Answer:
Emission spectroscopy is a helpful tool in determining the identity of materials in fields like forensic science because it has the ability to identify and characterize the elements in a sample obtained for forensic analysis. It accomplishes this by making the sample go through a medium that can disperse the atoms and ions in the element at specified wavelengths.
Explanation:
Atomic emission spectroscopy is a method used in the laboratory to characterize the elements found in a sample needed for a study when they pass through a flame. Inductively coupled plasma is a type of atomic emission spectroscopy which has the ability to excite the components of an element at specific wavelengths when they undergo electromagnetic radiation.
This method can identify the isotopes, atom, and ions present in a sample. This is useful in forensics as it aids the identification of the elements in the sample.
In a chemical reaction, the products should always be equal to the reactants (in this case you would answer “the same as the reactants”) since we can neither create nor destroy matter (law of conservation!)
Hope this helps! :)
Answer:
190.2 grams
Explanation:
each arrow points to the amount it weighs, just add it all up
The mass numbers for two isotopes are unequal because they have different numbers of NEUTRONS.
