Option B. The intermolecular forces present in C4H10 are Dispersion forces and dipole-dipole forces.
What is intermolecular force?
Intermolecular forces are the forces that hold two or more molecules together, creating a compound or a substance.
There are four types of intermolecular forces :
ion-ion forces, ion-dipole forces, dipole-dipole forces, and dispersion forces, depending on the molecules involved. Each type of intermolecular force depends on the physical properties of the molecules involved in the reaction.
C4H10, also known as butane, is a chemical compound with four carbon atoms and ten hydrogen atoms. It is an alkane that is usually in gas form at room temperature and pressure.
Because it contains only nonpolar covalent bonds, butane molecules lack a permanent dipole moment, and dipole-dipole forces do not exist between them. Dispersion forces, on the other hand, do exist between butane molecules due to instantaneous dipoles. Dispersion forces occur as a result of electron movement, which can create a temporary imbalance of electrons in one molecule that induces another molecule's electrons to be attracted.
The dispersion forces in butane are weak because it is a nonpolar molecule.Therefore, the intermolecular forces present in C4H10 are Dispersion forces and dipole-dipole forces.

The intermolecular forces present in \(C_4H_{10}\) are dispersion forces only. Correct option is a.
When the charge distribution of a molecule is averaged across time, it is spherically uniform it is called a nonpolar molecule.
\(C_4H_{10}\) (butane) is a nonpolar molecule, so it does not have any dipole-dipole forces or hydrogen bonding.
Dispersion forces are described as a transient attractive force resulting from the transient dipole production in a nonpolar molecule.
The positive end of one polar molecule and the negative end of another polar molecule are attracted to one another by dipole-dipole forces.
The only intermolecular force present is dispersion forces, which are weak attractive forces between temporary dipoles in the molecules.
Hence option a. Dispersion forces only is correct.

Answers
Answer:
The structures are shown in the attachments.
Explanation:
Please see the attachments below for the structures.
Explanation:
For the structure in (a)There is only one environment denoted as 'a'.
Using the (n+1) rule to determine the multiplicity, m
where is the number of neighboring Hydrogen, then
Since, n = 0, then
m = 0 + 1 = 1 (which means singlet)
Hence, one singlet
For the structure in (b)There are two environments denoted as 'a' and 'b'
For 'a' ; n = 6
Hence, m = n + 1
m = 6 + 1 = 7 (this means septet)
For 'b'; n = 1
then, m = n + 1
m = 1 + 1 = 2 (this means doublet)
Hence, one septet, one doublet
For the structure in (c)There are two environments denoted as 'a' and 'b'
For 'a' ; n = 2
then, m = n + 1
m = 2 + 1 = 3 (this means triplet)
For 'b' ; n = 2
then, m = n + 1
m = 2 + 1 = 3 (this means triplet)
Hence, two triplets
For the structure in (d)There are three environments denoted as 'a', 'b', and 'c'
For 'a' ; n = 0
Hence, m = n + 1
m = 0 + 1 = 1 (this means singlet)
For 'b' ; n = 3
then, m = n + 1
m = 3 + 1 = 4 (this means quartet)
For 'c' ; n = 2
then, m = n + 1
m = 2 + 1 = 3 (this means triplet)
Hence, one singlet, one triplet, and one quartet

Answer: 2.00 mol
Explanation:
The balanced chemical equation is:
\(2H_2(g)+O_2(g)\rightarrow 2H_2O(g)\)
According to stoichiometry :
2.00 moles of \(H_2\) require = 1.00 moles of \(O_2\)
Thus 2.00 moles of \(H_2\) will require=\(\frac{1}{2}\times 2.00=1.00moles\) of \(O_2\)
Thus both will act as limiting reagents and will be fully consumed.
2.00 moles of \(H_2\) will form = 2 moles of \(H_2O\)
Thus 2.00 moles of \(H_2\) will form = \(\frac{2}{2}\times 2.00=2.00moles\) of \(H_2O\)
Thus 2.00 moles of \(H_2O\) will be produced from the given masses of both reactants.
If a gas effuses 2.17 times faster than Xe, what is its molar mass?
Answers
Answer:
Molar mass = 27.88 g/mol
Explanation:
The relationship between how gases effuses is given by Graham's law of effusion. This law is given as;
Rg / Rxe = \(\sqrt{}\)(Mxe / Mg)
Where;
Rg = Rate of effusion of gas g
RXe = Rate of effusion of Xe
Mxe = Molar mass of Xe = 131.29 g/mol
Mg = Molar mass of gas g
From the question;
Rg : Rxe = 2.17 : 1
Rg / Rxe = 2.17 / 1 = 2.17
2.17 = \(\sqrt{}\)131.29 / Mg
Squaring both sides
4.7089 = 131.29 / Mg
Mg = 131.29 / 4.7089
Mg = 27.88 g/mol

