Why must chemicals are never placed directly on the balance pans?
Chemicals must be placed on weighing paper to correctly mass the total amount. Also, this reduces loss of chemicals weighed. ...

Why can't chemicals be placed directly on the balance pans?
To keep the balance clean and to keep chemicals from mixing with other chemicals. Also some chemicals can react with the metal of the balance pan and cause it to corrode or rust. Always use weighing paper or a small dish or beaker to weigh out chemicals. ...

Why are chemical never placed directly on the balance pan?
Certain chemicals can corrode the balance pan. It's also difficult to transfer what you have weighed, with any accuracy, from the balance to its destination. ...

Why are wet objects never placed on a balance pan?
Wet objects should never be placed on a balance pan because they might react with the material of the pan and cause it to become corroded. ...
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...

What are the objects that are viewed through a microscope placed on?
In compound microscopes for use for viewing thin sections at high power, specimens are mounted on a microscope slide and covered with a coverslip and are placed on the microscope stage or base plate. In stereomicroscopes the same is done however for large objects such as rocks or minerals no microscope slide is required the object to be observed is placed directly on the stage. ...

Regulations to control emission of chemicals for ozone depletion?
Regulations to control emissions for chemicals have been placed. These chemicals might deplete it. ...

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. ...
If you had one pound of rocks and one pound of feathers which one would weigh more?
Neither of them would weigh more. Their weights would be equal, namely, one pound each. At the same height above ground, both objects would have the same gravitational potential energy. Placed on the end of a see-saw, both objects could balance the same load on the other end. For that matter, if both objects were placed on opposite ends of a symmetrical see-saw, they would balance each other, because their weights are the same. ...
What pairs of objects would have the strongest gravitational pull?
Gravitaion is dependant on two main things: distance between the objects and their mass. More massive objects placed closer together will have more gravitational pull than less massive objects, or objects of the same mass placed further apart. ...
An object most likely sink in water if it has low density?
The lower an objects density the less likely it is to sink in water. Objects with a higher density than water will sink if placed in it while objects with a lower density than water will float if placed in it. ...
How do neutral objects behave when placed near charged objects?
A separation of charges can be induced in neutral objects. This will cause a dipole, and an attraction towards the charged object. ...
