Answer:

A nonspontaneous process

Explanation:

The spontaneity of a reaction is given by the standard Gibbs free energy (ΔG°). We can calculate ΔG° using the following expression.

ΔG° = ∑np . ΔG°f(p) - ∑nr . ΔG°f(r)

where,

ni are the moles of reactants and products

ΔG°f(p) are the standard Gibbs free energies of formation of reactants and products

For the equation,

CO₂(g) → CO₂(aq)

ΔG° = 1 mol × ΔG°f(CO₂(aq)) - 1 mol × ΔG°f(CO₂(g))

ΔG° = 1 mol × (-386.0 kJ/mol) - 1 mol × (-394.4 kJ/mol)

ΔG° = 8.4 kJ

By convention, ΔG° > 0 means that the reaction is nonspontaneous.

Determine whether each phrase describes carboxylic acids or esters.
Thepotemich [5.8K]

Answer:

Carboxylic acids produce hydrogen bonds amongst themselves and possess lower vapor pressure. They generally possess a sour odor. When an acid and a base react with each other to produce salt and water and comprises the combination of hydrogen and hydroxide ions, the reaction is termed the neutralization reaction. Thus, when carboxylic acid reacts with base the reaction is termed neutralization.

On the other hand, esters are known for their pleasant fragrances. They do not produce hydrogen bonds amongst themselves and possess higher vapor pressure. A hydration reaction in which free hydroxide dissociates the ester bonds between the glycerol and fatty acids of a triglyceride, leading to the formation of free fatty acids and glycerol is termed saponification.

Thus, the given blanks can be filled with carboxylic acid, carboxylic acid, esters, esters, esters, and carboxylic acid.

Arrange the following compounds from left to right in order of increasing percentage by mass of hydrogen: a) H2O, b) C12H26, c)
Nuetrik [128]

Answer:

(A) N4H6  (B) H2O  (C) LiH  (D) C12H26

Explanation:

The given compounds have been arranged  from left to right in order of increasing percentage by mass of hydrogen.

The percent by mass of hydrogen can be calculated by mass of hydrogen in that compound divided by total mass of that compound and finally multiplying the result with 100 to obtain the required percentage.

Sample Response: Forces are either positive or negative vectors, depending on the direction in which the force is acting. The ne
lianna [129]

The net force is the sum of all of the forces that cancelled out to zero. Hence, option D is correct.

<h3>What is force?</h3>

The pushes or pulls on an object with mass causes it to change its velocity.

The net force is the vector sum of all forces acting on an object. Force is a vector quantity.

Two forces of equal magnitude when acting on an object in opposite directions will cancel out each other.

As a result net force is equal to 0. The word net here shows the total force acting on the object.

Hence, option D is correct.
