If the energy difference between two electronic states is 214.68 kJ / mol , calculate the frequency of light emitted when an ele
atroni [7]

{\qquad\qquad\huge\underline{{\sf Answer}}}

Here we go ~

Energy difference btween the two electronic states can be expressed as :

{ \qquad \sf  \dashrightarrow \: \Delta E = h\nu}

[ h = planks constant,{\: \nu }= frequency ]

\qquad \sf  \dashrightarrow \:214.68 = 39.79 \times 10 {}^{ - 14}  \times  \nu

\qquad \sf  \dashrightarrow \: \nu =  \cfrac{214.68}{39.79 \times 10 {}^{ - 4} }

\qquad \sf  \dashrightarrow \: \nu =  \cfrac{214.68}{39.79 }  \times 10 {}^{14}

\qquad \sf  \dashrightarrow \: \nu  \approx  5.395 \times10 {}^{14}  \:\:hertz

1) A box has a mass of 8 kg and a volume of 2 m? What is its density? |
pentagon [3]

\huge\boxed{4\ \text{kg/m$^3$}}

We know that \rho=m\div V, where \rho is density, m is mass, and V is volume.

Substitute in the values we know and solve:

\begin{aligned}\rho&=8\div2\\&=\boxed{4}\end{aligned}

Consider the balanced equation below. 8H2 + S8 Right arrow. 8H2S Based on the mole ratios, what can most likely be predicted? 1
Arte-miy333 [17]

Answer:

8 mol of hydrogen will react with 1 mol of sulfur.

Explanation:

We'll begin by writing the balanced equation for the reaction.

This is given below:

8H2 + S8 —> 8H2S

Now, let us carefully observe the mole ratio of the reactants.

This is illustrated:

The mole ratio of the reactants ( i.e H2 and S8) is 8 : 1

From the balanced equation above,

We can thus, concluded that:

8 moles of H2 will reacted with 1 mole of S8.
