Juan made the following bar graph shown to represent the relative distances of four different astronomical bodies from earth. the title of the bar graph is distance of bodies in space from earth. four bars are labeled a, b, c, and d. bar c is the shortest. bar d is about three times the size of bar c. bar a is about six times the size of bar c. bar b is about eight times the size of bar c. if d represents mars, which of the following could be represented by b and c? b could be the moon, and c could be the sun. b could be the sun, and c could be the moon. b could be the sun, and c could be planet uranus. b could be the moon, and c could be planet uranus.

A6.10 m nacl can be made by adding [x]g of nacl to a container and making the volume of water up to the 1.00 l line

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.

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?
