C is a mixture!!!!!!!!!!!!!
Answer:
Concentration of nitrate in the new solution = 0.007 M
Explanation:
Given:
Concentration nitrate solution = 0.070 m
Volume of aliquote of the nitrate solution is add = 10.0 ml
Total volume = 100 ml
Find:
Concentration of nitrate in the new solution
Computation:
Number of M. mole = 0.070 m x 10.0 ml
Number of M. mole = 0.7 m-moles
Concentration of nitrate in the new solution = 0.7 m-moles / 100 ml
Concentration of nitrate in the new solution = 0.007 M
Energy is emitted when an electron falls from a higher energy level to a lower one.
The transition from 3p to 3s would emit energy because the 3s sublevel is lower than the 3p.
It’s jingju because it was established in 1955
