Can NaCl and NaNO3 make a buffer solution? Explain why or why not. Why is HCl called a polar molecule? Explain your reasoning. Why does the heat of dissolution of NaCl need to be considered when NaCl is being used as a deicer?
If Na has a mass of 23, and Cl a mass of 35, how many grams of NaCl are added to water to make one liter of a 3 M solution? How many moles of solute are present in 175 mL of 0.35 M NaNO3? How many grams of solute are in 0.504 L of a 0.350 M K_2CO_3...
NaCl and NaNO3 solutions. KI and Na2SO4 Compare and contrast the different types of distillation. Describe the difference between infrared and Raman spectroscopy. Why are they considered complementary to each other? Why do cis and trans isomeric co...
Solubility describes the amount of a substance that can be dissolved in another substance. This measurement can range from nearly completely insoluble under any conditions, such as oil and water, to near infinitely soluble, such as ethanol and water. The process of dissolving should not be confuse...
Alternate sources of nitrates include: Chile saltpeter, an impure form of sodium nitrate (NaNO3), which was deposited along the Pacific coast by large flocks of birds which nested (and went to the bathroom) for thousands of years, & Lime saltpeter (Norwegian saltpeter) which is composed of ...
A saturated solution of NaNO3 is prepared at 60 degrees, using 100 grams of water. As this solution is cooled to 10 degrees, NaNO3 precipitates out of the solution. The resulting solution is saturated. Approximately how many grams of NaNO3 settled out o...
Which compound is an electrolyte? A) HCl B) NaCl C) HBr D) All of the above Electrolytes: If we can dissolve a compound in a polar solvent such as water such that the cation-anion pairs of the compound are released into the solution, that compound is an electrolyte...
How much solvent would you need to prepare 115 g of 13% NaNO3 solution by mass? What mass of water must be used to dissolve 20.0 grams of ethanol, C_2H_5OH, to prepare a 0.0500 molal solution (molality) of ethanol? A) 3.76 kg. B) 4.00 kg. C) 8.70 kg. D) 6.35 kg....
Ba(NO3)2(aq) + NaCl(aq) = BaCl2(s) + NaNO3(aq) Which type of chemical reaction does this word equation exemplify: when exposed to sunlight, nitrogen dioxide changes to form nitrogen monoxide and oxygen? What type of reaction is the reaction between N...
