If stored in an appropriate container and handled correctly, yes, sodium azide is safe to handle alone.
With that in mind, if not handled correctly, sodium azide can be lethal. It has an LD50 of 27ppm. NaN3 reacts violently with acids, carbon disulfide, dimethylsulfate, and metals (thus, do NOT store NaN3 on metal shevling or use metal spatulas during prep). It will also react with metal pipes, so do NOT dump down the drain.
Make sure you are wearing PPE, such as gloves, coat, goggles (not the worthless safety glasses), close-toed shoes.

A 0.200M solution of sodium carbonate Na2CO3 is made by dissolving 5.30g of the solid in water and making up the mark in a standard flask What volume must the flask be?
Flask is something that holds the sweeet nectar of alcohol
Why do you add sodium hydroxide into the conical flask containing the analgesic tablet?
to decrese ph
Why is sulfuric acid added to the dilute bleach and iodide in the conical flask during titration of sodium hypochlorite with sodium thiosulphate?
to acidify the solution
When do you add sodium hydroxide into the conical flask containing the analgesic?
when the solution turns blue you add the sodium hydroxide (also if it is not blue you have gone wrong stupid)
Why sodium hydroxide is dissolved in a little water in a beaker before transferring it into volumetric flask?
The dissolution of sodium hydroxide in water is very exothermic. One might worry the solution may boil out of the volumetric flask and cause a hazardous situation. Volumetric flasks are also fairly thin compared to a beaker and aren't designed to take much heat, if any
A flask is weighed and has a mass of 50.0 grams Then 2.0 grams of sodium metal is added to the flask Chlorine gas is pumped into the flask This allows the sodium metal to react completely with c?
5.0 grams.

to decrease ph

To combine equal numbers of sodium and chloride atoms in a flask how much Chloride would you have to add if you added 23 Grams of sodium?
23 grams of Na is close enough to 1 mole not to matter, so add 35.45 grams of Chloride ion to the flask.
When do you add sodium hydroxide into the conical flask containing the analgesic?
when the solution turns blue you add the sodium hydroxide (also if it is not blue you have gone wrong stupid)
What happens when sodium metal is dropped into a flask with chlorine gas?
If you combine pure sodium with chlorine gas, you get a violent thermogenic chemical reaction that results in NaCl (Sodium Chloride; common table salt) and considerable energy release.
How do you prepare 1000 ml 0.01 M sodium sulphate?
Dissolve 1,42 g of anhydrous, for analysis sodium sulfate in 1 L demineralized water at 20 oC, in a volumetric flask.
What is the difference between beaker and flask?
How much sodium can be perpared from 250 grams of NaCl?
250 g sodium chloride contain 99,16 g sodium.
Explain whether the rinsing of conical flask with the standard sodium carbonate would lead to experimental error?
It depends on the nature of the chemical going into the conical flask. If you are titrating for carbonate or sodium ions there could be an error. Whatever, the product going into the flask, first flush it with a little of that product. Throw it away and then titrate. However, it they have been cleaned in a lab washing machine,, by a lab. technician, then the conical flask should be 'whistle' clean. L:ab. technicians use a special water soluble of pH 7 cleaner.
