<span>we know that each
element has an unique spectra and it can be used to identify the
element. it shows that the energy levels of the electrons and different colors are the result of different wavelengths.
hope it helps

The overall charge will be negative 1
Answer:
Part A:
First, convert molarity to moles by multiplying by the volume:
0.293 M AgNO3 = (0.293 moles AgNO3)/1 L x 1.19 L = 0.349 moles AgNO3
Answer:
C. 0.50 mol
Explanation:
Number of mole= mass /molar mass
Mass of KF is given as 29g
The molar mass of KF= 39+19= 58g/mol
No of mole= mass/ molar mass
= 29g/58g/mol
1/2 mol= 0.5 mol
