Acid-base conjugate pair forms when the element donates a proton and another species acquires it. [tex]\rm H_{2}O[/tex] and [tex]\rm H_{3}O^{+}[/tex]are the base-conjugate acid pair.

Acids are the species or element and compounds that donates proton or hydrogen ions to form a conjugate base.

Bases are the elements or compounds that acquires protons or hydrogen ions and form a conjugate acid pair.

Conjugate acids and bases are the species or the products formed when the protons or hydrogen ions are increased or decreased in their chemical structures.

The reaction can be shown as,

[tex]\rm H_{2}PO_{4}^{-} + H_{2}O \leftrightarrows H_{3}O^{+} + HPO_{4}^{2-}[/tex]

From the reaction, it can be said that the water molecule acquired the hydrogen or the proton ions and the hydronium ion produced as a result is the conjugate acid of the water base.

Therefore,  [tex]\rm H_{2}O[/tex]and [tex]\rm H_{3}O^{+}[/tex]are the base-conjugate acid pair.

In the system at equilibrium liquid water-water vapor, if liquid water is added to the system, more liquid water molecules will change to water vapor until a new equilibrium is reached.

If a constraint (such as a change in pressure, temperature, or concentration of a reactant) is applied to a system in equilibrium, the equilibrium will shift so as to tend to counteract the effect of the constraint.

Let's consider the following system at equilibrium.

H₂O(l) + heat ⇄ H₂O(g)

The partial pressure of the mixture is equal to the sum of the individual pressure.The partial pressure of the remaining gas measured will be 0.8 atm.

The partial pressure of the mixture is equal to the sum of the individual pressure of the gases present in ther mixture.

The given date in the problemis

Total pressure of the mixture=P

P₁ is the partial pressure of gas 1 (N₂) =1.2 atm

P₂  is the partial pressure of gas 2(F₂)= 2.0 atm

P₃ is the partial pressure of the gas 3(H₂)=1.0 atm

P₄ Is the partial pressure of the gas 4=?

From the defination

P=P₁ +P₂ +P₃+P₄

5=1.2+2.0+1.0+P₄

P₄=0.8 atm

Hence the partial pressure of the remaining gas that was not measured will be 0.8 atm.

Answer:

Explanation:

1)The charge of one electron is given by

           1 e = - 1.6 * 10-19 C

Then – 1 C = 1 e / ( 1.6 * 10-19 )

                 = 6.25 * 1018 e

So one-coulomb charge has 6.25 * 1018 electrons

2)Let q1 and q2 be two charges separated by a distance r

Then q1 = - 40 µC = - 40 * 10-6 C

And    q2 = 108 µC = 108 * 10-6 C

The collection of  6.25 × 10¹⁸ electrons has a charge of approximately 0.100125 coulombs.

Let's break down the calculation step by step;

Charge of an Electron: The charge of a single electron is approximately 1.602 × 10⁻¹⁹ coulombs. This value represents the fundamental charge carried by an electron.

Number of Electrons: You have a collection of 6.25 × 10¹⁸ electrons. This number tells us how many electrons are present in the collection.

Calculating Total Charge: To find the total charge of the collection of electrons, we need to multiply the number of electrons by the charge of each electron:

Total charge = Number of electrons × Charge of each electron

Total charge = 6.25 × 10¹⁸ electrons x 1.602 × 10⁻¹⁹ C/electron

Calculating the Product: Multiply the numerical values and add the exponents:

Total charge = 1.00125 x 10⁻¹ C.

Final Result: The calculated total charge is approximately 0.100125 coulombs

So, the collection of  6.25 × 10¹⁸ electrons has a charge of approximately 0.100125 coulombs. This means that the combined effect of the individual charges of the electrons in the collection results in an overall charge of 0.100125 coulombs.

Based on the activity series of metals, it can be observed that Magnesium being most reactive is not dispalaced by any metal from it's solution whereas copper being the least reactive is displaced by all the metals from it's solution.

The activity series of metals is an arrangement of metals based on their reactivities, from the most reactive to the least reactive.

Based on the activity series of metals, the following will be observed:

Zinc nitrate solution + magnesium metal = Magnesium dissolves and zinc metal is obtained

Zinc nitrate solution + Copper metal = No reaction

Zinc nitrate solution + Iron metal = no reaction

Magnesium nitrate solution + Zinc metal = No reaction

Magnesium nitrate solution + copper metal = No reaction

Magnesium nitrate solution + Iron metal = No reaction

Copper nitrate solution + Zinc metal = Zinc metal dissolves and copper metal is produced

Copper nitrate solution + Magnesium metal = Magnesium dissolves and copper metal is produced

Copper nitrate solution + Iron metal = Iron metal dissolves and copper metal is produced

The phrase that defines bond energy is the energy required to break a chemical bond.

Bond energy is amount of energy needed to break the atoms involved in a chemical bond into free atoms.

The bond energy of each molecule varies with the type of bond in the molecule. Stronger bonds require a higher bond energy and vice versa.

Answer:

D. Energy input needed to break bonds of reactants.

Explanation:

Activation energy is the minimum amount of energy required to initiate a chemical reaction by breaking the bonds of the reactants. It is the energy needed to reach the transition state, where the reaction can proceed, and new chemical bonds can be formed to create the products. The activation energy is the energy barrier that must be overcome for a reaction to occur.

Once the reactants have enough energy to overcome the activation energy, the reaction proceeds spontaneously, and energy is released when new bonds form in the products.

Answer:The structure of solids can be described as if they were three-dimensional analogs of a piece of wallpaper. Wallpaper has a regular repeating design that extends from one edge to the other. Crystals have a similar repeating design, but in this case the design extends in three dimensions from one edge of the solid to the other.

We can unambiguously describe a piece of wallpaper by specifying the size, shape, and contents of the simplest repeating unit in the design. We can describe a three-dimensional crystal by specifying the size, shape, and contents of the simplest repeating unit and the way these repeating units stack to form the crystal.

The simplest repeating unit in a crystal is called a unit cell. Each unit cell is defined in terms of lattice points--the points in space about which the particles are free to vibrate in a crystal.
