The linear combinations that are possible when two p orbitals are combined are two.

An atomic orbital is a function in atomic theory and quantum mechanics that describes the position and wave-like behaviour of an electron in an atom. This formula may be used to determine the likelihood of locating any atom's electron in any given location surrounding the nucleus.

A linear combination of atomic orbitals (LCAO) is a quantum superposition of atomic orbitals and a method in quantum chemistry for calculating molecular orbitals. Atomic electron configurations are described as wavefunctions in quantum mechanics.

2px atomic orbital is linearly combined with 2px. Axial overlap will result in a sigma bond, whereas lateral overlap will result in a pi bond. 2px does not combine linearly with the 2py or 2pz orbitals.

Answer:

Lithium only has one pair of unpaired electrons.

Explanation:

The mass of O2 gas is about 6.9 g.

It is a law which link a gas's pressure, volume, and temperature.

The ideal gas law states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvins.

We can use this equation to find the number of moles of gas, and then use the molar mass of O2 to find the mass of the gas.

First, we can rearrange the ideal gas law to solve for n:

n = (PV) / (RT)

We know that P = 0.900atm, V = 21.4L, R = 0.08206 Latm/molK, and T = 257K.

Substituting these values into the equation:

n = (0.900atm * 21.4L) / (0.08206 Latm/molK * 257K)

Now we know the number of moles of O2 gas. To find the mass, we can use the molar mass of O2, which is 32.00 g/mol.

mass = n * molar mass

mass = n * 32.00 g/mol

So, the mass of O2 gas is about 6.9 g.

Explanation:

Answer:

This question is incomplete

Explanation:

This question is incomplete but one can assume the answer from the definition of quantum mechanics. Quantum mechanics is the science that describes particles in nature at the atomic and subatomic particle (electron, proton and neutron) level. Thus it can be assumed that atoms and subatomic particles are used to broadly describe particles.

For the given equation, the mole-to-mole ratio and volume-to-volume ratio for all the gaseous reactants and products are 1:1.

For the given equation:

CH4(g) + O2(g) → CO2(g) + H2O(g)

Reactant/Product:

CH4(g)

O2(g)

CO2(g)

H2O(g)

Mole-to-Mole Ratio:

By comparing the reactant and product coefficients, we may extract the mole-to-mole ratio from the balanced equation.

CH4(g): 1 mole

O2(g): 1 mole

CO2(g): 1 mole

H2O(g): 1 mole

All of the reactants and products have a mole-to-mole ratio of 1:1:1:1.

Ratio of Volume to Volume:

The ideal gas law, which states that under constant temperature and pressure, the volume of a gas is directly proportional to the number of moles in the gas, can be used to calculate the volume-to-volume ratio.

All gaseous reactants and products have a mole-to-mole ratio of 1:1, hence the volume-to-volume ratio will also be 1:1. As a result, the volume of drug A and substance B will be equal.

You can just take the volume of substance A as the value for substance B if you know the volume of substance A and are trying to solve for the volume of substance B. Alternatively, the quantity of substances A and Bwill be the same, given the 1:1 volume-to-volume ratio.

Answer:

3.125g/mol

Explanation:

To find the molar mass of the gas, we need to initially find the number of moles (n) contained in the gas. To find the number of moles, we use the general gas law whose equation is:

PV=nRT

Where; P= Pressure

V= Volume occupied by gas

n= number of moles

R= general gas constant

(0.0821 L atm mol/K)

T= absolute temperature

According to the question; P= 2.0atm, V= 2.0L, n= ?, T= 298K

To find n, we make it the subject of the formula:

n= PV/RT

n= 2.0 × 2.0 / 0.0821 × 298

n= 4/ 24.4658

n= 0.16mol

If number of moles (n) of the gas is 0.16mol and it weighs 0.500g, its molar mass can be found using:

number of moles (n) = mass (g) / molar mass

Making MM subject of the formula;

molar mass = mass / number of moles

MM= 0.500/0.16

MM= 3.125

Hence, the molar mass of the gas is 3.125g/mol.

Answer:

(a) 55 kJ of heat are released when 1 mol of reactant A is used;

(b) 110 kJ of heat are released when 2 moles of reactant A are used;

(c) 27.5 kJ of heat are released when 1 mol of reactant B is used;

(d) 55 kJ of heat are released when 2 moles of reactant B are used.

Explanation:

The question requires us to determine the amount of heat released when the given amounts of reactants are used, considering the following balanced chemical equation:

When the enthalpy change for a reaction (or heat of reaction, ΔH) is given in units of energy, such as kilojoules (kJ), and not units of energy per mol (such as kJ/mol), we can consider that ΔH corresponds to the heat absorbed or released for the molar quantities of reactants as given in the balanced chemical equation. In the case given by the question, for example, we can say that 55 kJ of energy are released when 1 mol of A reacts with 2 moles of B.

Therefore, we can use the molar quantitites from the balanced chemical equation as a reference to determine the amount of heat released when different amounts of reactants are used.

