What pressure would have to be applied to a 27.2-mL
sample of gas at 25 °C and 1.00 atm to compress its
volume to 1.00 mL without a change in temperature?

27.2atm

Explanation:

Data obtained from the question include:

V1 (initial volume) = 27.2mL

P1 (initial Pressure) = 1atm

V2 (final volume) = 1mL

P2 (final pressure) =?

Since the temperature is constant, the gas is obeying Boyle's law.

Mathematically, Boyle's law is expressed as:

P1V1 = P2V2

1 x 27.2 = P2 x 1

P2 = 27.2atm

The final pressure is 27.2atm.

Therefore, the pressure needed to compress the gas is 27.2atm

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
