Nitrogen and hydrogen gases react to form ammonia gas. N2(g) + 3 H2(g) 2 NH3(g) At a certain temperature and pressure 1.4 L of N2 reacts with 4.2 L of H2. If all the N2 and H2 are consumed, what vol
This reaction is sometimes used to inflate life rafts, weather balloons, and the like, where a simple, compact means of generating H2 is desired. How many grams of CaH2 are needed to generate 16.0 L
A compound, C7H12O4, has an IR spectrum showing a peak at 1735 cm-1. Its 1H NMR spectrum has peaks at delta 1.3 (6 H, triplet), 3.4 (2 H, singlet), and 4.2 (4 H, quartet). Draw its structure
A piston at 7.4 atm contains a gas that occupies a volume of 3.5 L. What pressure would have to be placed on the piston to force the volume to adjust to 1.27 L
Assume that you have a cylinder with a movable piston. What would happen to the gas pressure inside the cylinder if you do the following? Decrease the volume to one third the original volume while ho
determine its (a) electronic geometry, (b) number of nonbonding domains on the central atom, and (c) polarity of the molecule. Remember, that molecules that have zero nonbonding domains on the centr
Draw several Lewis structures and determine the geometry, bond angle, and hybridization about the central atom
Draw out the Lewis structures for H2CO3, HCO3-, and CO32-. Then determine the maximum number of equivalent resonance structures for each species. Note that carbon is the central atom in all three ca
The calcium in a second 10.00-mL aliquot was isolated as CaC2O4(s) redissolved in acid, and titrated with 12.21 mL of the EDTA solution. Assuming that 15 to 300 mg of magnesium and 50 to 400 mg calc
Mercaptoacetic acid and NH3 were introduced, production of the complex with the former resulted in the release of an equivalent amount of EDTA, which required a 22.85-mL titration with 0.07238 M Mg2
25.00 mL of 0.0200 M MnCl2 is titrated with 0.0250 M Na2H2Y. Both solutions are buffered to pH 8.20. Determine pMn after the addition of the following volumes (mL) of the Na2H2Y.
How many grams of potassium phthalate must be added to 750 mL of 0.0500 phthalic acid to give a buffer of pH 5.75?
What is the PH of 5ml 0.10 M HC2H3O2 + 5ml H2O. Can you also explain how to approximate when finding [H+].
Bibliographies and citations will be in the Chicago, MLA, or APA style. The short paper needs to be turned in through the assignment section for grading.
