Answer:
Borax bead test
Explanation:
Another test that can be used to identify colored ions in a specific compound such as salt is called "Borax bead test".
This test involves use of a clear glassy bead of borax that is joined together in a wire loop which is going to be involved in chemical reaction with the salts of certain metals.
This reaction will produce colors that we can use to identify the exact metal ions that are present.
The answer should be E.the total number of protons and neutrons in the nucleus
<span>Two scientists wrote a paper detailing their research and conclusions and submitted it to a scientific journal. Several months later, they received the paper back from the publisher with many comments attached from several fellow scientists. It is either that they revise their study or replicate the study. Most scientists would revisit their work and the findings they had from their research. Most probable if they were successful and the comments of the publisher and the co-scientists were positive they could replicate the study to validate its accountability.<span>

Answer:
minerals are inorganic solids.
Explanation:
they have a definite chemical composition, its a solid chemical compound that occurs naturally in pure form. minerald are most commonly associated with rocks.
For a 35.83 g sample of potassium chlorate, the mass of potassium chloride is mathematically given as
M Kcl=21.62g
<h3>What is the mass of potassium chloride you expect to release upon heating?</h3>
Generally, the equation for the Chemical Reaction is mathematically given as
2KClO_3----->2KCl+2O_2
Therefore
Mole of KCl=0.29mol
Mass of Kcl=0.29*74.55
Mass of Kcl=21.62g
In conclusion, Mass of Kcl
M Kcl=21.62g
