Why the brass need to be immersed in the boiling water before place it in the calorimeter?
The brass needs to be immersed in the boiling water for a sufficient enough time that its temperature is the same as the boiling water, 100 degrees Celsius. That will be the initial temperature of the brass. After it is quickly placed in the calorimeter which will contain much cooler water, causing the brass to cool down and the water to heat up until the point where the temperature no longer changes. At that point the temperature of the brass is the same temperature as the water in the calorimeter, which is its final temperature of the brass.

What would happen if a piece of brass were immersed in 6 M HCL Would you expect the zinc in the brass to react leaving the copper behind?
When brass, which is an alloy primarily consisting of copper and zinc, is immersed in 6 M hydrochloric acid (HCl), the zinc will react with the acid, leading to the formation of zinc chloride and hydrogen gas. The copper in brass is relatively unreactive in comparison, so it would largely remain unaffected during this process. As a result, you would expect the zinc to dissolve, leaving behind the copper.
Is brass very ductile?
Some brass alloys are very ductile, provided they are annealed before forming; others not so.
Was bronze discovered before brass?
Bronze was probably alloyed before brass, yes. Bronze is copper and tin. Brass is copper and zinc. Bronze is the alloy most commonly found in ancient tools. But native copper itself was discovered before the alloys were.
Can brass be powdercoated?
Yes, brass can be powder coated. Powder coating can provide a durable and decorative finish for brass surfaces, helping to protect against corrosion and wear while providing a variety of color options. It is important to properly clean and prepare the brass surface before powder coating to ensure good adhesion and a high-quality finish.
What makes a brass a brass?
Brass makes Brass instruments for example, the Tuba, trumpet, euphonium,and trombone are ALL made of brass
What is The boiling point of Brass Celsius?
906 degrees
Boiling point for brass?
The boiling point of brass, which is an alloy of copper and zinc, is estimated to be between 2,700°F (1,482°C) to 2,900°F (1,593°C), depending on the specific composition of the alloy.
What are the instrumets of blues music?
Better defenitions exist, but this one works: Long Brass wailing, immersed in tears. It works even when the instrument is stringed.
What is a sentence for the word brass?
I have a pair of brass earrings and they are very heavy.
Is brass very ductile?
Some brass alloys are very ductile, provided they are annealed before forming; others not so.
What type of musical group was the forerunner of the jazz bands that develpoed in new Orleans in the late 1800s and early 1900s?
Brass bands were a popular band before that.
Was bronze discovered before brass?
Bronze was probably alloyed before brass, yes. Bronze is copper and tin. Brass is copper and zinc. Bronze is the alloy most commonly found in ancient tools. But native copper itself was discovered before the alloys were.
What is the melting and the boiling point of brass in degrees Celsius and Fahrenheit and kelvin?
Brass consists of copper and zinc ordinary yellow brass, 67% - 33% respectively, MP= 940C, 1213K, 1724F ordinary red brass, 90% - 10% resp., MP= 1050C, 1323K, 1922F other forms are in between. The boiling point, initially is assumed Zinc boiling point, 907C, 1180K, 1665F However as it is hard to expect BP below MP, then I would say the BP of brass is very near its MP, in other words, Zinc vapor exists in parallel with liquid brass. final boiling point is assumed Copper boiling point, 2336C, 2609K, 4237F
What do the initials BC mean on your ring?

What are the three properties of mixture?
1) There is no fixed composition in mixtures. Eg. Copper and tin are mixed together in variable ratios to form brass. Therefore, it is a mixture. 2) Mixtures do not have a fixed boiling point. This is due to the varying composition of its constituents. Its different constituents have different boiling points, therefore resulting in its unfixed boiling point. 3) Mixtures do not have a fixed boiling point. The reason is similar to the reason given for its unfixed boiling points. Hope this helps (: -babyhamsterx
Which instrument does not have values to change notes?
The brass instruments did not have valves before the Romantic period. Therefore, those were not chromatic instruments approximately before 1800's. Compare lines for brass instruments in Chopin's music with that of Mozart which proves the fact.
What was the French horn originalaly made from?
In the form it is currently in, brass... if you want to go back to before the horn was a horn, then copper.. bone... same as any other brass instrument.
