A1.00 l volume of 0.10 m ammonia (nh) is titrated with hydrochloric acid (hci). calculate the ph of the solution after the addition of the following moles of hcl. there is no change in volume during the titration. the ko of ammonia is 1.8 x 10-5; the ks of nh* is 5.6 x 10-10 a) 0 moles of hci b) 0.030 moles of hci c) 0.050 moles of hci d) 0.100 moles of hci e) 0.130 moles of hci

What is the temperature of one mole of helium gas at stp?

This chart lists four kinds of polymers and their sources. what can be known about all four polymers, despite their differences? they come from living things. they share ionic carbon bonds. they are at least 100 monomers long. they are made of repeating subunits.

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.
