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 else can I help you with?
What glasswear do you use to heat a solid?
a crucible and cover
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.
Why is it inadvisable to determine the mass of a hot crucible and lid?
Determining the mass of a hot crucible and lid is inadvisable because heating can cause volatile substances to escape or react, leading to an inaccurate measurement. Moreover, handling hot objects increases the risk of burns or accidents. It is recommended to allow the crucible to cool to room temperature before measuring its 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
A water tank has a mass of 3.64 kg when empty and a mass of 52.2 kg when filled to a certain level What is the mass of the water in the tank?
Full mass = 52.2 kgEmpty mass = 3.64 kgFull mass = (MT mass) + (water mass)52.2 = (3.64) + (water mass)Water mass = 52.2 - 3.64 = 48.56 kg
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?
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 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 purpose of taring the crucible before using it in an incineration process?
It reduces errors caused by variations in the weight of the crucible itself.Taring is accurately establishing the empty weight of the crucible, which can vary with contaminants, residue, or oxides. By repeatedly heating, cooling, and weighing the crucible, until there is only an acceptable variation between weighings, the actual weight of samples before and after incineration can be more precisely measured.
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
What is crucible cover and how it used?
a crucible is a small cup-like object used in chemistry because it can resist very high temperatures.
