The formation of acetic acid from carbon dioxide and hydrogen is a spontaneous reaction, meaning it occurs naturally without any external energy input. This reaction is exothermic, meaning it releases energy in the form of heat.

If the statement were changed to say that the reaction was non-spontaneous, meaning it requires an external energy input to occur, then one possible reason for this would be that the reaction has a high activation energy barrier. In this case, the reaction may not occur without an energy source to overcome this barrier, such as high temperatures, pressures, or catalytic agents.

However, based on current scientific understanding, the formation of acetic acid from carbon dioxide and hydrogen at hydrothermal vents is believed to be a spontaneous reaction that is catalyzed by minerals found in the vents. The reaction is thought to occur in the presence of metal sulfides and other minerals that act as catalysts, lowering the activation energy barrier and allowing the reaction to proceed more readily.

The minimum amount of energy required for a chemical reaction to occur is known as activation energy. The energy barrier must be crossed for a reaction to progress from reactants to products.

In other words, it is the amount of energy required to break the bonds of the reactant molecules and form new bonds in order to form the product molecules.

On a reaction energy diagram, the activation energy is typically represented as a barrier, with the reactants on the left side, the products on the right side, and the activation energy barrier in between. The reaction rate is determined by the height of the activation energy barrier; the higher the barrier, the slower the reaction rate, and the lower the barrier, the faster the reaction rate.

In general, increasing the temperature, pressure, or concentration of reactants increases the probability that reactant molecules will have enough energy to overcome the activation energy barrier and undergo the reaction. Catalysts can also lower the activation energy barrier, allowing the reaction to happen faster and more efficiently.

If water is produced from the reaction of hexane and of oxygen gas, then the percent yield of water is 8.6%.

The balanced equation for the reaction between hexane and oxygen to form carbon dioxide and water is:

C₆H₁₄ + 19/2 O₂ → 6CO₂ + 7H₂O

The stoichiometric ratio between hexane and water is 1:7, which means that for every 1 mole of hexane, 7 moles of water are produced.

If 0.30 moles of water are produced from the reaction of 0.50 moles of hexane and excess oxygen gas, then the theoretical yield of water is:

0.50 moles hexane × (7 moles H₂O / 1 mole hexane) = 3.5 moles H₂O

The percent yield of water is calculated by dividing the actual yield of water by the theoretical yield of water and multiplying by 100%:

percent yield =(actual yield/theoretical yield) × 100%

percent yield = (0.30 moles H₂O / 3.5 moles H₂O) × 100%

The molar mass of carbon dioxide is 44.01 g/mol, which means that 1 mole of carbon dioxide contains 6.022×10^23 molecules. Therefore, the number of moles of carbon dioxide present in 52.06 g of the compound can be calculated as follows:

Number of moles = Mass/Molar mass = 52.06 g / 44.01 g/mol = 1.182 mol

Each molecule of carbon dioxide contains one carbon atom and two oxygen atoms. Thus, the total number of oxygen atoms in the sample can be calculated by multiplying the number of moles of carbon dioxide by the number of oxygen atoms per molecule and Avogadro's number (6.022×10^23):

Number of oxygen atoms = 2 × Number of moles × Avogadro's number

= 2 × 1.182 mol × 6.022×10^23

The energy stored in chemical bonds of a molecule that can be used to make new bonds in a different molecule is called chemical potential energy.

When a chemical reaction occurs, the reactant molecules have a certain amount of chemical potential energy stored in their bonds, and this energy is either released or absorbed as new bonds are formed in the product molecules. The amount of chemical potential energy stored in a molecule depends on the types and arrangements of atoms in the molecule, as well as the strength of the chemical bonds between them.

The strength of the chemical bonds in a molecule depends on several factors, including the types of atoms involved, the number and arrangement of electrons around those atoms, and the way in which those electrons are shared or transferred between the atoms to form the bond. Bonds that involve the sharing of electrons, such as covalent bonds, tend to be stronger than bonds that involve the transfer of electrons, such as ionic bonds.

Chemical reactions occur when reactant molecules come into contact with one another and the energy stored in their chemical bonds is either released or absorbed as new bonds are formed in the product molecules.
