We will deal with a 1.50 g sample of a diatomic gas initially in 1.20 L balloon at 30.7 in Hg and27 degreesC.
Charles's law. You put this balloon in your freezer where it is -3.0 degrees C. When you open the freezer in half an hour, what do you expect to see - what will happen to the balloon's volume?.
(a) The volume of this balloon will (increase/decrease) (slightly/dramatically). In this experiment (pressure/temperature/amount of gas) (is/are) constant
(b) Calculate the new volume using the ideal gas law.
Making plastic drinking bottles for bottled water requires about 58 million barrels of oils per year (2007). In 2007, 300 million people averaged 114 L of bottled water per person. The average cost of 0.6 L was $1.00. The average charge for tap wa..
Question- A 1000-tonnes/da ore-processing plant processes an ore that contains 20% mineral. The plant recovers 100 tonnes/d of the mineral. This is not a very effective operation, and some of the mineral is still in the water ore (the tailings). T..
Glass is a notorious source of metal ion contamination. Three glassbottles were crushed and sieved to collect 1-mm pieces. To see howmuch Al3+ could be extracted, 200mL of a 0.05 Msolution of the metal-binding compound EDTA was stirred with 0.50 g..

How many valence electrons are there for the POCl3 molecule? Draw a reasonable Lewis structure for POCl3. Assign formal charges for the atoms in your Lewis structure. Draw a second legitimate resonance contributor for POCl3. Assign formal charges ..
A molecule of N2 in air travels at about 1000 ft/sec. If the supersonic transport Concorde travels at 1500 miles/hour, how fast does it travel in ft/sec? (1 mile = 5280 ft)
if 16.87 grams of nitric acid are reacted with a large amount of aluminum metal what volume of hydrogen gas would be
If 13.0g of CCl3F is enclosed in a 1.2-L container, what mass of liquid will be present, when the vapor pressure of CCl3F at 300K is 856 torr?
Chlorofluorocarbons (CFCs) were introduced as refrigerants in the 1930s, replacing other gases that were toxic and corrosive. How do the molecular shape and polarity of CFCs contribute to the many desirable qualities they have as refrigerants? Given ..
