1. In order for a gas to be a "greenhouse gas" it must
2. The normal process occurring on Earth that warms its surface and the lower atmosphere is called
3. Which statement about ozone and the ozone layer is true?
Ozone is found in a band of almost pure ozone several kilometers thick encircling the Earth.
The ozone in the ozone layer absorbs UV light between 200 and 300 nm. Ozone is a compound with the chemical formula CO2.
In the Earth's atmosphere, ozone exists only in the ozone layer.
4. Which one of the following reactions is an example of nitrogen fixation?
N2O5(g) ? NO3(g) + NO2(g)
N2(g) + O2(g) ? 2NO(g)
3NO2(g) + H2O(l) ? 2HNO3(aq) + NO(g)
2NO(g) + O2(g) ? 2NO2(g)
The temperature of 55.6 grams of a material decreases by 14.8 degrees C when it loses 3080 J of heat. What is its specific heat?
A solution may contain any of the Group III cations. Treatment of the solutio with CIO- in alkaline medium yields a yellow solution and a colored precipitate.
how many NH4Cl moles and how many NaOH moles would you need? About how many more moles of NaOH could you add before the buffer breaks down?
A center of chirality (from the Greek cheir, hand) imparts the property of handedness to a molecule. In this part of the experiment, the left- or right- handedness of molecules with a chiral center will be illustrated with models.
