Mnenie [13.5K]

Answer:

Weak acid

Explanation:

A titration curve is a graphical description of the change in pH of the solution in the conical flask as the reagent is added from the burette. A titration curve can be plotted for the different kinds of acid and base titrations. The volume of the titrant is always plotted as the independent variable and the pH of the solution as the dependent variable. The equivalence point is read off from the titration curve. A titration curve is very important because it shows the pH at various points during the titration.

A weak acid/strong base titration leads to an equivalence point above 7. From the question, we were told that the pH at equivalence point lies around 8. Hence the unknown substance must be a weak acid.

erastova [34]

Answer:

The volume of the rectangular prism is 77.616 cm³

Explanation:

Here is the remaining part of the question:

Part B:

What value should you use as the area of the base when calculating the answer to Part C.

Part C:

Using the correct answer from Part B, calculate the volume of a rectangular prism with a length of 5.6 cm , a width of 2.1 cm , and a height of 6.6 cm Part B answer: 11.76 cm^2

Explanation:

The volume of a rectangular prism is given by:

V = l×w×h

Where V is the volume of the rectangular prism

l is the length of the rectangular prism

and w is the width of the rectangular prism

Recall that the Area (A) of the base of the rectangular prism can be calculated by using

A = l × w

Hence, the volume of the rectangular prism can also be calculated by substituting this into the equation to give

V = A × h

From the question, the correct answer from part B for the area of the base is 11.76 cm^2; and the height (h) is 6.6 cm

Hence, the volume of the rectangular prism is

V = A × h

V = 11.76 cm² × 6.6 cm

V = 77.616 cm³
