which is correct

Answer:

Solute is Lithium nitrate, and solvent is water.

Explanation:

Lithium nitrate is trigonal crystal which is soluble in water.

Answer : The molar volume of the gas will be, 44.82 L

Solution :

Using ideal gas equation,

where,

n = number of moles of gas  = 1 mole

P = pressure of the gas = 0.5 atm

T = temperature of the gas = 273 K

R = gas constant = 0.0821 Latm/moleK

V = volume of the gas.

Now put all the given values in the above equation, we get the molar volume of the gas.

Therefore, the molar volume of the gas will be, 44.82 L

Answer:

The wavelength of the emitted photon will be approximately 655 nm, which corresponds to the visible spectrum.

Explanation:

In order to answer this question, we need to recall Bohr's formula for the energy of each of the orbitals in the hydrogen atom:

, where:

[tex]m_{e}[tex] = electron mass

e = electron charge

[tex]\epsilon_{0}[tex] = vacuum permittivity

[tex]\hbar[tex] = Planck's constant over 2pi

n = quantum number

[tex]E_{1}[tex] = hydrogen's ground state = -13.6 eV

Therefore, the energy of the emitted photon is given by the difference of the energy in the 3d orbital minus the energy in the 2nd orbital:

[tex]E_{3} - E_{2} = -13.6 eV(\frac{1}{3^{2}} - \frac{1}{2^{2}})=1.89 eV[tex]

Now, knowing the energy of the photon, we can calculate its wavelength using the equation:

[tex]E = \frac{hc}{\lambda}[tex], where:

E = Photon's energy

h = Planck's constant

c = speed of light in vacuum

[tex]\lambda[tex] = wavelength

Solving for [tex]\lambda[tex] and substituting the required values:

[tex]\lambda = \frac{hc}{E} = \frac{1.239 eV\mu m}{1.89 eV}=0.655\mu m = 655 nm[tex], which correspond to the visible spectrum (The visible spectrum includes wavelengths between 400 nm and 750 nm).

Answer:

The correct answer is A) carbon-carbon bonds.

Explanation:

The noncovalent interactions can generally be classified into electrostatic, π interactions, Van der Waals forces, and hydrophobic interactions. They do not share electrons, but present more dispersed variations of electromagnetic interactions between molecules or within the same molecule.

In a carbon-carbon bond, there is a covalent bond between two atoms in an organic compound. The most common form is the simple bond, which is composed of two electrons, one belonging to each of the two atoms. The simple carbon-carbon bond is a sigma bond.

Have a nice day!

Answer:

The correct option is A

Explanation:

Non-covalent interactions, from the name, means interactions that do not involve covalent interaction. Covalent interaction involves the sharing of electrons between two atoms. The bond between two carbons in organic compounds is covalent bond. The covalent interaction in itself does not permit for three-dimensional structure. Examples of noncovalent interaction include hydrogen bonds, ionic interactions, van der waals interactions and hydrogen bonds

The question is incomplete. The complete question is attached below.

Answer : The correct option is, (A) 7-chloro-3-ethyl-4-methyl-3-heptene

Explanation :

The rules for naming of alkene are :

First select the longest possible carbon chain.

The longest possible carbon chain should include the carbons of double bonds.

The naming of alkene by adding the suffix -ene.

The numbering is done in such a way that first carbon of double bond gets the lowest number.

The carbon atoms of the double bond get the preference over the other substituents present in the parent chain.

If two or more similar alkyl groups are present in a compound, the words di-, tri-, tetra- and so on are used to specify the number of times of the alkyl groups in the chain.

The given compound name will be, 7-chloro-3-ethyl-4-methyl-3-heptene.

The structure of given compound is shown below.

Final answer:

The structure given can be named as trans-7-chloro-3-ethyl-4-methyl-3-heptene.

Explanation:

The structure given can be named as trans-7-chloro-3-ethyl-4-methyl-3-heptene. The name is determined by identifying the longest carbon chain, the substituents attached to it, and their positions. In this case, the longest carbon chain has 7 carbons, with a chlorine atom attached at position 7. There is an ethyl group at position 3 and a methyl group at position 4. The presence of double bonds is indicated by the -ene ending.
