What happens when sodium azide is heated?
When sodium acetate is treated with soda lime, decarboxylation takes place and CO2 is eliminated from the sodium acetate . The chemical reaction is as follows —

It's a biocide and inhibits microbial growth and also relatively cheap. The primary inhibitory effect is to inactivate cytochrome oxidase by binding to the heme group.
Although widely used, it's not universal. Sometimes other antimicrobials such as Kathon, Proclin, or thimerosal are used instead. Note that if the antibody is conjugated to HRP it cannot be used as it also inhibits HRP (also a hemoprotein).

Between 370 °C and 425 °C the substance decomposes with an exothermic energy of 758 J/g.
On heating Sodium azide around 400°C , it decomposes and releases large amount of nitrogen gas.
About 130 g of the Compound on heating releases (3 x 22.4)=67.2 litres of nitrogen gas, which is the main reason for explosion. As mentioned earlier it also releases large amount of heat energy.

The low level of sodium in the body is called hyponatremia. Sodium is an electrolyte which is important to control how much water is inside and outside the cells. Our muscles, nerves, glands, everything needs sodium to work properly.
Some symptoms a person with hyponatremia can have are:

The method involves totally anhydrous methanol, meaning all water has been removed. If any water is present it will react first, and may cause a fire when the sodium is added since the reaction will be very exothermic in that case.
Sodium is added in small portions in the form of shavings or perhaps tiny pellets. The hydrogen gas emissions commence immediately, but nowhere nearly as violently as it does in water. However, despite the slower reaction, the methanol will still warm up, so a cold bath should be made available if the reaction appears to be overheating. The reaction vessel (ideally Pyrex glass or similar) can be lowered into the water bath when needed. A magnetic stirrer should be on during the entire sodium addition phase of the reaction (Teflon-coated magnet in the methanol)
Sodium methoxide is typically left in solution rather than being isolated. Careful vacuum evaportation of the remaining methanol is the best way to get the pure sodium methoxide (a white amorphous solid) if the unreacted alcohol cannot be present in a subsequent reaction.

If you know how to use your periodic table, you know that elements in the same column have similar properties. Above Sodium is Lithium and below is Potassium. As expected, both react very energetically when placed in water. You can find lots of good YouTube videos of people exposing these metals to water.

Many (most) azides are explosive. Their explosive behavior varies from acting as “fast propellants” like sodium azide (as used in airbags) to the powerful and brisant primary explosive behavior as shown by heavy metal azides. Lead azide is one the main primary explosives in use now (in blasting caps and other detonators.) Some heavy metal azides (like copper azide to name one) are too sensitive for practical use.

Yes. Sodium is a metal and conducts heat and electricity.
Molten sodium is in fact used as a coolant for some Fast Reactors.

Because, compounds of sodium are predominantly ionic and thus thermally stable.

I have made this in my work as well as sodium ethoxide.
Methyl alcohol has a formula of CH[math]_3[/math]OH.
The hydrogen on the oxygen is the one removed by the reaction:
CH[math]_3[/math]OH + Na[math]_{(s)}[/math] → Na(CH[math]_3[/math]O) + 1/2H[math]_2[/math][math]_{(g)}[/math]

Lithium nitrate when heated decomposes to give lithium oxide and nitrogen dioxide. The reaction is as follows :
4LiNO₃ —-> 2Li₂O+ 4NO₂+ O₂
LiNO₃ on heating, gives reddish brown fumes of NO₂
