Genetically Modified foods (GMO = Genetically Modified Organism) have been getting allot of attention in the press. GMO crops have increased crop yields and are able to feed more people. With our increasing world population there is a food shortage in not just third world countries, but industrialized nations as well.
Are Genetically Modified Foods safe and should they be banned in the USA as they has have in other industrialized countries such as Japan? Explore both sides of this topic.
Consider the chemical reaction 2NH3(g) N2(g) + 3H2(g). The equilibrium is to be established in a 1.0 L container at 1,000 K, where Kc = 4.0 ? 10-2. Initially, 1,220 moles of NH3(g) are present. Estimate the equilibrium concentration of N2(g).
How many total moles of ions are released when each of the following samples dissolves completely in water
Briefly explain how you would prepare 500.0mL of a 0.2500 M solution of chromium III ions using solid chromium oxalate and any appropriate glassware.

A sample of nitrogen gas had a volume of 500.ml, a pressure in its closed container of 740 torr, and a temperature of 25 degrees celsius. What was the new volume of the gas when the temperature was changed to 50 degrees celsius and the new pressur..
What is the number of moles of O2 needed to burn 260.0g of C2H2 in the reaction: 2C2H2 + 5O2 yields 4CO2 + 2H2O?
the titration of acetic acid with sodium hydroxide can be expressed as the combination of two reactions: the acetic acid reacting with water, and the sodium hydroxide reacting with hydronium ion.
A gas sample has an original volume of 700 ml when collected at 750 mm and 25°C. What will be the volume of the gas sample if the pressure increases to 810 mm and the temperature increases to 30°C?
calculate the molar mass of an unknown compound based on the following data. a mixture containing 1.11g of the unknown
Because of increasing evidence of damage to the ozone layer, chlorofluorocarbon (CFC) production was banned in 1996. However, there are about 100 million auto air conditioners that still use CFC-12 (CF2Cl2). These air conditioners are recharged fr..
