Also the beginning and ending temperatures and the pressures involved, the volume being known and constant.
room temperature
measure the weight of the flask and take care not to breathe in any of the purple gas (could be iodine vapour).
Laboratory flask of different types are designed to contain liquids in larger volumes.
Alpha particles are helium-4 nuclei; they do not contain electrons.
The conclusion was that an atom contain a positive nucleus.

a laboratory beaker is a laboratory tool which is ued to heat an liquids up or to contain liquids...
The control does not contain a variable!:)
Laboratory flask of different types are designed to contain liquids in larger volumes.
Each step of the experiment.
The element of an experiment that doesn't contain the variable is called the "control"
common rocks contain sulfur
Very simple , a glass rod soaked in ammonia solution bring to the mouth of both the bottles mutaric acid (HCl) gives white fumes while vinegar does not.
- to contain liquids in a laboratory - to realize chemical reactions - to collect the solution from a filtering installation - to realize titrations etc.
Laboratory wares are used for measurements and experiments. Laboratory wares are typically used to contain liquids and gasses, and are manufactured to withstand extreme temperatures. There are many different types of laboratory glasswares and plastic-wares sold and used.
