Dalton's Law can be used to calculate the pressure of an individual gas present in a mixture of gases. The total pressure inside a 3 L flask containing oxygen gas (O2) and hydrogen gas (H2) at 35 °C is 105.50 kPa. (R-8.314 J K -Imol-1 ) (i) Calculate the pressure exerted by oxygen gas if the mass of oxygen gas inside the flask is 3.00 g. (M(O2) = 32 g mol-1 ) ?​

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

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 number at the end of an isotope’s name is the number.
