What else can I help you with?
Why should the crucible be heated to constant mass?
We want to weight exactly only the material - variations of the crucible mass lead to errors. That's why the mass of the crucible must be stabilized.This is very important in gravimetry, it is a basic rule.
What combined wih the magnesium when it was ignited in The Crucible?
oxygen. O2 was combined with magnesium when it ws heated in the crucible
Why is it necessary to cover The Crucible by Arthur Miller when it is being heated?
It is necessary to cover the crucible when it is being heated for two basic reasons: primarily, it maintains a higher temperature inside the crucible. Without the lid, the heat simply escapes. Secondly, it keeps the material inside the crucible from splashing out.
What is the mass of an empty crucible?
The mass of an empty crucible can vary depending on its size and material. Typically, a small ceramic or metal crucible may weigh between 10 to 100 grams. For precise measurements, it's best to weigh the crucible on a balance scale before adding any substances for experimentation.
Why the empty crucible and cover fired to red heat?
To drive off any volatile materials that might alter the mass of crucible and cover.
WHY EMPTY CRUCIBLE HEATED BEFORE STARTED EXPERIMENT?
The empty crucible is heated AND WEIGHED, so that you can drive off any moisture and/or other particles that might add to the weight of the empty crucible. You will eventually weigh the crucible again at the end of the experiment to determine the weight (mass) of some compound. Thus, it is important to have a correct "starting mass" of the crucible.
Why are the empty crucible and cover fired to red heat?
Firing the empty crucible and cover to red heat removes any moisture and contaminants that may be present on the surfaces. This helps ensure a clean and consistent environment for subsequent experiments or material processing.
Why should the crucible be heated to constant mass?
We want to weight exactly only the material - variations of the crucible mass lead to errors. That's why the mass of the crucible must be stabilized.This is very important in gravimetry, it is a basic rule.
What is the use of crucible?
A crucible is used to contain chemical compounds when heated to extremely high temperatures.
What are the uses of clay triangle?
Clay triangle is used to hold a crucible while the crucible is heated.
Why evaporation is faster from a heated crucible?
because it is faster
What element combines with Magnesium when heated in a crucible?
When magnesium is heated in a crucible, it combines with oxygen from the air to form magnesium oxide (MgO).
What combined wih the magnesium when it was ignited in The Crucible?
oxygen. O2 was combined with magnesium when it ws heated in the crucible

Uses of triangular clay in science lab?
The clay triangle is used to hold a crucible while the crucible is heated.

Will an empty container increase in mass when heated?
No, an empty container will not increase in mass when heated. Heating an empty container will not create additional matter within the container to increase its mass.
