Describe the capillary action in acetone compared to water

Answers

Answer 1

Answer: Capillary action is defined as the ability of a liquid to go up a narrow space without the help or opposition of external forces. One of the most important factors affecting capillary action is the intermolecular forces within a substance. The higher the IMF, the greater the capillary action. The H-bonding in water gives it greater IMF than acetone, so water has greater capillary action.

Answer 2

Answer: Liquid going up a thin space without the assistance off an opposite or opposing force

Why would an electrician use parallel circuits to wire the lights in each room of a house instead of using a series circuit?A. When electricians get their license, they are only licensed to install parallel circuits. Most electricians aren't certified to install series circuits. B. Parallel circuits prevent electrons from flowing if part of the circuit is broken and therefore prevent fires. Series circuits cause more fires because electrons still flow. C. Electrons continue to flow in a parallel circuit even if part of the circuit is broken. In a series circuit, a break such as a burned out lightbulb would cause the current to stop in the whole room. D. Parallel circuits are much easier to wire and are required by the electrical code for housing construction in most communities. Series circuits are sometimes used with special approval.

Why is it important for a scientist studying greenhouse effect to know about mater,forces and energy

Answers

In the 19th century, scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet's temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. At the turn of the century, Svante Arrhenius calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed his idea as faulty. In 1938, G.S. Callendar argued that the level of carbon dioxide was climbing and raising global temperature, but most scientists found his arguments implausible. It was almost by chance that a few researchers in the 1950s discovered that global warming truly was possible. In the early 1960s, C.D. Keeling measured the level of carbon dioxide in the atmosphere: it was rising fast. Researchers began to take an interest, struggling to understand how the level of carbon dioxide had changed in the past, and how the level was influenced by chemical and biological forces. They found that the gas plays a crucial role in climate change, so that the rising level could gravely affect our future. (This essay covers only developments relating directly to carbon dioxide, with a separate essay for Other Greenhouse Gases. Theories are discussed in the essay on Simple Models of Climate.)

Which of the following materials is not considered to be a semiconductor? germanium tin silicon aluminum

Answers

Tin and Aluminum are not considered as semiconductors but rather conductors themselves because they are metals. Semiconductors are in general elements from column IV or or compounds of columns III and V of the periodic table.

Germanium and silicon are semiconductors because they are metalloids.

Aluminium is not considered to be a semiconductor.

For the same mixture, under the same conditions described in problem 7, calculate keq for 2nh3 (g) n2 (g) + 3h2(g). how is the keq for a forward reaction related to the keq for a reverse reaction

Answers

Answer: The relation between the forward and reverse reaction is $K_f=(1)/(K_r)$

Explanation:

For the given chemical equation:

$2NH_3(g)\rightleftharpoons N_2 (g)+3H_2(g)$

The expression of equilibrium constant for above equation follows:

$K_f=([N_2][H_2]^3)/([NH_3]^2)$ .......(1)

The reverse equation follows:

$N_2 (g)+3H_2(g)\rightleftharpoons 2NH_3(g)$

The expression of equilibrium constant for above equation follows:

$K_r=([NH_3]^2)/([N_2][H_2]^3)$ .......(2)

Relation expression 1 and expression 2, we get:

$K_f=(1)/(K_r)$

Hence, the relation between the forward and reverse reaction is $K_f=(1)/(K_r)$

Electrons are capable of emitting energy in the form of light at very narrow ranges of wavelengths. These wavelengths can be measured to find the electron's a. mass.
b. density.
c. energy level.
d. specific heat.

Answers

The correct answer is (C) energy level.

The explanation:

When the electrons release photons , and those photons are at different levels

of energy . So we can define the electron's energy level from this photons which

tell us the energy level they are on.

C. Electrons release photons at different energy levels which would tell us which level they are on.

Which task most likely involves a calculation that uses moles?

What do you mean by mole ?

The term mole is defined as a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.

A mole is the amount of material including 6.023 × 10²³ particles. 1 mol = 6.023 × 10²³particles. This number is also called Avogadro's number.

In determining the number of atoms that makes up a substance, the number of moles is very necessary.

The mole is the favorable unit of quantity of particles. It can be likened to a quantity of things in everyday life like a dozen, a score and a gross.

A mole of any substance contains 6.023 x 10²³ particles

These particles can be atoms, protons, neutrons, electrons etc.

Thus, to find the number of atoms, we must know the number of moles.

Which species represents a chemical compound?
(1) N2 (3) Na
(2) NH4+ (4) NaHCO3

Answers

The species that significantly represents a chemical compound is known as NaHCO3. This is also known as Sodium bicarbonate or sodium hydrogen carbonate. Thus, the correct option for this question is D.

What is a Chemical compound?

A chemical compound may be defined as a type of chemical substance that is mainly composed of many similar molecules that contain atoms of more than one chemical element. These atoms are typically held together by chemical bonds.

According to the context of this question, Na is sodium and N2 is dinitrogen or simply nitrogen gas. Both these chemical constituents are classified as the type of chemical element. While NH4+ is a polyatomic ion which is known as an ammonium ion.

So, NaHCO3 is classified into the category of a chemical compound. This is because it mainly consists of sodium, hydrogen, carbon, and oxygen.

Therefore, the species that significantly represents a chemical compound is known as NaHCO3. This is also known as Sodium bicarbonate or sodium hydrogen carbonate. Thus, the correct option for this question is D.
