What happens when sunlight strikes a photovoltaic cell?
a: electrons are released, causing a flow of electrical current
b: atoms are split, resulting in a release of energy
c: small tubes of water are heated, producing flow of energy

What shape would a molecule with two bound groups and two lone pairs have?

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.

Which symbol can be used to indicate the pressure at which a chemical reaction is carried out? 25°c 2 atm pa
