For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. System Change AS AS < 0 O AS = 0 The helium is cooled from 43.0 °C to -10.0 °C while the volume is held constant at 11.0 L. A few moles of helium (He) gas.

H+(aq) + OH-(aq) - - -> H2O (l) Use the table below to determine net ∆H for this reaction.

Q3

For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy  S  of the system, decrease  S , or leave  S  unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. System Change S A few moles of carbon dioxide (CO2) gas. The carbon dioxide is heated from 9.0 °C to 36.0 °C and also expands from a volume of 6.0 L to a volume of 14.0 L.     <S0     =S0     >S0     not enough information A few moles of helium (He) gas. The helium expands from a volume of 9.0 L to a volume of 15.0 L while the temperature is held constant at 20.0 °C.     <S0     =S0     >S0     not enough information A few grams of liquid ammonia (NH3). The ammonia is heated from -1.0 °C to 2.0 °C.     <S0…
