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.

How many molecules of nitrogen monoxide are in a 22.5 gram sample?
poizon [28]
Okay, so you need to start by finding the molar mass (grams in one mole) of nitrogen monoxide (NO).
N=14g
O=16g
So we know that NO has a molar mass of 30 grams, then just divide your given mass of 22.5 grams by the molar mass of 30 grams to find the number of molecules in your sample. The answer should be .75 molecules. Hope this helps!

When 2.0 mol of methanol is dissolved in 45 grams of water, what is the mole fraction of methanol
kaheart [24]

The mole fraction of methanol in the mixture is 0.444

We'll begin by calculating the number of mole of water.

  • Mass of water = 45 g
  • Molar mass of water = 18 g/mol
  • Mole of water =?

Mole = mass / molar mass

Mole of water = 45 / 18

Mole of water = 2.5 moles

Finally, we shall determine the mole fraction of methanol.

  • Mole of water = 2.5 moles
  • Mole of methanol = 2 moles
  • Total mole = 2 + 2.5 = 4.5 moles

Mole fraction of methanol =?

Mole fraction = mole / total mole

Mole fraction of methanol = 2 / 4.5

Mole fraction of methanol = 0.444

Thus, the mole fraction of methanol is 0.444

Which element decreases its oxidation number in this reaction? bicl2 + na2so4 → 2nacl + biso4?
kifflom [539]
The balanced reaction is as follows;
BiCl₂ + Na₂SO₄ --> 2NaCl + BiSO₄
this is a double displacement reaction 
the oxidation number of Bi is +2 in both BiCl₂ and BiSO₄
oxidation number of Cl is -1 in both BiCl₂ and NaCl 
oxidation number of Na is +1 in both Na₂SO₄ and NaCl
oxidation numbers of elements in SO₄²⁻ remains the same in both compounds.Therefore the oxidation state in any of the elements in the reaction doesn't change. Neither of the elements show an increase or decrease in the oxidation numbers .
Answer for this question is no element decreases its oxidation number.
