Hint: Elements are the substances made up of exactly similar types of atoms whereas mixtures are the compounds in which elements are made of more than two elements in varying ratios. In our case brass is an alloy which is made up of two metals i.e. copper and zinc in varying ratios.

 

 

Complete step by step answer: It is important to understand the word element, mixture and compound. This is because these convey useful information. Elements are the simplest chemical substances. They are made up of exactly the same atoms. Compounds are the chemical substances which are made up of more than two elements. Mixtures are also the same like compounds except for the fact that in mixtures elements are in fixed ratio in compounds whereas they are in varying ratios in compounds. Brass is an alloy of copper and zinc in varying proportions. Thus it can be concluded from the definition that brass is neither compound nor an element but a mixture. Brass is a homogenous mixture of the metals Copper and zinc. Both of the metals are bound physically. They don’t have any chemical bonding between them.

 

 

So, the correct answer is “Option B”.

Additional Information: If a substance has a fixed ratio, then only its chemical formula can be derived. But for brass the copper and zinc have metallic bonds, so there is no formula for brass. Therefore there is no symbol for brass.

Note: Never confuse between compounds and mixtures because both of them have more than two or more elements but the key point is that compounds are always in fixed ratio whereas, on the other hand, mixtures have varying proportions like brass.

Is Brass a pure substance?

While both brass and silver have a uniform composition throughout, brass is not a pure substance because it does not have a definite composition. Brass is an alloy of copper and zinc and the proportions of these two metals are varied to produce brass having different properties. 3.

Furthermore, is Brass a pure substance homogeneous or heterogeneous?

Answer and Explanation: Brass is a homogeneous mixture. It’s made when copper and zinc are mixed. It’s called a homogeneous mixture because it looks the same throughout.

Similarly, is Brass a pure solid? Brass is an alloy made primarily of copper, usually with zinc. Alloys in general may be solid solutions or they simply be mixtures. Usually you can think of brass as a solid solution consisting of zinc and other metals (solutes) dissolved in copper (solvent).

Likewise, why brass is considered as a mixture?

Brass is a mixture and not a compound because in compound the elements should be in definite proportions and the elements are chemically bonded to each other. Whereas in brass the two elements Zn & Cu are not in definite proportions (they can mix in any ratio) & there is no chemical bonding between them.

Is air a heterogeneous mixture?

mixture in which its constituents are not distributed uniformly is called heterogeneous mixture, such as sand in water. One example of a mixture is airAir is a homogeneous mixture of the gaseous substances nitrogen, oxygen, and smaller amounts of other substances. Mixtures can have any amounts of ingredients.

Is brass a compound or homogeneous mixture?

An alloy is considered as a homogeneous mixture because it is a mixture of two or more metallic elements. The composition of metals remains the same in every sample of alloy. Hence we can say that Brass is an example of Homogeneous mixture.
Is a brass nail an element?
Brass is a mixture made of copper and zinc. Mixtures occur when two metals combine to make a third metal. In this case, copper and zinc come together to make brass. Because brass does not fit the qualifications for a compound or element, the metal is a mixture.
Is brass not a compound?
Brass is a homogenous mixture of two metals Copper and Zinc. Copper and Zinc are physically bound not chemically.So,brass is a mixture not a compound.
Is brass compound or mixture Why?
Brass is an alloy of copper and zinc in varying proportions. Thus it can be concluded from the definition that brass is neither compound nor an element but a mixture. Brass is a homogenous mixture of the metals Copper and zinc.
Brass is a mixture and not a compound because in compound the elements should be in definite proportions and the elements are chemically bonded to each other. Whereas in brass the two elements Zn & Cu are not in definite proportions (they can mix in any ratio) & there is no chemical bonding between them.
What is made of brass?
It is easy to form into various shapes, a good conductor of heat, and generally resistant to corrosion from salt water. Because of these properties, brass is used to make pipes and tubes, weather-stripping and other architectural trim pieces, screws, radiators, musical instruments, and cartridge casings for firearms.
