How do clean a beaker?

Acid washing it should do. I assume you are in a 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.

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.
