What are Coombs' tests?
Coombs' tests are blood tests that identify the causes of anemia
What is used to positively identify minerals?
chemical tests and x-rays
Why are chemical properties not always used to identify minerals?
Testing the chemical properties of a mineral might damage the mineral sample. Also, these tests can be complex and may require expensive equipment.
Why are streak tests used?
Streak tests are used to identify minerals. Rubbing a mineral specimen against unglazed white porcelain, or finely powdering it and examining the powder against a white background, is a useful diagnostic test in some cases. Eg. hematite, a black mineral that looks much like many other black minerals, has a distinctive red streak.
Is Luster is a property of metals?
yes, metals are lustrous in nature.
Can transition metals be identified by their colors in flame tests?
Yes, transition metals can be identified by their unique colors in flame tests. Each transition metal emits a characteristic color when exposed to a flame due to the energy levels of their electrons transitioning. This property is used in qualitative analysis to identify the presence of specific transition metals in a sample.

What is the procedure to identify metals?
One common procedure to identify metals is through a flame test, where the metal sample is heated in a flame and the characteristic color of the flame produced can help identify the metal. Other methods include using reactivity with acids or other chemicals, measuring density, conducting an electrical conductivity test, or using spectroscopic techniques to analyze the metal's atomic structure.
Why do scientists use precipitation tests?
to identify minerals
When sodium is heated in flame it will give?
Flame tests are often used to identify metals and other substances, such as sodium. If you expose the element sodium to flame, it will give off a bright, vibrant yellow color.
What is the method identifying metal?
there are many tests but flame test, colour and spectroscopy..are the prilimnary tests for identifying metals.
What can be accomplished by neurological tests?
Neuropsychological tests can identify syndromes associated with problems in a particular area of the brain.
Why sulphur and carbon tests are done?
These tests are performed to determine the carbon-sulfur content of some metals. Certain metals comply to a specific standard due to the levels of its carbon-sulfur content.
Why cant flame test be use to identify non metals?
Non metals cannot emit a colored light.
