Consider the equilibrium system described by the chemical reaction below, which has a value of Kc equal to 280 at a certain temperature. If 0.400 mol of IBr is allowed to reach equilibrium in a 3.00 L container, what will the equilibrium concentration of IBr be

Which atom or ion is the largest? a. k b. k+ c. ca d. ca2+ e. li

What is the pressure of 0.500 moles of carbon dioxide gas in a 2.5 l tank and at a temperature of 301 k? (r=0.0821 l·atm/mol·k) 3.08 atm 1.2 atm 0.23 atm 4.01 atm 4.94 atm

If you fill your car tire to a pressure of 32 psi (pounds per square inch) on a hot summer day when the temperature is 35°c (95°f), what is the pressure (in psi) on a cold winter day when the temperature is -15°c (5°f)? assume no gas leaks out between measurements and the volume of the tire does not change.
