How long from the from the start of the experiment was the substance heated before all of the substance turned into a liquid?
It is impossible to tell how long from the start of the experiment it was before all of the substance turned into a liquid without more information about the experiment. Perform the experiment again and use a timer to determine the length of time required to turn the substance into a liquid through heating.
How will I show a substance containing an element with experiments?
The field of Analytical Chemistry allows you to determine what elements are in a substance. Qualitative analysis identifies which elements are present, while quantitative analysis determines the numerical amount or concentration of each of these elements. There are many ways to perform these tests.
What is titrant and analyte?
Analyte: the substance to be analyzed by titration. Titrant: the substance (with a known concentration) added to the analyte solution to perform a titration.
What cells use to transport substance reproduce and perform chemical reactions?
energy
What is external standard method for chromatographic technique and how to perform it?
In external standard method we run a standard for the substance we are looking for in our sample and than run our sample in the same conditions. we will obtain peaks for the sample and standards and can correlate the sample with the standards and can determine the concentration of the same in our sample. for more details contact vani2007

Why do you perform an autopsy?
To determine cause of death if unknown.
Can a flask perform accurate measurements?
It depends on what flask and what the quality of it is. If there is a hole in the flask, then obviously, no measurements. Most of the time, flasks do NOT give the most accurate measurements. Although, they do give more accurate measurements than a human eyeball and flasks do have their strengths compared to other tools as well.
What are the three methods used to determine the purity of a substance?
Well you can use a melting point device in order to check if the melting point of your synthesized compound is the same as that of the literature value. You may also perform Gas Chromatography in a lab with a small sample of your compound.

Analyte: the substance to be analyzed by titration. Titrant: the substance (with a known concentration) added to the analyte solution to perform a titration.
