When H2 and CO2 react, acetic acid can be formed spontaneously while the production of formaldehyde requires an input of energy.

Which of the following conclusions may be drawn from this observation?
a. More heat is released when formaldehyde is produced compared to the production of acetic acid.
b. Compared to the reactants from which it is formed, formaldehyde has more potential energy than does acetic acid.
c. Entropy decreases when acetic acid is produced and increases when formaldehyde is produced.
d. The mineral catalyst involved in acetic acid production provides energy to make the reaction spontaneous.

Answer:

Compared to the reactants from which it is formed, formaldehyde has more potential energy than does acetic acid.

Explanation:

Some atoms tend to attain a minimum potential energy when atoms interact in certain ways. This interaction lowers the potential energy of the system involving the two atoms. This minimum energy point usually refer to overlap between atoms in a covalent bond. The closer the nuclei of the two atoms, the lower the potential energy of the bonded interaction.

If a specie takes more time to form, then it has a lower potential energy, its minima occurs much lower in the plot shown in the image attached.

An ionized helium atom has a mass of 6.6 × 10-27 kg and a speed of 5.3 × 105 m/s. It moves perpendicular to a 0.78-T magnetic fi
arsen [322]

Explanation:

In a magnetic field, the radius of the charged particle is as follows.

             r = \frac{mv}{qB}

where,   m = mass,      v = velocity

              q = charge,    B = magnetic field

Therefore, q will be calculated as follows.

         q = \frac{mv}{rB}

            = \frac{6.6 \times 10^{-27} \times 5.3 \times 10^{5}}{0.014 m \times 0.78 T}

            = \frac{34.98 \times 10^{-22}}{0.01092}

            = 3.2 \times 10^{-19} \times \frac{1.0 e}{1.6 \times 10^{-19}C}

            = +2e

Thus, we can conclude that the charge of the ionized atom is +2e.

If the % acetic acid listed on a vinegar bottle is 4%, what is the implied uncertainty of the acetic acid concentration
Tom [10]

Answer:

This question appears incomplete

Explanation:

This question appears incomplete because the data provided only makes it possible to calculate the certainty of the acetic acid content per total volume of the vinegar. Thus, the 4% means for every 100 mL of the vinegar, there is 4 mL of acetic acid present. To calculate the volume of acetic acid in any other volume of vinegar, the formula will be

volume of acetic acid = 4/100 × total volume of vinegar
