6.0m x 8.0m= 48.0m
then converting it to cm by multiply
48 x 100
Methyle orange is the indicator that is used in sulfuric acid.
I think that the answer could be A. X and Y
Answer:
See explanation
Explanation:
If the energy of the ground state E1 is known, then we need to measure the difference in energy between the energy levels E5 .and E1. We can obtain this by measuring the frequency or wavelength of a photon that is emitted when an electron moves from energy level E5 to E1.
From Bohr's model;
ΔE = E5 - E1
Hence;
E5 = ΔE + E1
