1. Carbon dioxide is collected over water at a temperature of 11 °C. The pressure of water vapor at 35 °C is 42.2 torr. The pressure of the collected gas (water vapor + carbon dioxide) has a pressure of 0.789 atm, what is the pressure of the carbon dioxide in atmospheres (atm)?
2. Instructions: Predict the products of the following reactants
HClO4(aq) + H20(l) =
H2SO4(aq) + H20(l) =
NaOH + H3PO4 =
