CO2 dissolves in water and reacts with the water molecules. Carbonic acid or H2CO3 is formed as a result of when the two react together.

When mixed, you get carbonated water

CO2 + H2O= H2CO3

One mole of an ideal gas doubles its volume in a reversible isothermal expansion. (a) What is the change in entropy of the gas?
Andre45 [30]

Explanation:

The given data is as follows.

       n = 1 mol,     V_{f} = 2V_{i}

       Q = 1500 J,      R = 8.314 J/mol k

(a)    \Delta S = \frac{dQ}{dT}

And, according to the first law of thermodynamics

                \Delta E_{int} = Q - W

And, in an isothermal process the change in internal energy of the gas is zero.

Hence,    0 = Q - W

or,             W = Q

Expression for work done in an isothermal process is as follows.

                   W = nRT ln \frac{V_{f}}{V_{i}}

As W = Q, Hence expression for Q will also be given as follows.

            Q = nRT ln \frac{V_{f}}{V_{i}}

Now,  

        \Delta S = \frac{nRT ln \frac{V_{f}}{V_{i}}}{T}

        [/tex]\Delta S = nR ln \frac{V_{f}}{V_{i}}[/tex]

                      = nR ln \frac{2V_{i}}{V_{i}}

                       = nR ln 2

                        = 1 \times 8.314 \times 0.693

                        = 5.76 J/K

Therefore, change in entropy is 5.76 J/K.

(b)    As,  Q = nRT ln \frac{V_{f}}{V_{i}}

                   = nRT ln \frac{2V_{i}}{V_{i}}

                   = nRT ln 2

           T = \frac{Q}{nR ln 2}

              = \frac{1500}{1 \times 8.314 ln 2}

              = 260.4 K

Therefore, temperature of the gas is 260.4 K.

Convert a pressure of 1.75 atm to kPa and to mm Hg
Serjik [45]

P = 1.75 atm = __ kPa =

_mmHg

1 atm = 760 mm Hg

We can write the two conversion factors

1 atm / 760 mm Hg or 760 mm Hg / 1 atm

1.75 atm x ( 760 mm Hg \ 1 atm)

1330 mm Hg

1 atm = 101325 pa

We can write two conversion factors

1 atm / 101325 pa or 101325 pa / 1 atm

1.75 atm x ( 101325 pa / 1 atm )

177319 pa or 177.319 kPa

Es with hydrogen
Naddika [18.5K]

Answer:

all u have to do is inserting hydrogen atoms where it's possible, if carbon is not bonded to any element, then it can have 4 hydrogens. for the first chain, the first carbon can have 3 hydrogen atoms, the second carbon 1 hydrogen atom only the third also 1 hydrogen since there is double bond and the 4th 2 hydrogen atoms
