Which of the following best describes the relationship between gas and volcanic eruptions?
A The more gas magma contains, the more explosive a volcanic eruption will be.
B
The presence of gas in magma decreases the likelihood of a volcanic eruption.
As gas builds up in magma, volcanic eruptions occur once in the magma chamber
and once above ground
Gas found in magma determines only the intensity of eruptions involving
composite volcanoes and not shield volcanoes.
D

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced.be sure your answer has the correct number of significant digits.
