Well you see that the heat causes the crucible to blow up, almost causing an explosion. This then causes the MgNO4 gas to heat to it's 1.023 degree compound of 2 to the -2 power. The air inside of the metal makes the gas for the crucible go down and the mass changes in a way that is similar to a dog when he eats very hot grass on a very warm summer day (150 degree gas; 100 degree day).
Hope this helps,

What glasswear do you use to heat a solid?
a crucible and cover
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 would a synthesis reaction cause the mass of a product to be higher than the metal in a crucible?
Heating a metal in a crucible can cause the metal to react with the surrounding gases. thus, when weighing the metal after heating, the mass increases because of the addition of the gaseous elements
Will an empty container increase in mass when heated?
No
What is the mass of an empty 200ml beaker?
Change 200mL into decimal.
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 are 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.
What glasswear do you use to heat a solid?
a crucible and cover
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 main theme of The Crucible?
mass hysteria
What are crucible and cover used for laboratory?
The crucible is used for heating small quantities to very high temperatures.
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.
Who built The Crucible in mass effect 3?
Admiral Hackett is in charge of the Crucible. All the Scientists, Engineers, and most of the people you recruit will contribute to building the Crucible.
What is the function crucible?
Crucible is a laboratory tool which has cover, it can hold on your specimens whenever you perform a experiment. by; frisco baculio jr
Mass of empty film canister?
The mass is about 5 grams when it's empty.
How do you calculate the formula of hydrated Barium Chloride given that a sample of 10g of BaCl2.nH2O crystals lost 1.475g of of water on heating?
Mass of BaCl2 = crucible + lid + BaCl2.nH2O - empty crucible + lidMass of water contained in hydrated BaCl2: Initial mass - final massNo. of moles of H2O in hydrated salt = No. of moles = mass of H2O/formula mass of H2O Use this answer in ratioNo. of moles of BaCl2 in 3.399 g = No. of moles = mass of BaCl2/formula mass of BaCl2 Use this answer in ratioThe ratio of BaCl2 to H2O is 1 : 2
