1. Sodium metal is also readily oxidized by oxygen. If the product of the reaction were dissolved in water, what would be the color of the litmus for a litmus test? Explain. What is the product?
2. Eliseo couldn't find the 6 M HCl and so used 6 M HNO3 for testing the metals instead. His logic? Both are strong acids. Explain how the results of the experiment would have been different.
Sulfuric acid is supplied as a concentrated liquid. A bottle was assayed and found to have a density of 1.84 g/mL and a purity of 97.0%. The molecular weight of H2SO4 is 98.0 g/mol. What is the molarity of this solution
calculate the value of delta s when 1.90 mol of rmch3 rmohl is vaporized at 64.7 circ rm
why is it easier to analyze a mixture of atomic species by absorption spectroscopy than it is to analyze a mixture of molecular species?
What volume of the stock solution (Part A) would contain the number of moles present in the diluted solution (Part B)? but I cant get this one right can someome please help.
A 14.0 L gas cylinder is filled with 8.00 moles of gas. The tank is stored at 9 degrees celsius . What is the pressure in the tank
suppose that a student performing an experiment mistakenly calibrated the pH meter using pH 6 instead of a pH 7 buffer. As a result all pH meter readings were too low.
Suppose the equilibrium constant Kc for the reaction below is 1.70x10-1 define what will be the equilibrium pressure of NO if the partial pressure of all three are all 3.15 x 10-3 atm
In an electrolysis experiment such as the one you will perform, 1.76 x 10^-3 moles of hydrogen gas were collected, and the metal electrode lost 0.1983 g. The equivalent mass of the metal is approximately what?
while a person with inherited MCAD deficiency will experience life-threatening symptoms (lack of energy and coma) after about a day of fasting
In analyzing a general unknown containing ions from several of the cation groups, a student treated the decante from Group II with Na3Co(NO2)6 and observed that a precipitate formed.
The half-equivalence point of a titration occurs half way to the end point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted.
