The men's world record for swimming 1500.0m in a long course pool( as of 2007 is 14 min 34.56 s. At this rate, how many seconds would it take to swim 0.550miles. (1 mi =1609m)
Write down the equilibrium expression for the conversion for sulpher dioxide into sulpher trioxide and rearrange this expression to give it in the form of an equation for straight line.
A 2.50 g sample of white solid was vaporized in a 345 mL vessel. If the vapor has a pressure of 985 mmHg at 180°C, what is the molecular weight of the solid.
Suppose a 80-kg person drinks 3 L of water every day for 80 years with a arsenic concentration of 50 microgram/L. PF for arsenic is 1.75 (mg/kg-day)-1. Find the daily average dosage.
