One of the main components of pearls is calcium carbonate (caco3). if pearls are put into an acidic solution, they dissolve: caco3(s) + 2hcl(aq) ➡ cacl2(aq) + h2o(l) + co2(g). how many moles of caco3 can be dissolved in 0.0250 moles of hydrochloric acid?

0.0125 moles

0.0500 moles

2.50 moles

4.50 moles

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.
