1. Air boiled out of water as steam is rich in ?

Chemistry
1 answer:
Colt1911 [192]3 years ago
4 0

Answer:

<u><em>1. The air boiled out of water as steam is rich in water vapor, </em></u><em><u>H₂O</u></em><u><em>(g)</em></u>

<u><em></em></u>

<u><em>2. Benzene reacts with hydrogen in the presence of nickel catalyst at 180°C to give cyclohexane.</em></u>

Explanation:

<em></em>

1. When water boils liquid water passes to gaseous phase.

Water in gaseous phase is named water vapor or steam.

This happens around 100ºC, depending on the atmospheric pressure.

The air that is around the boiling water will carry that steam, becomind an air rich in water vapor, H₂O(g)

2. Benzene has chemical formula C₆H₆.

It is a cyclic unsaturated hydrocarbon. Benzene contains 3 double bonds.

When unsaturated hydrocarbons are heated in the presence of nickel catalyst, the double bonds are broken, forming single bonds and adding the needed hydrogen to the chain: one to each carbon that had a double bond transformed into single bond.

Thus, the product of the catalytic hydrogenation of benzene, C₆H₆,  is cyclohexane, C₆H₁₂

If a uranium atom undergoes both alpha and gamma decay, what happens to it?
WARRIOR [948]

If a uranium atom undergoes both alpha and gamma decay, then it means that there will be formation of one helium particle which is also known as alpha particle and gamma decay is the radiation or release of energy. Whereas in a radioactive reaction, Uranium-235 absorbs a neutron and splits into two new atoms.

hope this helps

Given pH = 3.50 Find: [H3O+] and [OH-] Is this acidic, basic or neutral?
lys-0071 [83]

Answer:

Explanation:

Given parameters:

           pH = 3.50

Unknown:

    concentration of [H₃0⁺] = ?

    concentration of [OH⁻] = ?

Solution:

In order to find the unknown, we use some simple expressions which best explains the pH scale and the equilibrium systems of aqueous solutions.

         pH = -log₁₀[H₃O⁺]

         [H₃O⁺] = inverse log₁₀ (-pH) = 10^{-pH} = 10^{-3.5}

          [H₃O⁺] = 3.2 x 10⁻⁴moldm⁻³

       

For the  [OH⁻]:

       we use : pOH = -log₁₀ [OH⁻]

     Recall: pOH + pH = 14

                  pOH = 14 - pH = 14 - 3.5 = 10.5

  Now we plug the value of pOH into pOH = -log₁₀ [OH⁻]

                                   [OH⁻] = 10^{-pOH}

                        [OH⁻] = 10^{-10.5} = 3.2 x 10⁻¹¹moldm⁻³

The solution is acidic as the concentration of H₃0⁺ is more than that of the OH⁻ ions.

Which structure is located between the auricle and the eardrum? O stirrup O ear canal O auditory nerve Ocochlea​
Damm [24]

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>
