Components of a mixture differ from the components of a pure substance?

The concentrations of the components of a mixture may vary. However, a pure substance has a definite composition that does not vary.

∙ 9y agoThis is not true. If elements merely mix together, they retain their own properties. However if they react together to form a compound the properties are very different from those of the constituent elements. The reason is that a compound is made of different particles than those in the elements.
A simple example is hydrogen and oxygen.
The elements are both invisible gases at room temperature. Hydrogen is explosive, and oxygen makes things burn. If you mix them you still have invisible gas, and the mixture is dangerously explosive. The particles are separate H2 and O2 molecules.
If you make a compound between them, water, you have a liquid at room temperature, which puts fires out. The particles are H2O molecules.
Remember, the numbers must be subscripts.

∙ 11y agoYes. For example, combining gases oxygen and hydrogen gives you water. Combining sodium and chlorine (both dangerous and toxic elements) gives you common salt.

A mixture contain two or more components.

∙ 10y agoWhen elements combine to form a MIXTURE, the resulting properties may be very different from those of the elements that make it.

Wiki User
∙ 10y agoThe ratio of elements in a compound (measured by the number of atoms) is an exact constant. In a mixture it can vary.

∙ 12y agoThis is true. Take table salt, for example. Salt is sodium chloride. Sodium and chlorine are both volatile chemichals on their own, but combined, form a nutrient required by the human body.

How can mixtures of the same substance differ?
Both mixtures and pure substances have measurable and observable chemical properties and physical properties. A liquid mixture vaporizes over a temperature range; whereas, a pure substance boils at a fixed temperature.
How can you tell just by looking whether a mixture in water is a solution or a suspension?
If the mixture is completely homogeneous, then the mixture is true solution as in thesolution the solute particles are completely dissolved and have uniform composition.These are transparent.A colloid is a type of mixture in which one substance is dispersed evenly throughout another. These are mostly translucent, for example:-milk.A suspension is most easy to identify since the solute particles do not dissolve in the solution. They either keep floating in the solution or settle down at the bottom.
What is the difference between set and kit?
A set is composed of similar components (set of similar gaskets or a set of hand tools for example), while the kit consists of parts which differ from each other (a kit required to assemble something for example).
How is adding a ammeter to a circuit different from adding a light bulb?
When you add a light bulb, you are adding a load, which performs a function - in this case, it converts electrical energy to light and heat energy. When you add an ammeter, most of the time you intend to measure the current in the circuit, which is the function of the ammeter. Thus the two electrical components differ in their function and does different things when added to a circuit.
How does the bulk flow of filtrate into the capsule differ from diffusion?
The bulk flow of filtrate is a type of diffusion. Diffusion is a broad category of distribution of a substance within another substance. Diffusion can be specific or general in location and rate of flow.
How does heterogeneous mixture differ from a pure substance?
A heterogeneous mixture contains multiple chemical substances combined in a non-uniform way, whereas a pure substance contains molecules with only one chemical identity. For example, salt is a pure substance, whereas a mixture of salt an rocks is a heterogeneous mixture.
How do mixtures affect characteristic properties of matter?
A homogeneous mixture is a type of mixture in which the composition is uniform and every part of the substance has the same properties, for instance mixture's physical properties, such as its melting point, may differ from those of its individual components.
What are two ways which mixture differ from compound?
The ingredients in a mixture are not in any fixed proportion to each other; they are in fixed proportions in a compound.The individual components in a mixture keep their own characteristics but the components of a compound have different characteristics than those of the individual parts.The components of a mixture are unchanged from their original states and can be separated by physically means. The components of a compound are chemically and physically altered from their original states and cannot be separated from the compound by physical means.A mixture is prepared by physical means and can be separated by physical means, while a compound is prepared chemically and may (generally) disitegrate chemically, although not necessarily to original componentsA compound has single boyling, freezing points while a mixture may havesome, or rangeWhich what?

How do these components of atom differ from each other?
There are three main components in an atom. Protons and electrons have +1 and -1 charges respectively. Neutrons carry no charge.
How does the composition of a pure compound differ from that of a mixture?
A compound consists of two or more elements that have physically reacted and bonded together, either ionically ar covalently. An example of this is water - H2O. A mixture, on the other hand, is two or more substance that have been brought together, but have not chemically bonded with each other.
What are two way in which mixture differ from compounds?
A mixture consists of multiple compounds rather than the compound which consists of different elements. A mixture can be separated more easily into its components and has weak and strong intermolecular attractions verses the consistently strong intermolecular bonds between atoms.
What does mixture mean in french?
It means in french: " Mélange" A mixture (mélange) is in chemistry, a mixture is when two or more different substances are mixed together but not combined chemically. The molecules of two or more different substances are mixed in the form of mechanical mixtures, solutions, suspensions, and colloids. While there are no chemical changes to its constituents, the physical properties of a mixture, such as its melting point, may differ from those of the components. Some mixtures can be separated into their components by mechanical means. Azeotropes cannot, at least not directly.
Describe 3 ways in which a mixture is different to a compound?
1. A mixture contain two or more compounds.2. A compound is homogeneous; a mixture may be homogeneous or heterogeneous.3. Components of a mixture can be separated by physical procedures.
