Flame test is a qualitative test which is used to identify the metal and metalloid ion in the sample.
<h3>What is Flame Test ?</h3>
A Flame test is used to identify the metal and metalloid ion in the sample. Flame test is a qualitative test. Not every metal ion emit color when it is heated in the gas burner.
<h3>What is the Purpose of Flame test ?</h3>
The purpose of flame test is used to find the identities of ions in two solutions of unknown composition by comparing the colors they produce.
<h3>What are the material used ?</h3>
- Bunsen Burner
- Matches
- Gloves
- Weighing dishes
- Beakers
Thus from the above conclusion we can say that Flame test is a qualitative test which is used to identify the metal and metalloid ion in the sample.

#SPJ1
The name come from the German 'Bisemutum' a corruption of 'Weisse Masse' meaning white mass.
In this case, we are going to assume that there are 100 atoms to make things easier.
Let R% be the abundance of n-15. With this in mind, we calculate the abundance of n-14 to be 100%-R%
14.0031*(100-R)% + 15.001 * R%= 14.00674
In this case, we can delete or ignore the % sign since we do not want to carry it around, however, we need to keep in mind that the final answer is in %
14.0031*(100-R) + 15.001 * R= 14.00674
1400.31-14.0031R+15.001R=1400.674
0.9979R=0.364
R=0.3648
Then, the abundance of n-15 is 0.3648%
Answer:
It's false.
Explanation:
Molecular orbital theory states that the number of molecular orbitals is equal to the number of atomic orbitals that overlap. The lowest energy molecular orbital is formed when two atomic orbitals that are in phase overlap, forming a bonding molecular orbital. However, another molecular orbital is also formed, called an anti-binding orbital.
So if an "n" quantity of atomic orbitals is combined, an "n" quantity of molecular orbitals is formed.
Have a nice day!
The basic substances are called elements
