Poisson's ratio... a) is a method to relate the longitudinal deformation of a material with its simultaneous lateral deformation

b) ..is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space c) is a dimensionless number equal to the change in length of a specimen, divided by the original length d) .typically has low values for polymers, and high values for metals

Answer:

The Poisson's ratio (ν) is a method to relate the longitudinal deformation of a material with its simultaneous lateral deformation.

Explanation:

The Poisson's ratio (ν) is a method to relate the longitudinal deformation of a material with its simultaneous lateral deformation.

It can be expressed as

\nu=-\frac{\epsilon_{trans}}{\epsilon_{long}}\\

It is a measure of the Poisson effect, in which a material tend to expand in directions perpendicular to the direction of compression.

A balloon occupies 1.50 L with 0.205 mol of carbon dioxide. How many moles would be required to increase the size of the balloon
Gekata [30.6K]

Answer:

0.683 moles of the gas are required

Explanation:

Avogadro's law relates the moles of a gas with its volume. The volume of a gas is directely proportional to its moles when temperature and pressure of the gas remains constant. The law is:

V₁n₂ = V₂n₁

<em>Where V is volume and n are moles of 1, initial state and 2, final state of the gas.</em>

<em />

Computing the values of the problem:

1.50Ln₂ = 5L*0.205mol

n₂ = 0.683 moles of the gas are required

Devices that mix air or oxygen with flammable gasses cannot be used unless approved by
Feliz [49]

Flammable gases are gases that have the tendency to <u>explode (burst into flames)</u> when they come in contact with the <u>appropriate quantities of air, oxygen, or any suitable oxidant.</u>

<u />

<u />

Devices that mix air or oxygen with flammable gasses cannot be used unless approved by an <u>authorized or approved personnel.</u>

<u></u>

<u></u>

  • Examples of flammable gases are hydrocarbons such as <u>Propane, Acetylene</u>, e.t.c.

  • Flammable gases are dangerous to humans and the environment and if they are not handled properly, can cause severe damages and even death.

  • During the preparation and usage of flammable gases, safety precautions should be properly enforced such as the <u>wearing of appropriate safety gear and goggles</u>.

  • Devices that mix air or oxygen with flammable gases cannot be used unless approved by an <u>authorized or approved personnel.</u>

Suppose you have crude reaction mixture containing napthalene, benzoic acid, and aniline dissolved in an organic solvent, and yo
Leto [7]

Answer:

d. Adding 5% HCl solution to the crude reaction mixture will protonate aniline increasing its solubility in the aqueous solution.

Explanation:

On this case, we have to check the <u>structures of each compound</u> (figure 1). For naphthalene we dont have <u>any functional groups</u> therefore, the addition of HCl or NaOH it will not affect naphthalene so <u>we can discard "B" and"C".</u>

When we add HCl solution we will have the production H^+ the presence of this <u>hydronium ion will protonate the acid</u>, so we can <u>discard a.</u>

<u />

Finally, for d when we add H^+ the <u>hydronium ion will react with aniline</u> (a base) and will produce an <u>ammonium ion</u>. This ammonium ion have a <u>positive charge</u>, therefore the <u>polarity will increase</u> and the molecule would be more soluble on water (figure 2).

I hope it helps!
