<u>The flask assembly will heat up in hot water, pressure will build up inside the flask and it could </u><u>explode.</u>
- The fingertip is kept in place throughout the transfer to prevent the seepage of the trapped air from the flask.
- Inside the tank, the flask is constantly upside down. The flask can be tipped at an angle to allow the air to escape.
- The entire contents of the pint will erupt out if only the bottom of the container is heated.
- Rubber stoppers are ideal for plugging joints or holes in laboratory glassware and creating a liquid-tight seal.
What is the proper method for inserting glass tubing into a rubber stopper?
- Lubricate the end of the glass tubing with a few drops of water, washing-up liquid, glycerol, or vegetable oil.
- Hold the glass tubing close to where it enters the hole in the rubber stopper.
- Ease the tubing into the hole with a gentle twisting motion.

Molarity of solution is defined as number of moles present in one liter solution. Mathematically, it is expressed as
Molarity =
Thus, if 1 mole of solute is present in 1 liter solution, molarity of solution is 1 M.
In present case, initial conc, of solution was 1.25 M.
∴ Number of moles of <span>co[h2o]6cl2 available initially = 1.25 mole, if the solution is 1 liter</span>
Alteration of the physical form of a drug outside its label is compounding
It is called compounding according to some sources.
Answer:
Generally, a gas behaves more like an ideal gas at higher temperature and lower pressure, as the potential energy due to intermolecular forces becomes less significant compared with the particles' kinetic energy, and the size of the molecules becomes less significant compared to the empty space between them.
Explanation:
