The tempo of the excerpt can best be described as Adagio.
<h3>What is an adagio tempo?</h3>
This refers to when the tempo of a musical piece is done slowly or rather in slow time.
This enables for powerful music as it feels like every part of the musical piece by Maria Szymanowska is heard individually.
Rest of the question talks about an excerpt from a music piece by Maria Szymanowska.
The music piece is a Mozart Piano Concerto.

The pH shows the degree of acidity of alkalinity of a solution. The pH of the HF can be obtained from the ICE table.
<h3>What is pH?</h3>
The term pH refers to the hydrogen ion concentration of a solution. Recall that acids produce hydrogen or oxonium ion in solution.
The first step to determine the pH of the HF solution is to set up the ICE table as shown;
HF + H2O ⇄ H3O^+ + F^-
I
C
E
The values of the initial concentration of HF as well as the Ka of HF are not given. If these two values are give, the pH can be obtained from;
Ka = [H3O^+] [ F^-]/[HF] Knowing that [H3O^+] = [ F^-] = x

<h3>Answer:</h3>
AC ∈ {4, 5, 6, 7}
<h3>Explanation:</h3>
When two sides of a triangle are specified, the allowable values for the length of the third side are between the sum and difference of the given sides.
In ∆ACD, sides DA and CD are both given as length 4. Thus the possible range of values for side AC is 0 – 8. The extremes of this range result in ∆ACD having zero area, so we assume they are not of interest.
In ∆ACB, sides AB and BC are given as having lengths 3 and 6. Thus the possible range of values for side AC is 3 – 9. The extremes of this range result in ∆ACB having zero area, so we assume they are not of interest.
The integers that are in both ranges and that give triangles with non-zero area are ...
... AC ∈ {4, 5, 6, 7}
