Your lab partner told you that he measured out 25.0 mL of the unknown acid solution. But he actually went above the line on the graduated cylinder (added more than 25.0 mL). Would your final calculated molarity of the unknown acid be higher, lower or equal to the actual concentration

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.

The atomic number, or number, is the described as the number of in the nucleus of an chemical element.

Who discovered a pattern to the elements in 1869?
