Consider this reaction:
aalyn [17]

Answer:

\large \boxed{\text{C. 112 L}}

Explanation:

We can use Avogadro's Law: Equal volumes of gases under the same conditions of temperature and pressure contain the same number of molecules.  

To say it another say, gases react in the same volume ratios as their coefficients in the balanced equation.

  H₂  +    Cl₂  ⟶ 2HCl

1 mol + 1 mol ⟶ 2 mol

  1 L  +   1 L    ⟶   2 L

Thus,

\text{Volume of HCl} = \text{56 L Cl}_{2}  \times \dfrac{\text{2 L HCl}}{\text{1 L Cl}_{2}} = \textbf{112 L HCl}\\\\\text{The volume of HCl is $\large \boxed{\textbf{112 L}}$}

The electrophilic bromination or chlorination of benzene requires ______ along with the halogen.
Oksanka [162]

The electrophilic bromination or chlorination of benzene requires Lewis acid along with the halogen.

<h3>What is bromination of benzene?</h3>

The bromination or chlorination of benzene is an example of an electrophilic aromatic substitution reaction.

During the reaction, the bromine forms a sigma bond to the benzene ring, yielding an intermediate. Subsequently a  a proton is removed from the intermediate to form a substituted benzene ring.

This reaction is achieved with the help of Lewis acid as catalysts.

Thus, the electrophilic bromination or chlorination of benzene requires Lewis acid along with the halogen.

At noon on a clear day, sunlight reaches the earth\'s surface at Madison, Wisconsin, with an average power of approximately 8.00
Archy [21]
Energy transferred per second in given area:
8000 x 3.9 / 10000
Energy transferred = 3.12 J

Using Planck's equation:
E = nhc/λ
n = (3.12 x 510 x 10⁻⁹) / (3 x 10⁸ x 6.63 x 10⁻³⁴)
n = 8 x 10¹⁸ photons
