Answer:
One of the most common methods used today to determine the composition of stars is <u>spectroscopy</u>.
Explanation:
Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of the wavelength or frequency of the radiation.
I think it is Molar masses of compounds involved or Oxidation numbers, but you can choose one of them. Or you can think about the question carefully.
The correct answer is D . Milk
The NaOH can react with HCl with the formula: NaOH + HCl = NaCl + H2O. So if you want to neutralize the solution, the molar number of NaOH and NCl need to be equal. So we need 0.3*50/0.1=150 milliliters.
