A gas is initially  at volume 40.0 L, pressure 600 mmHg and temperature 35 °C. Calculate the final pressure of the gas in atm if the volume and temperature are changed to 2500 mL and 225 K, respectively.

Which of the reactions causes an increase in the temperature in the stratosphere? (A) (B) O(g) + O: (g) 0,"(g) O(g) + M (g) 0₁ (g) + (C) (D) O(g) + №z (g) - N O₂ (g) hv 20 (g) (g) (E) All of the above

What set of element contains a metalloid

Consider one mole of H2O(g) which occupies 20 L at 1 atm. Condensation of H2O(g) at 1 atm releases 30.22 kJ/mol of heat to the surrounding. Given that the density of H2O(l) at 373 K is 0.925 g/cm3 , calculate the change in the internal energy for the condensation of one mole of water at 1 atm and 373 K.
