Fire polisihing is used for the polishing of glass tube ends or other glass laboratory components; it is possible to use this method also for plastics.
The results cannot be applied to human beings.
decomposition of hydrogen peroxide using a catalyst, commonly manganese(IV) oxide
Because laboratory equipment must be very clean.
when psychologists observe behavior in a laboratory rather than in the field.
There are many methods of the data collection: 1. experimental method in the laboratory 2. survey method

FALSE t(n.n)
The most effective method for cleaning laboratory equipment using a wash solvent is to thoroughly rinse the equipment with the solvent multiple times, ensuring all residues are removed.
Fire polisihing is used for the polishing of glass tube ends or other glass laboratory components; it is possible to use this method also for plastics.
The most accurate method for determining protein concentration in a laboratory setting is typically through the use of a spectrophotometer, specifically by measuring absorbance at a specific wavelength using a known protein standard curve. This method allows for precise quantification of protein concentration in a sample.
The results cannot be applied to human beings.
Ethane can be prepared in the laboratory by reacting sodium ethoxide with ethyl iodide in anhydrous conditions. Another method involves the reaction of sodium acetate with sodium hydroxide followed by treatment with sulfuric acid to yield ethane gas.
