What can be said about the shape of the infrared stretch of the O-H functional group in a carboxylic acid. Pick the best answers
kirza4 [7]

Answer: Strong (b)

Explanation:

INFRARED ACTIVE BONDS

Not all covalent bonds display bands in the IR spectrum. Only polar bonds do so. These are referred to as IR active.

The intensity of the bands depends on the magnitude of the dipole moment associated with the bond in question:

Strongly polar bonds such as carbonyl groups (C=0) produce strong bands.

Predict the gravitational and electrostatic forces between molecules of gases? Provide evidence for your prediction.
zmey [24]

the electrostatic forces are 10^{36} larger than the gravitational force

Explanation:

Let's do the calculation by using two molecules of hydrogen, each containing 2 atoms of hydrogen.

The gravitational force between the two molecules is given by:

F=\frac{G m_1 m_2}{r^2}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1 and m2 are the masses of the two molecules: since they are identical,

m_1 = m_2 = 2m_p = 1.67\cdot 10^{-27} kg, twice the mass of the proton

r is the distance between the two  molecules

The force can be rewritten as

F_G=\frac{Gm_p^2}{r^2}

We can assume instead that electrostatic force between the two molecules is given by the interaction between the positively charged nuclei and the neatively charged electrons. Therefore,

F_E=\frac{kq_1 q_2}{r^2}

where

k=8.99\cdot 10^9 Nm^{-2}C^{-2} is the Coulomb's constant

q_1 = q_2 = 2e is the magnitude of the charge of each molecule, where

e=1.6\cdot 10^{-19}C is the fundamental charge

r is the distance between the two molecules

So the force can be  rewritten as

F_E=\frac{ke^2}{r^2}

Therefore, the ratio between the two forces is:

\frac{F_E}{F_G}=\frac{ke^2}{Gm_p^2}=\frac{(8.99\cdot 10^9)(1.6\cdot 10^{-19})^2}{(6.67\cdot 10^{-11})(1.67\cdot 10^{-27})^2}\sim 10^{36}

So, the electrostatic forces are 10^{36} larger than the gravitational force.

What is the number of electrons in an atom that has 20 protons and 17 neutrons
Anni [7]

Answer:

20

Explanation:

Atoms have the same amount of electrons as they have protons. Therefore, if an atoms has 20 protons, it should have 20 electrons.

A company produces a colorless vinegar that is 5.0% HC2H3O2 in water. Using thymol blue as an indicator, a student titrates a 15
Nataly_w [17]

The negative ion in aqueous sodium hydroxide, NaOH(aq) is hydroxide ion, OH-.

<h3>What is a neutralization reaction?</h3>

A neutralization reaction is a reaction between an acid and a base to form salt and water only.

The reaction between vinegar and NaOH is a neutralization reaction which produces a salt and water only.

NaOH is composed of a positive sodium ion, Na+ and a negative hydroxide ion, OH-

Therefore, the negative ion in the NaOH(aq) used in this titration is hydroxide ion, OH-.

How might a molecule with two strong bond dipoles have no molecular dipole at all?
Reil [10]
 A molecule with two strong bond dipoles can have no molecular dipole if the bond dipoles cancel each other out by pointing in exactly opposite directions. For example, in carbon dioxide (a linear molecule), the carbon-oxygen bonds have a <span>large dipole moment. However, because one dipole points to the left and the other to the right the dipole is cancelled.</span>
