Answer: The correct answer is Option A.

Explanation:

Dispersion is defined as the splitting of white light into seven colors of the rainbow which is VIBGYOR.

As, we know sunlight is the white light and when it passes through droplets of water, the light splits into seven colors and hence, the droplets of water acts like prisms.

Polarization is defined as the property of a certain electromagnetic radiation which relate the direction and magnitude of vibrating electric field.

Absorption is defined as the process in which one substance gets soaked up on the other substance.

Interference is defined as the process in which waves of the same frequency combines to support or cancel each other resulting in the summation of the amplitudes of the two waves.

Hence, the correct answer is option A.

What volume. In liters, of H2O(g) measured at STP is produced by the combustion of 15.63 g of natural gas (CH4) according to the

fomenos

Answer:

V = 43.95 L

Explanation:

Given data:

Mass of CH₄ decomposed = 15.63 g

Volume of H₂O produced at STP = ?

Solution:

Chemical equation:

CH₄ + 2O₂ → 2H₂O + CO₂

Number of moles of CH₄:

Number of moles = mass/molar mass

Number of moles = 15.63 g/ 16 g/mol

Number of moles = 0.98 mol

Now we will compare the moles of H₂O with CH₄.

CH₄ : H₂O

1 : 2

0.98 : 2×0.98 = 1.96 mol

Volume of hydrogen:

PV = nRT

1 atm × V = 1.96 mol × 0.0821 atm.L/mol.K × 273.15 K

V = 43.95atm.L / 1atm

V = 43.95 L

Would the ph at the equivalence point be acidic, basic, or neutral for each given titration?.

Lesechka [4]

Answer:

At the equivalence point, equal amounts of H+ and OH– ions will combine to form H2O, resulting in a pH of 7.0 (neutral). The pH at the equivalence point for this titration will always be 7.0, note that this is true only for titrations of strong acid with strong base.

Draw a lewis structure for ketene, c2h2o, which has a carbon–carbon double bond

MrMuchimi

Visual representation of covalent bonding indicating the valence shell electrons in the molecule, lines represents the shared pair of electron and pair of electrons that are not involved in bonding are represented as dots(lone pairs) are known as Lewis structures.

Compound formation takes place in order to complete the octet of each element that is according to octet rule, each atom forms bond with other atom in order to complete their octet that is to get eight electrons in its valence shell and attain stability.

An organic compound of the form $R^{'}R^{''}C=C=O$ is known as ketene.

The given ketene is $C_2H_2O$ .

The number of valence electron of:

$C = 4$

$H = 1$

$O = 6$

The number of valence electrons in $C_2H_2O$ = $2\times 4+2\times 1+1\times 6 =16$

2 electrons are involved in each single bond between carbon and hydrogen and 4 electrons are involved in each double bond formed between carbon-carbon and carbon-oxygen. Hence, the total number of electrons involved in bond formation are 12 and rest 2 pair of electrons are present on oxygen as lone pair of electrons.

Therefore, the attached image is the Lewis structure of $C_2H_2O$ .

What is the wavelength of a 3 x 1012 Hz infrared wave?

Alenkasestr [34]

Answer:

Explanation:

wavelength = speed of light/ frequency

= (3 x 10^8 m/s) / (3 x 10^12 Hz)

= 1 x 10^-4 m
