VMariaS [17]

Answer:

True => ΔH°f for C₆H₆ = 49 Kj/mole

Explanation:

See Thermodynamic Properties Table in appendix of most college level general chemistry texts. The values shown are for the standard heat of formation of substances at 25°C. The Standard Heat of Formation of a substance - by definition - is the amount of heat energy gained or lost on formation of the substance from its basic elements in their standard state. C₆H₆(l) is formed from Carbon and Hydrogen in their basic standard states. All elements in their basic standard states have ΔH°f values equal to zero Kj/mole.

above shows a balloon full of gas which has a volume of 120.0ml at 300.0k assuming pressure remains constant , what is the voume
trasher [3.6K]

128 ml  is the voume of the balloon if the temperature of the gas increases to 320.0k.

Explanation:

given that:

T1 (initial temperature) = 300K

V1 ( initial volume) =  120ml

T2 (final temperature) = 320 K

V2 (final volume) = ?

Pressure remained constant throughout the process.

From the equation

\frac{P1V1}{T1} = \frac{P2V2}{T2}

Since pressure is constant the equation will be:

\frac{V1}{T1} = \frac{V2}{T2}

V2 = \frac{V1 X T2}{T1}

    Putting the values in the above formula:

V2 = \frac{120 X 320}{300}

     = 128 ml

128 ml is the volume of the gas if temperature increases from 3OO K to 320k
