Why do you have to dry the Erlenmeyer flask at the start of the experiment?

A flash or glass tubing should be dry at the start of each trial to ensure accurate results. Any contaminants can effect the results directly.

Why Erlenmeyer flask does not have to be dry and why water may be added?
- Depending on the specifications for the experiment the Erlenmeyer flask may be dry or not - Water is added only if the recipe need water

How do you write a hypothesis about dry ice experiment?
The answer for hypothesis is where you do your experiment and then you look back at your problem then that's when you get your hypothesis . LOL :) have a great day
How can you keep the inside of your pewter flask from rusting or corroding from the inside out?
Pewter corrodes when it is placed in a humid environment that allows a film to develop over the metal. Under the film, the pewter will begin to corrode. My suggestion would be to rinse the flask with cold water, and allow it to dry completely before resealing the lid. If you live in an environment where you have humid, hot summers, I might even place the flask in the refrigerator as it drys. Try using some sort of rack that allows the flask to stay upside down, ensuring that all water can escape (gravity) and air can freely circulate (keeps humidity low). Never add anything other than alcohol, like a mixed drink or mixer, as these liquids are harder to clean and dry, and can allow films to develop if the flask if full for long period of time. Hope this helps!

Why the Erlenmeyer flask does not have to be dry and why water may be added after the 25.00-centimetre Cube of Acid has been pipetted in?
?
How do clean a beaker?
Acid washing it should do. I assume you are in a lab...in which case a 1:1 Hydrochloric Acid solution can be poured into the flask. DON'T FORGET TO PUT GOGGLES AND GLOVES ON. Put the lid on. Shake the flask and turn it to ensure all surfaces of the glass inside are being washed with the acid. Then, give it a good triple rinse with de-ionized water. If you are just at home, pour in some white vinegar and let it sit for a while. That should break up anything that's inside.
What will happen if a wet Erlenmeyer flask is used to transfer acid solution from the volumetric pipette?
It will slip out of your hands, fall to the floor, break, and cause the principal to evacuate your whole school until the fire department comes to neutralize the spill. Keep your flasks dry, please.
Is it necessary to dry clean the conical flask before use?

Can you use ice instead of dry ice in cloud chamber experiment?
No, you can not use ice instead of regular ice in the cloud chamber experiment. It would not react the same way. Dry ice is frozen carbon dioxide, the cloud chamber experiment relies on the sublimation of solid CO2 into gas.
