Because, particle shape and size varies and the distribution of particles is unequal. no two samples could ever be the same. It is heterogeneous, not homogeneous.
Yes, salt and pepper together make a mixture. It is a heterogeneous mixture.
No, black pepper is not a pure substance. Instead, black pepper is what we call a mixture substance. However, salt is a pure substance.
Mixing salt and pepper results in a MIXTURE, not a new compound.
A mixture of salt and pepper can be separated entirely by using your hand. Since salt is much finer than pepper, you can easily use your fingers to pick out the larger pepper pieces while letting the salt pass through.
No, salt and pepper cannot make gunpowder. Gunpowder is a mixture of saltpeter (potassium nitrate), charcoal, and sulfur. These ingredients have specific properties that allow for combustion when ignited, which is different from the properties of salt and pepper.
Yes, salt and pepper together make a mixture. It is a heterogeneous mixture.
No. A mixture of salt and pepper is simply a mixture of salt and pepper. Silicon is an element unrelated to either salt or pepper.
No, black pepper is not a pure substance. Instead, black pepper is what we call a mixture substance. However, salt is a pure substance.
Yes, salt and pepper would be considered a heterogeneous mixture because you can see the individual components (salt and pepper) without a uniform distribution.
Mixing salt and pepper results in a MIXTURE, not a new compound.
If you mean salt & pepper in the same container, I would say heterogeneous mixture, but salt by itself would be a compount (NaCl?), while pepper would likely be a homogeneous mixture (milled black pepper).
Pepper will not dissolve in water.
Salt is soluble in water, unlike pepper, so you can put the mixture in water and filter it using a coffee filter. The pepper will stay in the coffee filter and the salt can be separated from the water by leaving the solution in the sun.
No, a mixture of pepper and water would not be considered a solution. In chemistry, a solution is a homogeneous mixture where one substance (the solute) is dissolved in another substance (the solvent). In this case, pepper does not dissolve in water, so it would not form a solution. Instead, it would be considered a suspension, where the pepper particles are suspended in the water but do not dissolve.
A mixture of salt and pepper can be separated entirely by using your hand. Since salt is much finer than pepper, you can easily use your fingers to pick out the larger pepper pieces while letting the salt pass through.
First put the mixture in a colander and separate the salt and pepper from the pebbles. Then put the salt and pepper in water and stir it to dissolve the salt. The pepper will not dissolve, and you can remove the pepper. Then allow the water to dissolve and you will be left with the salt.
Salt and pepper are considered a mixture, not a solution or a colloid. In this case, salt and pepper are mechanically mixed together, but the individual components do not dissolve into each other or form a stable suspension.
