Answer:
Explanation:
The second best answer is its group on the periodic table.
That answer depends on the actual reason. The number of protons determines which element you are talking about.
Answer:
1. Metal.
2. Atom.
3. Homogeneous
4. Compounds.
5. Lustrous
6. Saturated.
7. Colloidal; true.
8. Homogeneous.
Explanation:
1. An element which are sonorous are called metal.
2. An element is made up of only one kind of atom.
3. Alloys are homogeneous mixtures.
4. Elements chemically combines in fixed proportion to form compounds.
5. Metals are lustrous and can be polished.
6. A solution in which no more solute can be dissolved is called a saturated solution.
7. Milk is a colloidal solution but vinegar is a true solution.
8. A solution is a homogeneous mixture.
Answer: An initial velocity
Explanation:
Answer:
Separation by density
Explanation:
Mixtures are made up of two or more pure substances which tends to keep their individual identities. These components can be separated from each other by different physical techniques.
Mixtures are further classified as;
(i) Homogenous Mixture:
In this type of the mixtures the components are uniformly mixed and their properties as well as composition as uniform throughout. Such mixtures are also called as solutions.
The physical methods used to separate these components from each other are distillation (taking heat and pressure into account), Solvent extraction, Magnetic separation, Chromatography e.t.c.
(ii) Homogenous Mixture:
In this type of the mixtures the components are not uniformly mixed and their physical properties and composition are also not uniform.
The physical methods used to separate these components from each other are Filtration, Magnetic Separation, Centrifugation, Flotation e.t.c.
So, in given options the density can play role by settling the massive components of heterogenous mixture to sit at the bottom and separated
