Intermolecular forces operate between molecules. In contrast, intramolecular pressures are produced by molecules themselves. Intermolecular forces are less powerful than intramolecular forces. Intermolecular forces include the Interatomic force, particle contact, ion-dipole involvement, and interactions by van der Waals to name a few.

The two primary categories of intermolecular interactions are attracting forces as well as repulsive forces. Electrostatic forces are principally responsible for the attraction. The connection between four or more material elements, nevertheless, could also be caused by other factors.

The reactants are in the aqueous phase, while the product is in the solid phase and water is in the liquid phase.

Aqueous phase is a term used to describe a solution in which water is the solvent. This type of solution is commonly used in chemistry, as water is an excellent solvent for many different types of compounds. In an aqueous solution, the molecules of the solute are dissolved into the water molecules and are then evenly distributed throughout the solution. This process is driven by the strong intermolecular forces between water molecules, which allows them to attract and form strong bonds with other molecules.

Mo^3+(aq) + 3e⁻ → Mo(s)
The balanced redox reaction takes place in an acidic solution, so H+ ions are also consumed in the process. Therefore, the balanced equation is:
Mo^3+(aq) + 3H+(aq) + 3e⁻ → Mo(s) + 3H2O(l)

Option C: Neutron is the subatomic particles that could be changed without changing the identity of the atom.

The number of protons in an atom is indicated by the atomic number. As a result, when the amount of protons changes, the atomic number also changes, changing the element's identity. An element's atomic mass changes when its neutron count is altered, but its identity is preserved. An element's charge changes as its electrons are lost or acquired, but its identity is unaffected. Thus, option C is the correct choice.

Protons, neutrons, and electrons are the three subatomic particles that make up an atom. Neutrons are neutrally charged particles, whereas protons are positively charged. The opposite of this is true of electrons, which have a negative charge. Protons and neutrons are found in the nucleus of an atom.

The mass of nitric acid (HNO₃) can be determined by considering the relationship between number of moles, mass, and molar mass:

[tex]\boxed{\large\textsf{$\sf\displaystyle number\ of\ moles\ (mol)=\frac{mass\ present\ (grams)}{molar\ mass\ (g/mol)}$}}[/tex]

Rearranging this formula to find mass, therefore, mass present = number of moles ÷ molar mass:

Since we are already given the number of moles of HNO₃ present, we just need the molar mass. The molar mass of elements can be found on any standard periodic table, and the molar mass of a compound is just the sum of all the molar masses of the elements in the compound.

∴ molar mass HNO₃ = H (1.008) + N (14.01) + O₃ (3×16.00) = 63.02 g/mol.

Answer:

Explanation:

15.0 mL of vinegar is equivalent to 15.0 g of vinegar, since the density of vinegar is 1.0 g/mL. Vinegar is composed of mostly acetic acid (CH3COOH) and water. The density of acetic acid is 1.05 g/mL, so 15.0 mL of vinegar is equivalent to approximately 14.3 g of acetic acid.

The balanced equation for the reaction between sodium bicarbonate (baking soda) and acetic acid is:

NaHCO3 + CH3COOH → NaCH3COO + H2O + CO2

For every mole of acetic acid, we need one mole of sodium bicarbonate. We can use the molar mass of acetic acid (60.05 g/mol) and sodium bicarbonate (84.01 g/mol) to calculate the amount of baking soda needed.

14.3 g of acetic acid x (1 mol/60.05 g) = 0.238 mol acetic acid

0.238 mol acetic acid x (84.01 g/mol) = 19.9 g baking soda

Therefore, 19.9 g of baking soda is needed to react with the 15.0 g of acetic acid in 15.0 mL of vinegar.

To balance the redox reaction in basic solution between cyanide and silver, first write the unbalanced equation containing all the reactants and products of the chemical reaction.

Ag(s) + CN-(aq) + O2(aq) → Ag(CN)2- + OH-(aq)

Subsequently, the redox reaction is divided into partial reactions, that is, the oxidation and reduction reactions are indicated, determining the oxidation numbers of each atom that appears in the reaction.

Ag0 + C+2N-3- + O02 → Ag+1(C+2N-3)2- + O-2H+1-

The redox pairs of all atoms that have been oxidized and all atoms that have been reduced are then identified.

Subsequently, the redox couples combine in two partial reactions: one oxidation and one reduction.

Then the atoms in the partial equations are balanced by adding the appropriate coefficient in front of the formula.

Ag0 + 2CN- → Ag+1(C+2N-3)2- + e-

Next, the number of electrons lost and received is equalized, we will multiply the two equations by the factor that will give the least common multiplier.

Add the partial equations so that on one side are all the products and on the other are all the reactants.

4Ag0 + O02 + 8CN- + 4e- + 4H2O → 4Ag+1(C+2N-3)2- + 2H+12O-2 + 4e- + 4OH-

The equation is reduced by dividing by the greatest common divisor so that the coefficients are the minimum possible.

Answer: The concentration fluctuates between high and low during the reaction.

Explanation: In a chemical reaction, the reactants are converted into products and the concentrations of the species involved in the reaction change over time. The proposed mechanism describes how the reaction occurs, and it can give an insight into how the concentrations of the species change during the reaction.

When the reaction starts, the concentration of reactants is high, and the concentration of products is low. As the reaction progresses, the reactants are consumed, and the products are formed. The concentration of reactants decreases, and the concentration of products increases.

At some point, the rate of the forward reaction is equal to the rate of the reverse reaction, and the reaction reaches equilibrium. At equilibrium, the concentrations of the reactants and products remain constant, and the reaction proceeds at a steady state.

Therefore, based on the proposed mechanism, the concentration of the species represented in the equation fluctuates between high and low during the reaction, as the reactants are consumed, and the products are formed, until reaching the equilibrium state.
