I believe this pertains to chemical reaction? So my guess would be answer A “Fire burning”

Don’t quote me though lol.

Following are the response to the given question:

Explanation:

The number of shells

n = 4

Calculating the spectral line:

= \frac{n(n-1)}{2}\\\\ = \frac{4(4-1)}{2} \\\\= \frac{4\times 3}{2}\\\\ = \frac{12}{2}\\\\ = 6

Need asap! Step-by-step pls: Determine the empirical formula: 32.37% Na, 22.58% S, 45.05% O​
Ludmilka [50]

1) divide each percentage by the relative atomic mass of the element

2) divide all results by the smallest number

3)multiply by a whole number to get the simplest whole number ratio (if necessary)

that is to say:

Na                                   S                            O

32.37÷23                 22.58÷32                45.05÷16

= 1.407                       = 0.7056               = 2.816       (to 4 significant figures)

the smallest number here is 0.7056 so:

1.407÷0.7056        0.7056÷0.7056       2.816÷0.7056

=1.99 approx.2                   = 1                   3.99 approx. 4

here there is no need to carry out step 3 as ratio obtained is already a simplest whole number  ratio

so empirical formula is: Na₂SO₄

In this drama, a crucible would represent the constant building action leading to the climax of the pot.

What is crucible?

A crucible is a ceramic as well as metal vessel used to melt metals or subject other substances to extremely high temperatures. Crucibles can be made from any material that can withstand temperatures high enough to melt and otherwise change their contents, despite historically being most frequently made of clay. The crucible's shape has changed over time, with designs that take into account both regional variation and the process for that they are used. The earliest crucible forms date to Iran and Eastern Europe in the sixth or fifth millennia B.C.

Similar to the contents of a crucible, the characters seem to be constantly enduring severe trials; in this case, the witching trials. The crucible would, in my opinion, symbolize the town itself and its residents. The symbolism of this suggests a theme of the townspeople going through the witching trials and coming out with a "refined" lesson. The unnecessary accusations and trials will teach a hard lesson to the people who live within the town and influence their future.
