances in a mixture appear to be a single substance like salt water?
homogeneous mixture
What is it when two or more substances mix together so well that they appear to be a single substance?
Homogeneous mixture.
Do particles get smaller or bigger when heated?
When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
What happens when under decolourised?
When decolorized, a substance loses its color through a process that typically involves removing impurities or altering the structure of the molecules responsible for the color. Decolorized substances may appear transparent, white, or colorless.
Why does a solution look like a pure substance?
I think what you meant to ask is why does a solution look homogenous, and it is solely because a solution IS homogenous. A homogenous mix, is a mix between 2 or more substances where the mix appears as only one substance Opposingly, a heterogenous mixture is a mix of 2 or more substances where all of the substances can be identified by the human naked eye.
What is the shininess or dullness of a substance called?
The shininess or dullness of a substance is called its luster. It refers to the way light is reflected off the surface of the material. Substances with high luster appear shiny, while those with low luster appear dull.
Why are solutions mistaken for a pure substances?
Solutions are mistaken for pure substances because they often appear uniform and have consistent properties throughout the mixture. However, solutions are actually a homogeneous mixture of two or more substances, where one substance (solute) is dissolved in another (solvent). This is different from a pure substance, which consists of only one type of particle.
What are similarities between mixtures and solutions?
A suspension is where the particles of the solute aren't spread evenly throughout the solvent while a colloid is where two or more substances are mixed together but appear to be only one substance.
Use the particle theory to explain the expansion and contraction of a solid when temperature is changed?
The expansion and contraction using particles is when a liquid melts because the particles get more energy and move around so making the substance appear less then there is and when the particles cool down they loose energy and move around slower so making them appear bigger than when they were warmer.
What does luster mean in chemistry?
In chemistry, luster refers to the way a substance reflects light. Substances with high luster appear shiny and reflective, while substances with low luster appear dull. Luster is often a characteristic used to describe the physical appearance of metals and minerals.
Why do dense white fumes appear?
Dense white fumes can appear due to the release of a substance that is reacting with the air or water vapor. Common sources include chemical reactions, combustion processes, or overheating of materials, resulting in the formation of solid particles that scatter light and appear as white fumes.
What happens molecularly when a substance goes through a phases to get from a solid to a gas?
The particle theory states that all particles are made of matter, these particles are in constant motion and there is a force of attraction between these particles.
