Is brass a mixture in which the particles are evenly mixed at the level of atoms or molecules?
Brass is an alloy, which is (generally) a combination of metals in a metallic matrix. In the case of brass, we see copper and zinc in combination, and these metals come together to become evenly mixed at the atomic level. That said, is brass a mixture in which the particles are evenly mixed at the level of atoms or molecules? Yes, it is.

Why does a liquid rise in a capillary tube?
This is due to Surface Tension. The molecules/atoms of the liquid are atrracted by the particles of the solid and thus the liquid rises in the capilliary tube.
Is rubber water resistant?
Rubber and most plastics are made primarily from chains of carbon atoms bonded together. Typically two hydrogen atoms are attached to each carbon atom. The bond between the carbon atoms and hydrogen atoms is created by sharing electrons. In the case of carbon and hydrogen, they share electrons evenly, and each carbon atom likes to make 4 bonds, which distributes the hydrogen atoms and the electron around the carbon atoms evenly. The end result is that most rubbers and polymers are not polar. Water is an oxygen atom bonded to two hydrogen atoms. Oxygen likes to bond to two other atoms. The two atoms are not dispersed evenly around the oxygen, hence one side of the oxygen is exposed. Oxygen has more electrons that carbon and is more negatively charged. So an water molecule tends to have a positive end and a negative end (the two hyrdrogens are mostly on one side). Hence water is a very polar molecule. There is a saying that "like disolves like". The positive end(s) of a water molecule are attracted to the negative ends of a water molecule. This is called hydrogen bonding. Hence water molecules are attracted to each other, which is why water is a liquid instead of a vapor. Water molecules are small, and without this hydrogen bonding they wouldn't stick together. The would fly off into the atmosphere. An anology is that each water molecule is like a magnet. If you stick a large number of magnets together they will stick to each other. Since rubber and polymers (plastics) are not usually polar and hence have no significant positive or negative ends or parts, there are no positive or negative charges for water to stick to. Hence they do not typically mix. This description is a broad generalization. Different polymers have different degrees of polarity and varying affinity for water. However rubber is very non-polar so this description is accurate.
What are the components of brass?
Brass is an ALLOY , a mixture of the metallic elements of copper and zinc. They do NOT chemically combine. A compound involves the exchange of electrons between the reacting atoms. A mixture(alloy) doe NOT involve this exchange of electrons.
What did vulcanization do?
vulcanisation- when sulfur atoms form cross-links between rubber molecules. vulcanised rubber is used to make car tyres and conveyor belts. :)
What is space lattice?
Space lattice is a three-dimensional geometric arrangement of the atoms or molecules or ions composing a crystal. Space lattice is also known as crystal lattice or Bravais lattice.
What is homogeneous mixture with evenly distributed atoms or molecules?
solution
How are the particles of the solution like?
In a solution, the particles are evenly distributed throughout the solvent. These particles can be molecules, ions, or atoms that are in a homogeneous mixture with the solvent. The size of the particles in a solution is typically smaller than those in a suspension or colloid.
A temporary mixture the particles will eventually settle?
When all of a mixture's atoms, molecules, and particles are evenly mixed it is called a colloid.
Are particles in molecules?
Yes. Molecules are composed of atoms. Atoms are composed of particles.
What are molecules and their subatomic particles?
Molecules contain atoms and these atoms contain subatomic particles.
Which particles in an atom are in the molecules?
All of them. Molecules are made of atoms, not pieces of atoms.
What tiny particles make up molecules?
Atoms are the tiny particles that make up molecules. Atoms are composed of protons, neutrons, and electrons. Molecules are formed when atoms combine together through chemical bonds.
What is the difference between a homogenous and heterogenous mixture?
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.
Are molecules and particles the same in terms of their composition and structure?
No, molecules are made up of atoms bonded together, while particles can refer to atoms, ions, or molecules. So molecules are a type of particle, but not all particles are molecules.
What are not subatomic particles?
Atoms, molecules, and cells are not subatomic particles. Atoms are made up of subatomic particles (protons, neutrons, electrons), molecules are made up of atoms, and cells are the basic unit of life in living organisms.
What is the scientific name of particles which make up particles?
atoms and molecules
How can we determine that water is a compound not a mixture?
Water is a compound because its molecules are formed of chemically combined elements (hydrogen and oxygen) in a fixed proportion. A mixture is a combination of separate atoms, molecules, or particles that are not chemically bonded or in any fixed proportion.
