Why is the iron weighed accurately on an analytical balance while the copper sulfate is weighed on a top-pan balance?
Iron may be weighed on an analytical balance because the precise measurement is important for accuracy in experiments or calculations. Copper sulfate, on the other hand, is less sensitive to small variations in weight, making a top-pan balance sufficient for its measurement.
The simplest type of balance for weighing is the?
beam balance. Two pans are suspended from each end of a horizontal beam, with the object to be weighed placed on one pan and standard weights on the other until balance is achieved.
What is the left arm pan of a platform balance used for?
The left pan of the balance can be used for counter weights. Another use might be to put an identical dish or beaker. Since taring can be error prone it would be better to counter balance.
What is the correct usage of a laboratory balance?
To properly use a laboratory balance, first ensure it is on a stable surface and leveled. Calibrate the balance using standard weights before each use. Place the object to be weighed in the center of the balance pan, close any doors or glass shields, and wait for the reading to stabilize before recording the weight.
What is the function of the balance pan?
The function of a demonstration balance is to show the basic principles of mass and force as well as leverage. Some demonstration balance tools come with weights, but are a bit more expensive.
Why need to use watch glass to measure in beam balance?
To avoid the contact between chemicals and the metal of the pan; to avoid the contamination of the pan; for an easy and total recovery of the weighed chemicals.

What is the top of a balance scale called?
The top of a balance scale is called the balance pan or balance platform. This is where the object being weighed is placed for measurement.
What is top pan balance?
It is used to compare the mass of two objects
Why are objects to be weighed placed on the center of a pan?
The objects to be weighed are placed on the center of a pan so they can be weighed accurately, without the pan tipping over.
Why should chemicals and powders not be placed directly on a balance?
Four reasons: 1) If you put chemicals on the balance pan, they will contaminate the pan. 2) A lot of balances have flat pans. If you don't put the product in something, it'll get into the mechanics of your balance and mess it up. 3) Some chemicals react violently with each other when mixed. If you measured a lot of different chemicals on your balance and some of them were to fall off the edge of the pan and mix in the mechanism, you could have an explosion. 4) It's just easier to work with powders if they're in something!

What are the advantages and disadvantages of balance scale?
A top-pan balance has the advantage of being very simple to use. The user simply places the object to be weighed on the top pan and reads the corresponding weight from the scale. A top-pan balance also has the advantage of being very accurate, as long as it is properly calibrated. A top-pan balance also has several disadvantages. First, it can only be used to weigh objects that can be placed on the top pan. Second, the top pan is often very small, which limits the size of the objects that can be weighed. Finally, top-pan balances are often less sensitive than other types of balances, which means that they are not well suited for weighing very small objects.
What is a pan balance made out of?
A pan balance is made out of two pans, two chains depending on how long youwant them, a piece of metal depending on how long you want it to be and twopieces of wood to make the stand for the scale.
What is the left arm pan of a platform balance used for?
The left pan of the balance can be used for counter weights. Another use might be to put an identical dish or beaker. Since taring can be error prone it would be better to counter balance.
What is top-load balance?
The top loading balance is used in laboratories, jewelry stores, etc.; the pan is not protected by a casing. The sensibility is up to 10 mg.
Show the labeled parts of triple beam balance?
The triple beam balance consists of three main parts: the pan, the beams with riders, and the pointer. The pan is where the object to be weighed is placed. The beams have riders that are moved to balance the weight, while the pointer indicates the weight measurement.
