Sulphur dioxide (50.), a gas that plays a central role in the formation of acid rain, is f ound in the exhaust of automobiles and power plants. Consider a 253L sample of gas
eous SO, at a pressure of 5 6x 10Pa, if the pressure is changed to 2.5x 10* Pa atac
onstant temperature what would be the new volume of the gas?​

The difference between the atomic number of an element and the element’s atomic mass is the number of ions.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
