The bond and the force present between molecules is called intermolecular force. A hydrogen bond is present between the stearic acid and a water molecule.

Hydrogen bonds are the intermolecular force that forms a dipole-dipole interaction with an electronegative atom in the presence of the lone pair of electrons.

In stearic acid, [tex]\rm C_{18}H_{36}O_{2}[/tex], hydrogen bonding exists between the oxygen and the hydrogen atom of the molecule.

Therefore, a hydrogen bond is present between stearic acid and the water molecule.

They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians), Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

Answer:

The original marshmallow was named for the inclusion of marshmallow root in the recipe. The roots and leaves of the marshmallow plant contain mucilage, a slimy-textured demulcent best known for its use as a homeopathic cough suppressant. Marshmallow root is considered to be soothing and mildly antimicrobial. It has long been used as an herbal treatment for minor digestive issues and skin irritations, although its use in the creation of its namesake confection has long since fallen by the wayside.

The theoretical yield of carbon dioxide, CO₂ obtained from the reaction is 8.93 g

We'll begin by calculating the mass of citric acid, H₃C₆H₅O₇ that reacted and the mass of carbon dioxide, CO₂ produced from the balanced equation.

H₃C₆H₅O₇ + 3NaHCO₃ —> 3CO₂ + 3H₂O + Na₃C₆H₅O₇

Molar mass of H₃C₆H₅O₇ = (3×1) + (12×6) + (5×1) + (7×16) = 192 g/mol

Mass of H₃C₆H₅O₇ from the balanced equation = 1 × 192 = 192 g

Molar mass of CO₂ = 12 + (2 × 16) = 44 g/mol

Mass of CO₂ from the balanced equation = 3 × 44 = 132 g

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂

Finally, we shall determine the theoretical yield of CO₂. This can be obtained as follow:

From the balanced equation above,

192 g of H₃C₆H₅O₇ reacted to produce 132 g of CO₂.

Therefore,

13 g of H₃C₆H₅O₇ will react to produce = (13 × 132) / 192 = 8.93 g of CO₂.

Thus, the theoretical yield of CO₂ is 8.93 g

Considering the definition of dynamic equilibrium, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

Chemical equilibrium is a state of a reaction in which no changes are observed as time passes, even though the reaction continues. That is, the chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed.

So, dynamic equilibrium is a chemical equilibrium, which occurs when two reversible processes happen at the same speed in both directions. In this way, the concentrations of the reactants and products remain constant over time.

In summary, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

Explanation:

Cr(s) → Cr3+(aq) + 3e-Ag+(aq) + e- → Ag(s)

To solve such this we must know the concept of chemical reaction. Therefore, the balanced  net cell reaction for the chromium-silver voltaic cell is Cr(s)+3Ag⁺(aq)→Cr³⁺(aq)+3Ag(s)

Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction. Chromium-silver voltaic is a cell that is used in electrochemistry.

The balanced net cell reaction for the chromium-silver voltaic cell is

Cr(s)+3Ag⁺(aq)→Cr³⁺(aq)+3Ag(s)

Therefore, the balanced net cell reaction for the chromium-silver voltaic cell is

Cr(s)+3Ag⁺(aq)→Cr³⁺(aq)+3Ag(s)

Answer:The number of BH+ Molecules will increase , and the number of water molecules will decrease

Explanation:

The number of OH- ions will increase, and the number of BH molecules will decrease.

Option (3) is correct.

In the given base solution equation, B + H₂O = BH⁺ + OH⁻, when the strength of the base is increased, more B molecules will react with water to form BH⁺ and OH⁻ ions. This happens because a stronger base donates more OH⁻ ions into the solution, increasing its concentration.

As the base becomes stronger, more B molecules will participate in the reaction, forming fewer BH⁺ molecules since they are being converted to BH⁺ ions. Simultaneously, the increased concentration of OH⁻ ions means that the number of OH⁻ ions in the solution will increase.

Overall, the change in the number of particles can be summarized as follows:

The number of BH molecules will decrease.

The number of OH⁻ ions will increase.

This change reflects the increase in the concentration of OH⁻ ions, which is a characteristic of a stronger base solution.
