Answer:
true
Explanation:
Materials science is an interdisciplinary field involving the properties of matter and its applications to various areas of science and engineering. It includes elements of applied physics and chemistry, as well as chemical, mechanical, civil and electrical engineering.
and we all know matter involve solid liquid or gas
Use the Henderson-Hasselbach equation:
pH = pKa + log[base]/[acid]
pH = -log(1.7 x 10^-5) + log(0.590/0.130) = 5.43
From the periodic table you know that Cl has a molar mass of 35.35 g/m. So if you just set up the dimensional analysis as so: (.46 moles Cl)*(35.45 grams Cl/1 mole Cl) and multiply out you get 16 grams of Cl if you follow the sig figs and 16.307 if you don't.
