Calculate the pressure of Chlorine gas under Ideal and Non-Ideal conditions if you have 56 grams of Chlorine in a 3.25 liter container at a temperature of 15OC.
Given the following chemical reaction:
Ni + H2SO4 ---> NiSO4 + H2(g)
Start with 22 grams of Nickel. If the Hydrogen gas were collected over water at a pressure of 1.35 atmosphere and at a temperature of 35oC. Calculate the volume in your container that would be due to just the water vapor, and what the total volume of gas collected would be.
N2H2 + C3H4 ---> C3H8 + N2(g)
Calculate the amount of moles of N2 gas that would be produced from 12 grams of C3H4 and an excess of N2H2. If the Nitrogen gas were collected over water in a 1.2 liter container at a temperature of 29oC what would the total pressure be? How many grams of water are trapped in your container?
You need to dissolve CaCl2 in water to make a mixture that is 41.0% calcium chloride by mass. If the total mass of the mixture is 363.9g what masses of CaCl2 and water should be used
a sample of iron absorbs 67.5 j of heat upon which the temperature increases from 21.5 c to 28.5 c. if the specific
Draw all of the Lewis structures of NO2+ which obey the octet rule and use this Lewis structure or these resonance structures to predict how many covalent bonds connect each oxygen atom in the real structure to the central N atom.
Explain which mass analyzers have (a) the largest mass range (b) the smallest mass range, (c) the highest resolution and (d) the lowest resolution
Explain what is the minimum mass of ethylene glycol that must be dissolved in 14.5 kg water to prevent the solution from freezing at -23.0 Celsius. Assume ideal behavior
Question- you are asked to prepare a carbonic acid-sodium hydrogen carbonate buffer solution with a pH of 7.04. 1) What molar ratio of NaHCO3 to H2CO3 should be used. (ka = 4.2x10^-7 for H2CO3)
How many grams of NaOH must be dissolved in 250. mL of solution to produce a 2.00 molar solution of the base, A) 0.500 B) 80.0 g C) 20.0 g
Calculate the pH in a solution prepared by dissolving 0.10 mol of solid NH4Cl in .500 L of 0.40 M NH3. Assume that there is no volume change.
A gaseous reaction occurs at a constant pressure of 50atm and releases 61.5kJ of heat. Before the reaction, the volume of the system was 7.00L. After the reaction, the volume of the system was 2.60L.
An acetic acid/acetate buffer system would be the best choice for experiments at pH = 5.00. What mass of sodium acetate trihydrate (NaCH3CO2•3H2O)
In an experiment that is performed you use 1-hexene and is reacted with H2SO4 with water as the solvent. The product formed is 2-hexanol, is this an example of 1,4 addition, or proceeds via a carbanion,
Calculate the pH of 2.00L of buffer made u of 1.00 mole of sodium acetate and 1.00 mole acetic acid before and after the addition of 0.10 mole of NaOH. Assume there is no change in volume when NaOH is added
