To determine the concentration of the solution of sulfuric acid, the chemist should perform titration with the use of 1.0 M NaOH. This is the answer in the space provided. The 1.0 M NaOH is suitable in the titration because it is a base, which is used in titration in order to determine the unknown concentration.
The correct option is C.
Because different elements have different masses, they also end up having different number of energy levels. Different elements emit different emission spectra when they are excited because of their unique energy levels. Each emission spectra has different color. Scientists can easily analyze the composition of a matter by analyzing its spectrum.
Because the chemical composition of the plant itself hasnt changed at all
