A suspension
mustard is heterogeneous because the mixture is distributed unevenly. which means that you can see the different particles in mustard.
It is a heterogenous mixture.
Oil is a heterogeneous mixture. This is because the components of the mixture are not evenly distributed throughout the mixture.
nothing, the particles are visible because the particles are in the mixture. The substances being visble and identifiable in a mixture is because that mixture is heterogenous.
No, it is a heterogenous mixture containg a liquid in which visible particles settle.
Heterogenous mixtures are not uniform throughout the liquid. For example flour and water mixture is heterogenous because the flour isn't going to be uniformly located throughout the liquid. Homogenized milk is homogenous, as the concentration of particles throughout the liquid is evenly distributed. Heterogenous mixtues will often "settle", homogenous will not settle over time.
In a homogeneous mixture the particles (atoms, molecules, or ions) of the substances mixed are distributed evenly so that any two samples taken from different locations in the mixture are identical. Examples include salt water, where the salt is evely distributed through the water, and brass, where the copper and zinc are evenly distributed. In a heterogeneous mixture the distribution is uneven and the components form two or more phases, in which the composition is different. For example, the two phases in mud are the water and the particles of dirt.
A syrup is heterogeneous.
Visible particles would be heterogeneous elements of a mixture. A truly homogeneous mixture would have no visible particles. However, you could still have an approximately homogeneous mixture with visible particles, evenly distributed throughout the mixture.
CO2 or dry ice
Soil would be a heterogenous mixture. A heterogenous mixture is not uniform throught out. A homogeneous mixture is the same throught out
No, they are in heterogenous form mixed: not as atoms or molecules but only as particles they mix, you can easily separate them by physical methods: a magnet will pick out the iron particles.
