What mass of CaH3N can be made when 21.6 g of CaH6 react with 21.6 g of
C5H12 (l) + 8O2 (g) → 5CO2 (g) + 6 H2O (g)
1. Given 4.3 x 1024 atoms of oxygen (O), how many moles of carbon dioxide (CO2) are present? Answer with 2 sig figs.
What is the pressure of 3.5 miles of gas at 1.1 kilo pascals and 420 Kel
If pressure is expressed in atmospheres and volume is expressed in liters, PΔV has units of L atm (liters × atmospheres). Remember that 1 atm = 101,325 Pa, and that 1 L = 1 dm3. Use this information to determine the number of joules corresponding to 2 L atm.
