with some manipulation, the rydberg equation can be rewritten in the form

e=constant×(1nf2−1ni2)

which allows you to calculate the energy of the emitted light. express this constant in terms of the constants h, c, and rh using relationships between wavelength and energy as well as the rydberg equation from the introduction.

express the constant in terms of h and c, and rh.

me with this question?

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

its first and third is your answer i did the qustion the fourth isnt right