A. 89.7%
B. 97.1%
C. 51.5%
D. 100%
Answers
C. 51.5% is the percent yield for the reaction below when 364 g SO2 and 42.0 g O2 produce 408 g SO3
How is percentage yield calculated?The actual yield is determined by calculating the quantity of the product created. We can estimate the percentage yield by dividing the actual yield by the theoretical value. The percentage yield is the difference between the quantity of product that was actually created and the maximum calculated yield.
2SO₂(g) + O₂(g) → 2SO3(g)
SO₂ mass => 364g
O₂ mass => 42g
SO3 mass => 408g
Theoretical yield of SO3:
mole of O₂ => 42g/32g => 1.31
according to the chemical equation:
1 mole of oxygen => 2 moles of SO3
1.31 mole O2 => x moles of SO3
x=> 2 x 1.31 => 2.62
Hence, the mass of SO3 => 2.62 x 80.06 => 209.75g
The percentage of yield => Actual yield / theoretical yield x 100
=> 209.75/408 x 100 => 51.45 => 51.5%
What differs the theoretical yield from the actual yield?The theoretical yield is the yield that is derived using a balanced chemical reaction. What you actually acquire from a chemical reaction is the actual yield.

D. More thermal energy is visible when the fluorescent light bulb is lit.
Answers
A. The incandescent light bulb does not create as much as much light energy as the fluorescent light bulb.
Why do you think fluorescent bulbs are more energy-efficient than incandescent ones?Incandescent light bulbs have the drawback of wasting a lot of electricity due to heat. All the energy used to create heat is a waste because heat does not produce light, and the light bulb's intended function is to produce light. Thus, incandescent lamps are quite ineffective.
Why does a fluorescent tube produce light that is brighter and uses less energy than an incandescent lamp?Mercury vapor is excited by an electric current in the gas to produce short-wave ultraviolet light, which illuminates a phosphor coating inside the lamp. Compared to an incandescent lamp, a fluorescent lamp is far more efficient at converting electrical energy into usable light.

A. chromatography
B. evaporation
C. filtration
D. distillation
Answers
The method used to separate copper sulfate and water mixture was evaporation.
Explanation:
Chromatography is a separation technique used in labs. In this technique, there are two phases, the mobile phase, and the stationary phase. The phase in which the mixture is dissolved is termed as mobile phase and the phase which serves as a carrier through the system like, sheet, capillary, etc. is termed as mobile phase.Evaporation is a process in which the action of heat is employed to separate dissolved solids from liquid. Due to heat liquid gets evaporated leaving the solid behind.Filtration is a process in which insoluble particles are separated from the liquid by allowing them to pass through a porous substance such as filter paper. Distillation is a process used in the separation of the mixture of liquids with different boiling points.So, from this, we can conclude that the method used to separate copper sulfate and water mixture was evaporation.

How did he show that these particles had a charge on them?
Answers
J.J. Thomson discovered electrons and their negative charge through the cathode ray experiment, leading to the development of the plum pudding model of the atom.
J.J. Thomson, a British physicist, was the first to discover electrons in 1897.
He conducted the cathode ray experiment to identify the negatively charged particles.
The cathode ray tube is a vacuum-sealed glass tube with two electrodes at each end: a cathode and an anode.
When a high voltage electrical current is applied to the electrodes, the tube glows, indicating that the cathode rays are being emitted from the cathode and traveling through the tube towards the anode.
The cathode rays were found to have a negative charge, according to Thomson.
These rays were identified as particles by the presence of a magnet, which caused the particles to bend in the direction opposite to the magnet's polarity.
This discovery indicated that the particles had a charge on them because they were deflected by the magnetic field, which is only possible if the particles have an electric charge.
Thomson further concluded that these particles were about 1,000 times smaller than hydrogen atoms because of the degree of deflection they experienced in the magnetic field.
Furthermore, Thomson created the plum pudding model of an atom, in which electrons are dispersed throughout a positively charged matrix, based on his findings.
