Answer:

The number of mole = 0.079 mole.

Explanation:

According to ideal gas equation,

PV = nRT.................... equation 1

Where P = pressure of the air, V = volume of the air, n = number of moles, R = molar gas constant, T = Temperature in (Kelvin), R = molar gas constant

Making n the subject of equation 1

n = PV/RT................... equation 2.

Where P = 101325 pa = 1 atm

V = 2.00 L = 2.00 dm³

T = 37 = 37 + 273 = 310 K, R= 0.082 atm/(dm³Kmol)

Applying these values in equation 1,

n = (2×1)/(310×0.082)

n = 2/25.42

n = 0.079 mole

Therefore the number of mole = 0.079 mole.

The dipole moment of the water molecule (H2O) is 6.17x10^-30 C.m. Consider a water molecule located at the origin whose dipole m
valkas [14]

Answer:

There are other details missing in the question. i.e Assume that x is much larger than the separation d between the charges in the dipole, so that the approximate expression for the electric field along the dipole axis E = p/2πε0y3 can be used, where p is the dipole moment, and y is the distance between ions. A) What is magnitude______N B) Direction? +x-direction or -x-direction C) Is this force attractive or repulsive?

A) Magnitude of electric force = 6.576 x 10 raised to power -13 N

B) Since the force direction is always dependent on the electric field and electric field = F/q, since the chlorine has a negative charge as such the direction of the electric force will be in the X - direction

C) Since the charges are of different nature, as such the force between them will be ATTRACTIVE.

Butanal and butanone have different chemical and physical properties primarily because of differences in their
Simora [160]

Answer: (1) functional groups

Explanation:

Functional groups are specific group of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.

The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.  

Butanal is CH_3CH_2CH_2CHO and butanone is CH_3CH_2COCH_3.

CH_3CH_2CH_2CHO and CH_3CH_2COCH_3 are functional isomers which have same molecular formula , similar masses and same number of carbon atoms per molecule but different functional groups attached.
