Which structure is located between the auricle and the eardrum? O stirrup O ear canal O auditory nerve Ocochlea​

Chemistry
1 answer:
Damm [24]3 years ago
3 0

Answer:

The structure that is located between the auricle and the eardrum is the ear canal.

Explanation:

The ear canal, or external ear canal, is a a tubular hole about 30 mm long that runs from the auricle to the eardrum, forming part of the external ear.

Its function is to conduct sound, in the form of vibrations, from the outside to the eardrum. It also has the function of producing a viscous secretion called cerumen, capable of trapping dust particles and small foreign bodies.

Other options are not correct because:

  • <em>Stirrup is located in the middle ear, along with the anvil and hammer. </em>
  • <em>Cochlea is in the inner ear and continues with the auditory nerve.</em>

What is not represented by a balanced chemical equation?
astraxan [27]

Answer is: 4) The same subscripts are on each side of the equation.

For example, balanced chemical reaction:

2Mg + O₂ → 2MgO.

1) The same number of atoms is on each side of the equation: two magnesium atoms and two oxgen atoms.

2) The formulas for all substances are correct: in magnesium oxide (MgO), magnesium has oxidation number +2 and oxygen -2, so formula is good, because compound must be neutral.

3) The same mass is represented on each side of the equation: because there is same number of atoms, the mass is the same.

4) The same subscripts are on each side of the equation: oxygen does not have same subscripts.

If solutions of nh4cl(aq) and nh3(aq) are mixed, which ions in the resulting solution are spectator ions in any acid-base chemis
Gwar [14]
If solutions of nh4cl(aq) and nh3(aq) are mixed, the ions in the resulting solution that would be the spectator ions in any acid-base chemistry occurring in the solution would be the chloride ions. The mixture is a common buffer of ammonia and ammonium chloride.  NH4Cl is a salt that is soluble in water dissociating into NH4+ and Cl-. The chloride ions are the spectator ions while NH4+ ions would be the conjugate acid for the buffer solution. Buffer solutions are solution which would resist change in pH when acid or a base is being added to the solution. The equilibrium reaction of the buffer solution in this problem would be

NH3 + H2O = OH– + NH4+

The temperature at the surface of the Sun is approximately 5,150 K, and the temperature at the surface of the Earth is approxima
dezoksy [38]

Answer:

ΔS = 16.569 J/K

Explanation:

In this case, we need to use the correct expression to solve this. In thermodynamics, the expression to use that puts a relation between heat, temperature and entropy is the following:

ΔS = Q/T

To determine the entropy change of the universe, we need to sum the entropy change of Earth and the entropy of the sun.

As the sun is transfering radiation to Earth, the sun is losing energy, therefore, heat is negative, while Earth receives the heat, so it's positive. Calculating the entropy for the sun and Earth:

ΔSs = -Q/Ts

ΔSe = Q/Te

ΔSu = ΔSe + ΔSs

Let's calculate both entropies by separate:

ΔSe = 5x10^3 / 285 = 17.54 J/K

ΔSs = -5x10^3 / 5,150 = -0.971 J/K

Therefore, the entropy of universe:

ΔSu = 17.54 - 0.971

ΔSu = 16.569 J/K
