Octadecane C18H38 is a component of diesel. Its concentration in a sample of rainwater was found to be 0.3 ppb (parts per billion). If the density of water is 1g mL-1 find the molar concentration of C18H38?

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
