Sand and chalk are not a homogeneous mixture because they do not have a uniform composition, meaning their components are visibly distinguishable from each other. Sand consists of larger particles like silica, while chalk is composed of calcium carbonate.
Beach sand is a heterogeneous mixture
No, if sand is included its heterogeneous.
no, a homogeneous mixture is salt water, seawater has other particles in it like sand, bacteria, and other debris that can be seen making it heterogeneous
It is heterogeneous mixture because it is not mixed in equally.
When chalk is dissolved, the solid particles of chalk break down and disperse into the liquid it is dissolved in. This results in a homogeneous mixture where the chalk particles are spread out evenly throughout the liquid.
This mixture is not homogeneous.
No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
Salt and sand is a mixture.
Beach sand is a heterogeneous mixture
Sand and pebbles is a heterogeneous mixture. A solution is a homogeneous mixture.
Sand and pebbles is a heterogeneous mixture. A solution is a homogeneous mixture.

Finally divided sand may be homogeneous.
YES! Sand is a mixture. Sand is classified as a heterogeneous mixture because it does not have the same properties, composition, and appearance throughout the mixture. A homogeneous mixture has a uniform mix throughout.
No, if sand is included its heterogeneous.
Chalk is a heterogeneous substance because it is composed of various materials such as calcium carbonate, quartz, clay, and other minerals. These materials are not uniformly distributed throughout the chalk, resulting in a non-uniform composition.
