When cuso45h2o is heated in a crucible there is a loss of water how is the amount of water loss determined?
Weigh mass before heating and weigh mass after heating. Before mass - after mass.
How do you know when a heated crucible has returned to room temperature?
holding your hand about 1 cm above the crucible to test is still hot..Caleb!
What element combines with Magnesium when heated in a crucible?
oxygen...it forms magnesium oxide
Uses of clay triangle?
The clay triangle is used to hold a crucible while the crucible is heated.
What items is used to distribute heat from a Bunsen burner when heating the bottom of a crucible?
A crucible is placed in a pipestem triangle placed on an iron ring while being heated. This supports the crucible while allowing the bottom of the crucible to be directly exposed to the flame of the Bunsen burner. There is no item that is used to distribute heat from a Bunsen burner when heating the bottom of a crucible. The bottom of the crucible is intended to be exposed to the direct flame of the Bunsen burner.
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.
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 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.

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.
How can you determine the amount of salt presented in a saturated solution?
Only by experiments. For example the solution is heated, water is evaporated and the salt weighed.
