Question

Which of the following is the most appropriate procedure to make a 1.00 L of 0.150 M sodium solution? Add 0.150 mol sodium chloride to a one liter volumetric flask and dilute to a total add0.150 mol sodium chloride to a one liter beaker and dilute to a total volume of add 0.150 mol sodium chloride to a large container then add 1.00 L water add 0.150 mol sodium chloride to a large container then add 1000. g water Express 96,392 m using 2 significant figures. 96000.m 9.60 times 10^4 m 9.6 times 10^-4 m 9.6 times 10^4 m scientists use the SI system of measurement because it provides a uniform standard for scientific communication it conforms to the English system of measurement it prevents us from have to perform dimensional analyses non of the above chemical reaction must be balanced in order to obey the law of conservation of mass law of conservation of energy first law of thermodynamics Avogadro's law three liquids that do not dissolve in each other. Liquid A has a of 4.0 g / cm^3; liquid C has a density of 3.3 g/ cm^3. Which picture volumes of these three liquids?is the molar concentration of nitrate ions in a 0.125 M copper nitrate solution 0.125 M 0.250 M 0.0625 M 0.375 M 1 M nitric acid is added to a beaker containing 10ml of 0.5 M calcium to contents of the beaker? (a q), NO3. (a q) (a q), NO3. (a q),H^+ (a q) (a q), NO_2. (a q) (a q), NO_2. (a q), H^+ (a q)

Explanation / Answer

1) The answer is a.

2) The answer is d.

3) The answer is a. Each region in the world has different scientific units to express. It is difficult to study everything and hence it is bringed under one common scientific unit known as SI system

4) The answer is a.The chemical equation is balanced to obey the law of convervation of mass because mass cannot be created nor be destroyed

5) The answer is d. The least density will be on the top followed by increasing density below.