Considering the information above, we can calculate:

(a) heat released when 1 mol of A reacts:

Note that 1 mol of A corresponds to the amount of reactant A given by the balanced chemical equation. Therefore, 55kJ of energy are released when 1 mol of A is used.

(b) heat released when 2 moles of A reacts:

Note that 2 moles of A corresponds to the double of the amount of reactant A given by the balanced chemical equation. Thus, we must multply ΔH by 2: 55 kJ x 2 = 110 kJ of energy are released when 2 moles of A are used.

(c) heat released when 1 mol of B reacts:

Note that 1 mol of B corresponds to half of the amount of reactant B given by the balanced chemical equation. Thus, we must divide ΔH by 2: 55 kJ / 2 = 27.5 kJ of energy are released when 1 mol of B is used.

(d) heat released when 2 moles of B reacts:

Note that 2 moles of B corresponds to the amount of reactant B as given by the balanced chemical equation. Therefore, 55 kJ of energy are released when 2 moles of B are used.

The question is very complicated. In the liquid you should be able to see the solid. Anyway here is your answer. Hope it helps!

Explanation:

Mixing of Substances:

Many types of solids will dissolve into liquids under the right conditions. Certain factors will speed up the process of dissolving, including stirring the substance and heating it.

Answer and Explanation:

When a solid dissolves into a liquid, a solution is made. This happens because the solid is made up of particles that will come apart, or dissociate, in the liquid. It will appear that the solid has disappeared into the liquid, when in fact, its particles are still there. For example, salt (NaCl) easily dissolves in water. From a chemistry standpoint, it does so because the salt molecules separate into their charged ions once in the water. The ions become attracted to the slightly charged water molecules, making them stay in the solution. This process can be reversed. If the water is evaporated, the salt ions will come back together to form NaCl molecules.

Explanation:

The approximate bond angle for the H-C-H bond in CH3OH is approximately 109.5 degrees. In CH3OH, the central atom is carbon and it is surrounded by four other atoms - three hydrogens and one oxygen.

The molecular shape of CH3OH is tetrahedral, with the carbon atom at the center and the three hydrogens and one oxygen atom bonded to it. The H-C-H bond angles in CH3OH are approximately 109.5 degrees, which is the ideal bond angle for a tetrahedral shape. This is because the four electron pairs around the central carbon atom repel each other, and the molecule takes a shape that minimizes this repulsion. However, the H-O-H bond angle in CH3OH is slightly less than 109.5 degrees, at around 104.5 degrees. This is due to the lone pairs of electrons on the oxygen atom, which repel the bonding pairs of electrons and cause the H-O-H bond angle to deviate from the ideal tetrahedral angle. The bond angles in CH3OH are determined by the molecular shape and the repulsion between electron pairs. The H-C-H bond angles are approximately 109.5 degrees.

he is made with sigma bonds and pi bonds

see the answer in the photo

Answer:

Final T = 298.7K

Explanation:

In this problem, the heat given for the iron is equal to the heat that water absorbs. Using the equation:

Q = C*m*ΔT

Where Q is heat given = 270000J

C is specific heat of substance = 0.385J/gK

m is mass of iron = 1000g

ΔT is change in temperature = Initial temperature - Final temperature.

270000J = 0.385J/gK*1000g*(1000K-Final temperature)

701.3J/K = 1000K - Final T

The pH of 0.80 M KHC03 solution is 8.3.

KHC03 can act as an acid or a base. When it is dissolved in water, it will react with water to form HCO3- and H3O+ ions. \(The balanced chemical equation for the reaction is:\)

KHC03 + H2O ⇌ HCO3- + H3O+

\(The equilibrium constant expression for this reaction is:\)

Ka = [HCO3-][H3O+]/[KHC03]

Where Ka is the acid dissociation constant for KHC03.

To find the pH of the solution, we need to calculate the concentration of H3O+ ions in the solution. We can use the expression for Ka to find the concentration of H3O+ ions:

Ka = [HCO3-][H3O+]/[KHC03]

Let x be the concentration of H3O+ ions in the solution. Since KHC03 dissociates to produce HCO3- and H3O+ in a 1:1 ratio, the initial concentration of KHC03 is equal to the initial concentration of H3O+ ions, which is 0.80 M. Therefore, the concentration of HCO3- ions is also 0.80 M – x.

Substituting these values into the Ka expression, we get:

Ka = [\(HCO^{3-}\)][\(H^3O^+\)]/[\(KHC0_3\)]

Ka = (0.80 – x)(x)/(0.80)

At equilibrium, the value of Ka is equal to the ionization constant of water, Kw, which is 1.0 × \(10^{-14}\) at 25°C. Therefore, we can write:

Kw = Ka × Kb

1.0 × \(10^{-14}\) = Ka × [\(OH^-\)]

2.0

Since we are interested in the concentration of \(H^3O^+\) ions, we can use the relation:

pH = -log[\(H^3O^+\)]

Solving for x and using the relation between [\(H^3O^+\)] and pH, we get:

X = 2.8 × \(10^{-8}\) M

pH = -log(2.8 × 10^-8) = 7.55

Therefore, the pH of 0.80 M KHC03 solution is approximately 7.55, which is closest to option C 8.3.
